How to replace an old toilet with a new one. How to replace a toilet bowl: dismantling the old one and installing a new one with your own hands

Reading time ≈ 4 minutes

Sooner or later, the time comes when the old toilet in the apartment becomes unusable, and it has to be replaced with a new one. Most often, replacing a toilet bowl can seem expensive to the average tenant if a plumber is called. However, armed with a certain set of tools and using some skill, you can replace the toilet on your own, and the recommendations below will help you carry out this procedure efficiently and at minimal cost.

Before replacing the toilet, do not forget to drain the water!

First of all, you should decide whether it will be a complete replacement of the unit, or, say, a partial replacement of the toilet cistern. In the first case, it is worth starting with the choice of a model of a new toilet bowl, namely, with the selection of a unit of suitable sizes and configurations. Just like the old toilet bowl, the new device should provide users with maximum comfort conditions, therefore, immediately before replacing and installing the toilet bowl, it is necessary to measure the toilet, and already taking into account these indicators, choose the model that will fit into the room correctly. Namely:

• the distance from the front door to the toilet must be at least 60 cm;
• the distance from the unit to the side walls must be at least 20 cm on both sides.

It should be borne in mind that when replacing a toilet bowl in an apartment, some models will move forward significantly due to the fastening features.

In the event that only the replacement of the toilet cistern is required, it becomes impractical to purchase the entire set (toilet plus cistern). One way or another, any plumbing store can offer flush tanks of any configuration: built into the wall, mounted on the toilet shelf, and also installed under the ceiling. It is worth choosing from the presented assortment based on the characteristics of the room and your own preferences.

Now directly about replacing the old toilet. The whole process begins with the dismantling of the old unit. If we are talking about replacing a relatively new device connected to a sewer system made of plastic pipes, there should not be any special problems here. And if, for example, a toilet bowl in Khrushchev is to be replaced, then everything is much more complicated here.

In this case, a variety of difficulties may arise. So, the dismantling of the tank can be complicated by the poor condition of the fasteners. Over the years of service, the fixing bolts rust, which makes it difficult to remove them. When dismantling the toilet itself, as a rule, similar problems arise with fasteners, as well as difficulties with disconnecting the outlet from the cast-iron sewer. In those years, such connections were made by sealing with tow, followed by sealing with cement mortar. Of course, the undocking of such connections is a very time-consuming process.

If, when replacing an old toilet bowl with a new one, there is no need to maintain the integrity of the old unit, then the old toilet bowl can simply be broken into several parts with a hammer. Dismantling the toilet bowl while maintaining its integrity can only be performed by a qualified specialist. After all the fasteners are disconnected, the most difficult task - disconnecting the outlet from the sewer pipe - is overcome, you can proceed with the installation of a new toilet bowl.

As a rule, the entire installation sequence of a new unit is described in the attached instructions, and the video on replacing the toilet presented on the site further clarifies the installation picture, so we will focus only on the key points.

So, do-it-yourself toilet replacement at the stage of installing a new device includes the following steps.

Thus, this short guide with a photo on how to replace a toilet will help you not only do the whole range of activities on your own, but also save on plumbing services, as well as gain invaluable experience in replacing plumbing.

Having understood the toilet installation technology, you can save on plumbing services and do the job as efficiently as possible. The toilet bowl can be mounted in the traditional way or in a more modern way - with installation. In the second case, the drain tank will be hidden in the wall, which will favorably affect the interior of the room.

You are provided with instructions on how to complete each of the listed installation options.

In the case of installing a toilet bowl on the installation, the listed list will expand with the corresponding set. Everything you need is bought at any plumbing store.

Dismantling the old toilet

First step . Shut off the water supply and drain all the liquid.

Second step. We unscrew the hose through which the tank is connected to the water supply.

Third step. We unscrew the fasteners of the tank. If they are rusty, we arm ourselves with a screwdriver or open-end wrench. We press the bolt head with the selected tool and unscrew the nut with an adjustable wrench. If it doesn’t work, pre-soak the nut with kerosene. We remove the tank.

Fourth step. Dismantling the toilet bowl.

Fifth step. Disconnect the toilet drain from the sewer.

In old buildings, plums are usually fixed with cement plaster. To destroy it, use a hammer and a chisel. We need to prick the cement and gently shake the toilet to the sides. The drain should turn and loosen. We tilt the product, allowing the remaining water to drain into the sewer.

If the toilet had an outlet to the floor, you need to clean off the wax ring

Sixth step. We close the sewer hole with a wooden or other suitable plug.

Important! Sewer gases do not have the most pleasant smell. However, they are poisonous and highly flammable. Be sure to keep this in mind as you work.

Getting ready to install

The base for the installation of the toilet must be level. There are several options for the development of events, namely:

• if the floor is tiled and does not have level differences, we do not carry out any preliminary measures to level the base;
• if the floor is tiled and not even, install the toilet with chopsticks. To do this, holes are drilled in the floor, chopsticks are hammered into them according to the level, and after that the toilet bowl is attached to the chopsticks with screws;
• if a tile replacement is planned, we dismantle the old cladding and fill in a new screed, if the old one has level differences;
• if the toilet is installed in a new house or apartment without any finishing, we fill in the screed and lay the tiles.

We pay attention to pipes. Sewer from debris and various deposits, we install a tap on the water supply (if it was absent before) to shut off the water supply to the tank.

How to install a conventional toilet

As a rule, when selling, the toilet bowl and the tank are disconnected. The internal fittings of the barrel are most often already assembled, which greatly simplifies the installation process.

First step. We put the toilet bowl in its place and make marks at the attachment points.

Marks on the floor for fasteners

Second step. We remove the toilet bowl and drill mounting holes in the marked places.

Third step. We drive the dowels into the mounting holes.

Fourth step. Installing the bowl. We insert fasteners through special sealing gaskets. Tighten fasteners. You should not pull too hard - you can damage either the fasteners or even the toilet itself. We pull until the sanitary ware is firmly attached to the surface. From above we close the fasteners with plugs.

Fifth step. We mount the cover and seat. The manual for their assembly usually comes with the toilet, so we will not dwell on this event separately.

Sixth step. We connect the toilet to the sewer. The procedure depends on how the toilet outlet is connected.

If the release is done into the wall, we work like this:

If the release to the floor is being arranged, we do the following:

Helpful advice! If the toilet bowl is connected to the drain pipe using a corrugation, sealing can be abandoned in most cases, because. the design of such an adapter hose is itself able to provide a sufficiently tight fit.

Seventh step. We carry out the installation of the tank. Drain mechanisms, as a rule, are sold already assembled. If the mechanism is disassembled, assemble it according to the manufacturer's instructions (the assembly order for different models may vary slightly).

We take the gasket from the kit and install it in the water hole in our toilet. Install the tank on the gasket and tighten the bolts.

Fasteners are most conveniently installed like this:

Eighth step. We connect the tank to the water supply using a flexible hose. We turn on the water supply and check the quality of the system. If it digs somewhere, tighten the nuts a little. The level of filling the tank with water is adjustable by moving the float lower or higher.

We let the tank fill several times and drain the water. If everything is fine, we take the toilet into permanent operation.

Modern installation. A special wall installation is used, in which the mechanism of the tank is hidden. As a result, only the toilet bowl and the drain button remain visible.

The first stage is the installation of the frame

We carry out the installation of a metal frame with fasteners. We attach the tank to the frame. The position of the frame is adjustable with brackets at the top and screws at the bottom. Frames are sold separately, have the same structure and are suitable for use in combination with any toilet.

The assembled structure will have a height of about 1.3-1.4 m. The width should exceed the width of the tank.

The second stage - we hang the tank

We perform the installation in compliance with the following recommendations:

• we place the drain button at about a meter distance from the floor;
• between the attachment points we maintain a step equal to the distance between the eyes of our toilet bowl;
• the drain pipe should be located at a height of about 220-230 mm;
• we hang the wall-mounted toilet at a distance of 400-430 mm from the floor. These are average values. In general, focus on the growth of future users;
• between the drain tank and the wall we maintain no more than 15 mm distance.

The third stage - we mount the finished installation

We first check the evenness of the wall with a plumb line. When deviations are found, do the following:

The fourth stage - install the tank

First we connect the tank. The drain may have top and side outlets. Almost all modern models of tanks allow you to choose between these two options.

Important! When installing the toilet on the installation, it is better to refrain from connecting the tank with a flexible hose. will last much longer than a hose. Would you like to destroy the frame skin in the near future for the sake of a five-minute replacement of such a hose? That's it!

For connection, it is best to use plastic pipes. All necessary fasteners usually come with the tank. Separately, you have to buy only a panel for the drain buttons, and even then not always.

We connect the release of our toilet bowl with the sewer. The most convenient way to do this is with a corrugation. We check the tightness of the structure. If everything is fine, turn off the water, temporarily turn off the toilet from the drain and remove the bowl to the side.

Important! The procedure for connecting the cistern to the toilet and plumbing may vary depending on the model of the product. We clarify these points in a separate order and follow the manufacturer's instructions.

Fifth stage - we sheathe the installation

To do this, we use moisture-resistant drywall with a thickness of 10 mm. It is recommended to fix it with a double layer. First we do the following:

• we screw the pins for hanging the toilet into the frame (they are included in the kit);
• close the drain holes with plugs (also from the kit) so that they are not clogged with dust and debris;
• we make holes in drywall for pins, pipes and a drain button.

We fasten the sheathing sheets to the frame with the help of special self-tapping screws. Keep the fastening step at the level of 30-40 cm. The design will be small in size and weight, so there are no strict recommendations regarding the distance between the fasteners.

We tile drywall with tiles or finish it in another way at our discretion.

Helpful advice! Before starting to tile the box with tiles, we install a plug and a cuff in the place of the future location of the drain button. They are usually included in the kit.

Stage six - install the toilet

To do this, we connect the outlet of the bowl to the sewer hole and hang the product on the pins (we installed them in the previous stages of work). You can follow these steps in reverse order, whichever is more convenient for you. Tighten the fixing nuts.

Important! Previously, the tile that will be in contact with must be covered with a layer of silicone sealant (a gasket can be installed instead).

You can turn on the water supply and use the toilet for its intended purpose.

The assembly instructions for the installation remain the same. Only the order of installation of the toilet bowl changes. Work in the following order.

First step. Lock your knee firmly. Metal fasteners will help you with this.

Second step. Treat the toilet outlet with technical ointment.

Third step. Install the toilet in the place intended for it. Circle the outline of the sanitary ware and mark the holes for the fasteners.

Fourth step. Remove the toilet and install the mounting brackets from the kit according to the marking.

Fifth step. Install the bowl, press its outlet into the vent pipe and secure the sanitary ware with the bolts or other fasteners included in the kit.

Sixth step. Connect the tank to the drain. Installation and connection of this element is carried out in the same way as in the case of mounting a wall-mounted toilet model.

Seventh step. We bring the drain button into a pre-prepared hole in the casing, turn on the water supply and check the operation of the toilet bowl. If everything is fine, we accept the product for permanent operation.

Installing a toilet bowl with your own hands is a rather complicated task, and will require certain skills and tools. However, if you do it yourself, then, firstly, you can save on a specialist, and secondly, gain invaluable experience - after all, new skills are always useful.

Toilets, due to their diversity, differ in the method of installation. The most common type is outdoor.

Required Items

Before you install the toilet with your own hands, you need to make sure that you have the items that will be needed in this matter:

• Perforator;
• Adjustable and wrench;
• A hammer;
• screwdrivers;
• sealant;
• Transfer cuff for connection to a cast-iron socket;
• A container where water will drain from the dismantled plumbing fixture, as well as rags to wipe.

Training

Before you change the toilet with your own hands, you will need to carry out preparatory measures. First you need to determine how the new device will be connected to the sewer. There are three cuff options:

• Corrugated - this connection method is the most cost-effective. However, with this method, installation cannot be carried out close to the sewer pipe.

Before you connect the toilet with a corrugated cuff, you should make sure that the room has the necessary space and will comfortably fit the equipment.

• Direct - a universal way to connect, allows you to do it reliably. If you have any hesitation in choosing a method of connecting to the sewer, then this option is the best.
• Eccentric - a method of connecting to the sewer, it is convenient if the centers of the drain and socket are displaced.

Connecting the toilet drain with a cuff

To properly install the toilet with your own hands, it is recommended to dismantle the old liner and install a new one. Its length should be equal to the distance from the connection of the water supply pipe to the toilet connection, plus 15-20 cm.

Dismantling

Before you change the toilet, you will need to dismantle the old one. For this you will need:

• Turn off the water supply;
• Disable eyeliner;
• Drain the contents from the barrel;
• Remove barrel. If the old toilet is not planned to be used anywhere, then this can be done with a hammer, otherwise you will have to act carefully;
• Remove the fastening tools with which the bowl was mounted, remove it by pouring out the remaining water.

If it is decided to use brute force to dismantle the old toilet bowl and use a hammer or punch, then you should be careful not to allow various fragments to enter the sewer, which will cause a blockage.

If there is any support made of wood or other material under the old bowl, then it must be removed. The void that remains after this operation must be filled with cement and leveled with a spatula.

Toilet installation

• Before you put the toilet on your own, it is necessary to clean the socket from rust and dirt. Then it is necessary to cover with sanitary sealant and connect the cuff.

When the toilet is removed, odors come out of the sewer. So that they do not distract from work, the sewer hole must be closed with something, for example, plugged with rags.

• Do-it-yourself toilet installation continues with markings for dowels. To do this, the bowl is placed in the place where it should be installed, and the holes are marked. Drill holes according to this marking and insert dowels into the holes.

In some models, the holes are drilled at an angle. In this case, to install the toilet in the holes, it is necessary to drill at the same angle.

• When the dowels are inserted, the bowl is put in place and connected to the cuff from the sewer socket. Then the screws are tightened, on which plastic washers are put on.

It is not right to immediately tighten the screws too much. First you need to lightly bait, and evaluate whether the installation is smooth. If not, then level it by substituting plastic linings under it. Only then can you tighten it.

The bowl is installed according to the markup

• To install the toilet bowl, you yourself need to assemble the barrel if it is delivered disassembled. Here everything is done according to the instructions that are attached by the manufacturer.

All moving parts must not come into contact with each other or the walls of the drain tank.

• The next step is to install the drain tank on the bowl. Fasteners are usually made using bolts, which should be tightened evenly. When the installation is done, a cover is put on the tank and a drain button or lever is installed.

• The final moment of self-installation of the toilet bowl is the connection of the liner.

When the eyeliner is connected, do not rush to turn on the water. First you need to check for damage to all components of the structure visually. And only when you are sure that everything looks normal, you can open the water, fill the reservoir and try to flush. If there are leaks, they need to be fixed.

The need to install new appliances arises during major repairs or due to the failure of plumbing. Do-it-yourself toilet replacement saves a lot of money, and knowing the process will help you choose the best way to install it. In this case, the help of professionals is not required.

High-quality preparation for the replacement of the old toilet with a new one is the key to a successful result. First of all, you need to get a set of tools, building materials and detailed instructions for those who do such work for the first time.

Need to replace toilet

It is not always necessary to change the plumbing fixture if there are malfunctions in the sewer system. If water constantly leaks from the tank in the bathroom, this is a serious reason to think.

When it drips onto the floor, and all the pipe joints are in order, then, usually, the cause of the problem is the presence of a chip or crack. It is possible to eliminate the leak in this situation only temporarily - the toilet should be replaced as quickly as possible.

If the water from the drain tank drains into the sewer along the wall of the bowl, then most likely the installation of new plumbing will not be required, since the leaky valve most likely became the cause of such a malfunction. Since all internal elements for flush tanks are sold separately, they only need to be exchanged for new products.

Plumbing faience and porcelain are rather fragile materials that are characterized by instability to sudden temperature changes. The enamel can be covered with a grid of cracks that spoil the external aesthetic component of the device and threaten the complete destruction of the bowl. If chips or other problems have formed on this product, the toilet should be replaced as soon as possible.

None of the users of the toilet can know for sure when the ceramic coating on it will not withstand and burst under the influence of water flows, the weight of a person or as a result of internal stress. It’s good if at this moment the residents are nearby and one of them can quickly eliminate the emergency, otherwise the toilet will need to be repaired by the neighbors living on the floor below.

Another sign of a plumbing problem is the presence of an unpleasant odor. Most often, the cause of it is an improper installation of the sewer system, as a result of which the drains in the pipes stagnate. When everything turned out to be in order with the pipeline, and the faience was clean, the cause of the smell should be sought in the fact that the glossy coating began to collapse.

If the integrity of the enamel has suffered, and the porous structure of the sanitary ware has begun to come into contact with impurities, it begins to absorb unpleasant "aromas". It will not be possible to cope with these odors, since the destruction process is irreversible. In this case, it is impossible to do without how to replace the old toilet with a new one.

Another important reason for dismantling the old and installing new plumbing is the planned renovation in the bathroom. Few property owners decide to keep the old appliance in the event of a redesign in the bathroom.

Since new, more modern products appear on sale regularly, updating a bathroom with the replacement of plumbing can transform its interior beyond recognition. Regardless of whether the classic version or an unusual model from the catalog is chosen, the process of how to properly change the toilet occurs in the same sequence.

The nuances of choosing a new plumbing fixture

Before carrying out repairs in the bathroom, you should carefully prepare for it. It is especially necessary to think about how to change the toilet bowl in the apartment with your own hands when the residents continue to use the toilet.

In this case, plumbing should be changed as quickly as possible, but without the proper organization of repair work, this becomes impossible. First of all, they make a choice of a suitable model, prepare all the tools and building materials, and then proceed to implement their plan.

The most important thing, before you install and dismantle the toilet, is to purchase a new plumbing fixture. Depending on the model chosen, a set of tools and materials is prepared for replacement.

Toilets are of two types:

• floor;
• suspended.

Floor models are more popular and their choice is huge. They are of the "compact", "monoblock" type, with a separate tank and bowl, as well as with a flush system of a hidden design.

A monoblock is a product that combines a water tank and a bowl into a single system. In a toilet bowl - a compact, these two parts are sold as a set and connected during installation - this is the most popular option presented on the domestic market for sanitary products.

A retro model, during the installation of which the tank must be placed under the ceiling and connected to the bowl with a pipeline, has become less and less common in recent years. In them, in order to flush, you should pull the rope or chain with a handle. Such plumbing looks appropriate in a bathroom decorated in the appropriate style.

The modern solution is the arrangement of a hidden drain system. Before replacing an old toilet bowl with a new one of this type, it is necessary to consider the construction of a false wall, behind which a drain tank with an installation system will be hidden. Externally, hidden models look very neat, since only the drain button will be located on the wall, and engineering communications will remain hidden.

The bowl of the hanging toilet bowl is not placed on the floor. It is hung on anchor bolts built into the wall. As a result, there is free space under the bowl and it can be used to good use. This design is also advantageous from a hygienic point of view. It is not difficult to wash the floor under it, but a dirty coating often collects around the floor product.

Another important point that should be considered before replacing the toilet with your own hands is the direction of release from the bowl, which can be of three types:

• at an angle;
• direct;
• vertical.

The most popular option is to use a direct horizontal outlet. In the process of its implementation, the toilet bowl is connected to the sewage drain pipe at the same level. The oblique outlet was used mainly during the years of Soviet high-rise construction, but it can still be found now.

As for devices with a vertical drain, they are usually used in the homes of America and China. Its convenience lies in the fact that the toilet can be located anywhere in the bathroom, and communications are laid in the interfloor overlap. We also implement this arrangement option in domestic sewer systems, but only in private households.

Assembly tool kit

Before carrying out this type of plumbing work, everything that is needed to replace the toilet is prepared in advance from a standard set of tools. Its equipment may vary depending on the state of the outdated toilet equipment that needs to be dismantled, as well as on the type of sewer pipes and the method of attaching the new device.

You will definitely need the following tools:

• hacksaw or grinder;
• perforator;
• screwdriver;
• wrench;
• gun for applying sealant;
• chisel and hammer;
• building level;
• rubber spatula.

You will also need personal protective equipment - special gloves and goggles. A puncher is used to create holes in concrete for dowels, on which a new plumbing fixture is to be mounted. An adjustable wrench is required for work related to connecting plumbing communications.

When tightening the screws, they use a flat or Phillips screwdriver, and for reliable sealing of the joints, use a gun into which a bottle of sealant is inserted. A hammer and a chisel are used when a toilet is being replaced in a Khrushchev with a cast-iron pipe connected to an old sewer riser installed in the Soviet years. To check the correct installation of the bowl, a building level is used.

Related materials

In addition to a set of tools, before you change the toilet with your own hands, you need to purchase building materials for installation, including:

• pipe for connection to the water supply system;
• sealant;
• corrugated pipe for connection to the sewer riser;
• tap;
• FUM tape;
• fasteners.

When a toilet bowl is exchanged - an old product for a new one, the main point is to ensure reliable sealing. Any loose connection or gap may result in a leak. When connecting a plumbing fixture to the sewer system, the best solution is to use silicone sealant in a cylinder.

Before you replace the toilet in an apartment or house, to connect it to a pipeline that drains drains, you should purchase plastic corrugated pipe products. Such a product is convenient in that it is flexible and suitable in most cases. Bending, the corrugation can take a different position, shrinking and stretching. It is suitable for both horizontal outlet and angled outlet.

In order to seal the joints, a sealing tape is used or they act in the old fashioned way, using tow. The set of fasteners includes screws, bolts, dowels, nuts, washers, plugs for connecting all components and carrying out installation work. In the absence of any fastener, it can be purchased additionally.

Demolition of an old toilet

To change the toilet with your own hands, you first perform its dismantling. If the device is not too old, there are usually no problems with this process. When the plumbing model and cast-iron sewer pipes are still Soviet-style, in this case you will have to work hard.

If the device is not in a very bad condition, the dismantling process will not be too laborious:

1. First, before draining the toilet when replacing, block the water pipe.
2. Prepare containers for collecting water and rags.
3. Disconnect the tank by unscrewing the bolts from below.
4. Remove the plastic eccentric or corrugation connecting the outlet of the bowl and the sewer system.
5. Using a regular sponge, remove the remaining water in the container.
6. Using a wrench, unscrew the fasteners located on the sides of the base, there are usually 2 or 4 of them.
7. Use a knife to remove the silicone sealant from under the base.
8. The bowl is removed from the tile.

In the past century, they tried to do all the installation work so that the plumbing would last for more than a decade. Until now, when replacing a toilet bowl in Khrushchev, you can find a device planted on a cement mortar and embedded in a screed with rewinding with rags at the base and, finally, covered with paint in several layers. At the same time, its connection with the sewer pipe turns out to be smeared with a thick layer of solution.

Now this installation method looks ridiculous, but as long as the home craftsman does not have to dismantle the rare device. In the case when ceramics are not a pity, the toilet bowl can be dismantled in parts. To do this, you need a hammer with a chisel.

You must first knock at the junction of the bowl and pipe, at the same time swinging the mount. If the design does not lend itself, you should hit the neck of the plumbing fixture and it will crack. After that, it will be possible to extract it. The main thing at the same time is not to hit the cast-iron pipe with a hammer, since it is fragile and will easily crack.

Features of installing a new product

After you managed to remove the toilet with your own hands, proceed to the installation of a new product. Depending on the model you purchased, the installation process will also differ. Installation of a plumbing bowl with a floor mounting option and an attachment with a hidden tank is carried out in different ways. Detailed instructions can help the home master to cope with the work of installing the toilet bowl.

The process of installing a compact toilet bowl - how to replace it yourself

In order to replace an old appliance with a floor product of the "compact" type when installed on a tiled floor, you need to use the step-by-step description of how to replace the toilet yourself:

1. First of all, determine the location of the new device. The bowl is placed in the bathroom without fastening. You have to try to get on it. It is advisable to try several options.
2. When the exact location is known, the base of the bowl is traced with a washable marker. With it, they also mark the places for attaching plumbing.
3. The product is removed to the side, and after that all the necessary marks remain on the floor. Then, with a drill with a 12 drill, holes are drilled in the tile. If the surface is concrete, then it is better to beat it with a drill at number 12. Dowels are inserted into the prepared holes.
4. Then they take a corrugation or cuff to connect the outlet of the device to the sewer system. The connecting element is placed in place, having previously treated the joint with a sealant.
5. A new corrugated bowl is installed correctly. Bolts are threaded into the mounting ears and screwed in using an adjustable wrench. The main thing when doing this work is not to overdo it and not damage the ceramics.
6. The device is connected to the sewer pipe, treating all joints with silicone.
7. A tank is placed on the bowl.
8. The elements are connected with bolts and the container is connected to the water pipe.

Finally, check all joints, as well as threaded connections for leaks. If no flaws and imperfections are found, you can use new plumbing equipment.

The process of how to change the toilet bowl of such a model on your own is simple, since modern products are designed so that when they are replaced, the floor covering remains intact.

Installation of a hinged bowl and a hidden tank

It should be noted that the work on how to change the toilet bowl of a conventional design for a hanging product with a hidden drain tank differs from the previous version in greater complexity. In this case, not only the replacement of plumbing equipment will be required, but also the repair of the floor covering, the construction of a false wall with further finishing with tiles or other modern materials.

It is necessary to attach the hinged bowl to a solid installation. After finishing the walls, the fixed metal frame will not be visible. When carrying out repairs in a combined bathroom, when decorating the interior, it is advisable to mount a wall-mounted washbasin and a bidet of a similar design.

A detailed description of how to change a conventional toilet bowl to a hinged structure is as follows:

1. Determine the location of the plumbing fixture. A sewer pipe having a diameter of 110 millimeters and a supply is brought to it.
2. They try on the purchased installation, which is a rigid frame for mounting. You need to decide on the height. Standard placement is 450mm from the floor to the seat and 100mm from the floor to the bottom edge of the seat.
3. Using a marker, mark the places of fixation to the floor and wall of the bathroom so that they exactly match the mounting holes.
4. They are prepared using a perforator and a frame is installed. Using the level, check the correctness of the installation work.
5. Water is connected to the drain tank.
6. Included with the installation is a plan for sawing drywall sheets in order to complete the cladding of the installation site. GCR is attached to the metal profile and to the installation. It is better if they are moisture resistant.
7. Finishing is carried out taking into account the personal preferences of the residents.
8. When replacing the toilet bowl, it is connected to a corrugated sewer pipe and a waste disposal system, not forgetting the need for sealing.
9. The bowl is screwed directly to the installation frame through drywall and tiles using studs.
10. The device is connected to the sewer system and the drain tank.

Despite the fact that the process of replacing an old toilet with a hinged product takes a lot of time, the result of such a repair looks stylish and expensive. The work of installing an electronic plumbing fixture with the addition of automatic hygiene functions has much in common with mounting and connecting a conventional product, but there are still nuances.

The fact is that in order to connect an intelligent wall-mounted toilet, it is necessary to provide its power supply. For this, a separate line is usually laid, since smart technology is sensitive to voltage drops in the network.

Most Common Mistakes

Before changing the toilet in an apartment or house, you need to carefully study the instructions of the manufacturers of these products. It is almost impossible to avoid mistakes during the dismantling and installation of plumbing in the absence of relevant experience.

There are several types of plumbing work in which novice craftsmen perform the wrong actions. Their knowledge will help to avoid unpleasant surprises in the implementation of installation activities.

To prevent liquid from stagnating in the sewer pipes, the slope must be observed when installing the sewage disposal system. According to building codes and regulations, it should be from 3 to 5 percent in the direction of the sewer riser. If the question is being considered not only how to change the toilet, but also to move it to another place, this should not be forgotten.

When moving the bowl of the device 1 meter from the riser, it must be raised by 3 - 5 centimeters. And this rule applies to every meter by which plumbing equipment will be displaced. Subject to the implementation of building codes, there will be no problems with the functioning of the sewer riser.

Some property owners are in a hurry to replace the toilet at the very beginning of the renovation in the bathroom. Experts advise avoiding such actions if possible. The fact is that faience plumbing is fragile and with further construction work in the room there is a high probability that it will be damaged. Therefore, it is advisable to change the toilet with your own hands last.

If a bidet is already installed in the bathroom, the hanging bowl should be placed flush with its upper edge. Only in this case, plumbing looks harmonious in the interior of the room and it is convenient to use it.

When replacing sewer pipes, revisions must be installed. Access to hatches should always be free - you can use aesthetic doors to cover them. This requirement should not be neglected, since in the event of an emergency, revisions will have to be used.

Replacing an old toilet with a new one without the help of a professional is quite risky, especially in the absence of experience. When installing plumbing yourself, the main thing is not to rush and follow the instructions.

Any plumbing equipment has its own life, and at some point it may fail. This also applies to toilets. One way or another, during the repair in the bathroom, you will have to think about replacing such a device. As a rule, the call of the master associated with the dismantling and installation of plumbing can be an expensive pleasure. But this work can be done independently.

Nuances of preparation

Before you change the toilet with your own hands, you should plan its future location in the bathroom. In addition, you need to decide on the model of the plumbing device. Old equipment often has an unattractive appearance, and does not correspond to the overall interior design in the event that repairs have been carried out and tiles have been updated. This product can look rather unpresentable, even if it performs its function properly.

The main difference between such models is related to their connection to the sewerage system. This is a different shape and direction of the toilet outlet neck. There are the following varieties:

• devices with oblique release;
• appliances with direct release 90 degrees;
• products with vertical release going to the floor.

Each of these types of sanitary containers has its advantages and disadvantages, but modern latrines, as a rule, are equipped with the units of the first two types.

Before starting work, you need to figure out what exactly needs to be done. Sometimes you need to replace the device completely. If only part of it has become unusable, for example, the toilet bowl has cracked, you can limit yourself to partial restoration.

First of all, you should decide on the choice of the model of the new equipment. For the most comfortable operation, the plumbing fixture must meet certain criteria. Before purchasing a new product, it is recommended to take measurements in the bathroom where the installation of the unit is planned. Given the dimensions obtained, you can choose a modification of plumbing that is ideal for your room.

When installing equipment, you need to consider some parameters. For example, a toilet bowl must be mounted no closer than 60 cm to the front door. There must be a gap of at least 20 cm between the product and the side walls. This will help to easily install, for example, a toilet seat for the disabled.

It should be remembered that in the case when a complete dismantling of plumbing equipment, The location of the new device may change due to the misalignment of the new and old mounting holes and will need to be positioned by slightly moving the device forward or to the side.

If the bowl of the product does not need to be replaced, it would be advisable to think about buying individual parts and mechanisms, rather than a complete set of equipment. In any case, in stores and markets, you can pick up sanitary tanks of any configuration.

This can be a plastic toilet bowl built into the wall or a compact sanitary ware container that is mounted on the shelf of the appliance bowl. However, in some cases, you will have to look for a different tank model. The interior design in the loft style provides for a wall-hung toilet bowl, installed at a low height or under the ceiling. The external decor of the device will depend only on your taste preferences and design ideas.

Materials and tools

Do-it-yourself replacement of a toilet bowl in an apartment is quite a feasible event for a home master. To carry it out, spending a minimum of effort and material resources, while doing the work efficiently, you can, guided by a simple instruction.You only need to have some simple skills.

Of course, in order to cope with such a task, you will need to acquire some tools necessary for the dismantling and subsequent installation of plumbing. For work on changing plumbing, the following are useful:

• hammer drill or impact drill with reliable concrete drill bits;
• a set of wrenches for connecting water hoses and assembling locking valves;
• adjustable wrenches - pipe and "Swedish";
• a hammer;
• screwdrivers - straight and cross;
• bottle of silicone sealant;
• adhesive cement.

When a suitable sample of plumbing equipment is purchased, the issue of choosing water pipes for connecting water to the drain tank should be resolved. In the past, only metal communications were used for this purpose. Today, products made of polypropylene or metal-plastic are increasingly used. They are not as durable as steel counterparts, but the installation process is simplified several times. This distinguishes them favorably from old-style systems - neither special knowledge nor a specific tool is required to assemble a plumbing structure from innovative materials.

Previously, the repair of communications required the use of welding, cutting metal manually with a hacksaw, and threading. In this regard, the work was difficult, long and tiring. Metal-plastic pipes are a completely different matter - they are assembled using standard fittings, and even a person with minimal manual labor can cope with this task.

How to remove an old toilet

To perform such work as replacing a toilet bowl with your own hands, it would be useful to draw up a clear algorithm of actions. This will help reduce the time of the process by eliminating unnecessary intermediate operations and avoid possible missteps.Now we will talk about the actual change of old plumbing equipment. Of particular difficulty is the dismantling of the old model.

In the process of removing such a device, certain difficulties may be revealed. For example, the dismantling of a drain tank may be hindered by fasteners that have come into a substandard state. From constant contact with water for a long period, the mounting screws are covered with a layer of corrosion, which can greatly complicate their unscrewing.

When removing the toilet bowl, there are also usually difficulties of this kind with the removal of fasteners. In addition, it can be problematic to disconnect the outlet from the cast iron pipe sewer. Such connections used to be assembled for winding and smeared with cement mortar. It is clear that it is almost impossible to disassemble such a unit without damaging the parts.

If it is not necessary to maintain the integrity of the old device during dismantling, then the bowl of the device can simply be broken into several pieces. If there is a need to save an old product, it would be appropriate to resort to the help of a qualified specialist.

The most difficult thing in this work is to disconnect the outlet and the sewer pipe. As a rule, over the years of use, a cast-iron pipe is heavily overgrown with rust from the inside, which seals the connection with the toilet to such an extent that it is not possible to simply separate them. In order to solve this issue, we suggest using a grinder. With its help, you simply cut off the cast-iron flange from the outlet of the plumbing fixture.

Methods for installing new plumbing

When planning such work as the dismantling and installation of a toilet bowl, it would be useful to study the device and the principles of installation of plumbing equipment of the main varieties.

Usually, the procedure for installing these devices is described in the instruction manual that comes with the product. Let us consider in more detail only the main points in which you may encounter some difficulties.

First you need to clean the outlet of the sewer pipe and connect it to a corrugated hose. Next, install a new product and outline its contour on the floor. You should also mark the points of fixation of the equipment to the horizontal plane. After, the corrugation is connected to the release of a new model.

As for the installation of the tank, you should start by assembling its internal fittings, and then connect the container to the bowl. At the same time, do not forget to lay the special rubber seals that come with the purchase. After the complete assembly of the device, it is imperative to conduct a test run of the water supply and check the quality of the drain tank. Today, experts distinguish three main ways to install a toilet bowl. Each of them deserves special attention.

Fixation with dowels

The most popular and reliable way to fix the toilet bowl. Holes for fasteners are made in the floor at pre-marked points. After installing the equipment and fix it with dowels. The seam between the floor and the product is sealed with silicone.

This work will not take much time and is not particularly difficult even for a beginner. In addition, the method allows you to firmly install the system, which guarantees its long and successful operation.

Mounting on a hard base

This method has been known for quite a long time. Its essence is that the toilet bowl, the photo of which is presented in the website gallery, is installed on a wood base, fixed in a special niche. Taffeta is laid flush with the floor or so that it rises slightly above it, and poured with a concrete solution. The new model is fixed to the board with screws laid with rubber washers. Of course, before fixing the product, you need to connect it to sewer communications.

This mounting option is rarely used today. This is a very laborious and long process, which does not guarantee special reliability.

gluing

Another almost forgotten method. It consists in applying an epoxy adhesive to the floor and the lower plane of the toilet bowl. To do this, acquire the desired substance and prepare both surfaces. They need to be treated with an abrasive and thoroughly degreased. Next, a thin layer of glue is applied to both planes and the device is installed, pressing it to the floor. It must be said that the complete curing of the composition occurs after 12 hours of exposure. Of course, this method is inefficient and is associated with some difficulties.

I must say that the replacement of plumbing is not as difficult an event as we used to think about it. Such work is within the power of every owner. The main thing is to strictly follow the instructions during the installation of a new product and listen to the advice of experienced professionals.
