How to change a hose on a faucet. Flexible faucet connection

Today, most people choose the flexible faucet connection option. In our material, we will try to study in detail this element of plumbing, as well as understand the reasons for its popularity.

pros

To positive aspects, which has a flexible eyeliner, include:

• Safety during operation;
• Reliable product service with its high quality;
• Flexible system it is convenient to use, it is much more practical than a rigid counterpart;
• Serves long enough;
• Easily mounted and dismantled from the mixer. In fact, it only requires a couple of tools;
• Actually, the product is flexible, and therefore allows you to carry out various manipulations with it - move it on different sides of the mixer without fear of damage;
• Flexible hoses are easy to hide when installing built-in faucets. By placing them in a special box inside the wall. This allows you to make the interior more organic, hide unnecessary elements.

Minuses

But still call flexible eyeliner ideal solution not possible, because it has certain disadvantages.

• Bending, tension and twisting are not allowed, which lead to product failure, possible leaks and flooding;
• It is impossible to use them if there is an open source of flame nearby;
• The flexible hose is unsuitable for very hot water;
• The metal braid oxidizes over time, the corrosion process may begin;
• If it is a bellows line, the water will buzz in it while using water in different rooms.

Kinds

Now there are two types of flexible piping, which is used when connected to faucets:

• Flexible rubber hoses encased in steel braid;
• Bellows eyeliners with better connections.

Braided flexible hoses

Rubber options are produced quite easily, which has a positive effect on the final cost of products. Therefore, they are widely distributed among our consumers. It is also worth noting that some manufacturers produce anti-vibration eyeliners. Their peculiarity lies in the larger diameter of the hose. This avoids unnecessary noise and vibrations, that result from the work pumping systems inside household appliances or plumbing lines. Bellows eyeliners with better connections.

• Read the label carefully, check the specifications of the device, check with the manufacturer. All of them must meet your requirements and the plumbing used.
• Check if the eyeliner seems very light. If this is true, then most likely the material for the braid was aluminum, and the fittings were made of low-grade metal. Over time, such elements simply collapse.
• Never buy a product if its fitting is made of plastic. This is the worst option on the market.
• Check the eyeliner for "oakiness". That's why it is flexible to be elastic. The lack of elasticity indicates poor quality hose. Over time, cracks will appear inside it, or it will burst completely.
• Make sure the fittings are properly crimped, the tubes are fully inserted, and the compression sleeves are made of stainless steel.
• Take a look at the cap nuts. Sometimes they are very light or too thin. Lightness suggests that the fitting may be plastic, or the nut is simply made of low-grade metal. This leads to leaks. The best option is nickel-plated brass. You can check whether it is used or fake by a simple scratch.
• Smell the eyeliner. For all the comical advice, he will give a lot to understand about the product. The presence of a pungent odor indicates the use of technical rubber that is dangerous to your health. As a rule, such phenomena are characteristic of cheap eyeliners and mixers.
• Purpose. Each eyeliner has its own specialty, so to speak. There are products for hot water, cold, as well as universal models. This is indicated by a red or blue braid, respectively. Concerning universal options, then both colors must be present.

Common Problems

Over time, eyeliner can give slack, provoke the appearance of certain problems. There are popular reasons why the device fails:

• Weak or poor-quality braided crimp;
• Low quality connecting elements and components, such as nuts, bushings, fittings;
• Use of rubber and braid materials for low grade hose.

Similar problems, as practice shows, arise when purchasing products from dubious sellers and from unverified manufacturers. But in recent times such situations are becoming less and less.

It's easy enough to explain. Manufacturers, in an effort to win the trust and favor of customers, improve product quality, use the best raw materials. As a result, now most hoses are made of specially treated rubber, nuts and bushings are made of brass, and braids are made of steel, which is not subject to corrosion and is not afraid of water.

Modern fittings have relieved the flexible type of eyeliner from its weak point- seals. Now a number of products do not include seals, since the fitting fully replaces them.

Mounting

Having understood the varieties of flexible eyeliner, determining its strengths and weak sides, you can proceed with the installation.

To do this, follow the step-by-step instructions. At the same time, it is not necessary to involve specialists. The job is simple and can be done in minutes.

• Shut off the water supply. And make sure you turn off both hot and cold water.
• Remove the flexible connection that was used before. It is enough just to dismantle the union nut or fitting, depending on the model of the mixer.
• Purchased flexible hoses are checked for quality, mounted instead of those removed. A seal for the nut on the inlet is not required, since there is a special rubber gasket there.
• Do not overtighten the eyeliner, make sure that the length is enough to avoid tension during operation.
• Screw on the nut, tighten, but do not overdo it. Excessive load may cause breakage.
• Turn on the water and check the new mixer element in operation.

Installation of any fittings to plumbing fixtures is not complete without connecting the device to cold and hot water supply systems. And here an important connecting part is needed - a bellows, rigid or flexible hose for the mixer. These pipes and hoses provide an uninterrupted supply of water to plumbing, so the tap connection must meet the highest quality standards. Which of the three types is better? Go eat a fourth Alternative option? Let's analyze everything in detail.

Types of eyeliner and their features

The connection of the main pipeline to the sink or sink faucet can be carried out using a supply line. There are three types of these elements:

• hard;
• flexible;
• bellows.

Each variety has its own characteristics, design features, rules of installation and operation. Let us consider in more detail the main parameters of each type.

Rigid tube for connection to the faucet

A hard faucet connection is the most durable and reliable option for connecting a water pipe to a plumbing fixture. A tube with a length in the range from 20 to 50 cm can be made from:

• become;
• copper;
• brass.

Any of these materials, be it steel, brass or copper, is able to withstand sudden changes in high and low temperatures, exposure to caustic chemicals for cleaning plumbing, most of the mechanical impact on the tube from the outside.

The advantages of a hard connection are parameters such as:

• long service life - up to 15-20 years;
• high resistance to corrosion processes;
• relatively easy connection.

The rigid water connection is connected to the pipe thread on one side and to the mixer with threaded fittings on the other. For this, special corner valves and other fittings can be used, but in some cases you can do without them.

A threaded connection can be implemented in one of two options:

1. On the one hand, a fitting is connected and union nut with internal thread½ inch.
2. On the other side, a standard M10 faucet thread or a ½ inch union nut with a female thread is connected.

A rigid connection to the tap is recommended for rooms with high sanitary and hygienic requirements, and for those plumbing fixtures where frequent use is expected large quantity people (medical, sports and educational institutions, catering establishments, airports and train stations).

Replacing the external hard type is not difficult. This can easily be done by any man with my own hands with the help of tools that are in every home.

Flexible hose for faucet

This is the most popular option for home faucets, which is a rubber hose that wraps around a metal braid. The flexible faucet hose is favored by millet due to its low cost and simplicity. installation work. Of course, the service life of such a hose is somewhat lower than that of a rigid tube, but if you follow the operating rules, then such an eyeliner will last a long time - up to 10 years.

The duration of operation and reliability of this part depends on the quality of the material for the manufacture of the braid and hose. As a rule, high quality rubber or special non-toxic rubber is used for the manufacture of the hose. The metal braid is made from the finest threads:

• aluminum;
• become;
• galvanized iron.

The braid is necessary for reliable protection rubber hose from the outside from mechanical damage, and from the inside from the consequences of unwanted water hammer, which inevitably occur in any water supply system. So flexible piping should contain the pressure in the network up to 10 atmospheres.

Another significant detail of the flexible connection design is the attachment area. A brass bushing with a union nut is connected to it from one end, and a fitting made of the same material from the other end.

To make the connections airtight, a third element is needed - seals or rubber gaskets.

The length of the flexible hose varies from 30 cm to 2 m.

As already mentioned, flexible liner can last up to 10 years if it is made of quality materials. But twisting during the installation process, kinks, too high temperatures can easily damage the hose, putting it out of action. Therefore, it is worth handling it very carefully, and for the purpose of prevention, change the hose itself every 2-3 years.

Bellows faucet connection

The bellows connection for the mixer is an innovative development, which is a kind of corrugated sleeve made of of stainless steel, at the ends of which are union nuts made of brass. Such a hose is produced using a technology that consists of three stages flowing into each other:

1. Rolling stainless steel tape.
2. Seam welding by laser or arc argon welding.
3. Corrugation of a metal sleeve.

This greatly enhances performance such an underlay.

The bellows product for tap connection is a solution with excellent performance:

• has a high degree of wear resistance;
• is different reliable performance in conditions high temperatures(200-250 degrees);
• withstands sudden changes in temperature;
• long service life - up to 25 years;
• impact resistance chemicals and aggressive environments;
• good resistance to sharp compressions and kinks;
• shows a high level of resistance to oxygen;
• resistance to corrosion processes;
• easy installation process;
• corrugation allows you not to change the flow area of ​​the eyeliner when bending.

But for such high performance have to pay more.

Connecting the bellows hose yourself is very simple:

Which option to choose?

This type of connection is already equipped with standard fittings. different lengths for screwing into the body of the mixing tap. On the other end of the semi-rigid tube, collet adapters are screwed with a rubber gasket around this tube. On the opposite side of the adapter there is a standard (HP or BP) ½ inch plumbing thread.

Connecting a semi-rigid eyeliner is very simple:

1. The bodies of the collet adapters are installed at the outlet of the pipeline.
2. Then you need to screw these semi-rigid tubes into the mixer and install it on the sink.
3. Then you need to bend the eyeliner to the right place so that the tube does not fold, that is, with a large radius.
4. After that, it is necessary to note the required length, put on the conical part of the collet adapters on the tube and saw off the excess.
5. Before sawing, do not forget to put on a collet clamp, otherwise it will take a long time to file the tube and remove a long chamfer from it.
6. Then the tube is inserted into the bodies of the collet adapters screwed to the pipeline in advance.
7. Then you need to throw the conical parts on the adapter, and tighten them very carefully so as not to damage the rubber seals.

For installation, only three tools are required: an adjustable wrench, an open-end wrench from an auto-set and a hacksaw (or a file with a sharp edge).

A semi-rigid eyeliner, unlike a flexible one, does not need to be replaced every couple of years for preventive purposes, while being more resistant to hydraulic shocks and ruptures. By choosing this option, you will significantly increase the reliability of the connection, reducing the risk of rupture or leakage.

General installation rules

Often you have to connect the mixer to the plumbing in the wrong place. But in order to ensure the reliability and uninterrupted supply of water, it is worthwhile to think over the installation details in advance and pick up everything necessary elements structures and tools for connection.

When choosing key parts for connecting a faucet to a water supply, you need to consider the following:

• constructive implementation;
• ease of installation;
• quality of connectors and fittings;
• wear resistance and reliability.

The long service life and stable operation of the mixer depend only on the quality of the product and the correct installation, but also on compliance with certain conditions.

1. Knowing that the quality of the water in our plumbing system is not the best high level, and contains enough a large number of various small particles, dirt and rust, rational decision will mount a strainer at the beginning of the apartment wiring.
2. Before starting the installation, it is necessary to make sure the quality of the piping, checking it for damage, as well as the quality of the crimping of the sleeves and the condition of the threads in the connections.
3. When installing a flexible hose, it is strictly forbidden to sharply bend, twist or break it. The bending radius must be at least 6 times the liner diameter.
4. Do not over-tighten the fitting, otherwise the tightness may be compromised or the fitting may be damaged.
5. After installation is complete, the system must be checked for leaks. If there are no leaks at the joints within 20 minutes, then everything is done well.

Mixer connections are its main hot and cold water. A variety of design solutions for sanitary fittings provide for certain types of piping. In the event that they are not included, you must purchase them yourself.

Correctly selected type of eyeliner, its correct installation, will allow the mixer to work without problems for quite a long time, and the owner will be relieved of the problems of unplanned repairs. There are a huge variety of methods for connecting mixers. Typically, the piping has a single inner diameter, which greatly simplifies their installation.

Flexible hose - an indispensable connecting element when installing plumbing equipment and household appliances. Flexible piping facilitates installation and installation of plumbing and other equipment.

All plumbing equipment is connected to water pipes with rigid or flexible hoses. Rigid hoses are less preferred, as they require more precision in selection and do not allow the device to be moved in any direction. Connecting a flexible hose to a faucet or other plumbing device can be done independently.

What is flexible hose

Flexible eyeliner is a hose protected by a special braid. On one side of the hose there is a crimp sleeve designed to be connected to the mixer. On the other side is a union nut, supplemented rubber gasket. With the help of a nut, the inlet is connected to the outlet.

The supply hose can be made:

• from rubber;
• from rubber.

The rubber hose has bad smell and cannot be used to supply drinking water.

For braiding can be used:

• aluminum. Hoses with an aluminum braid are designed for the passage of water, the temperature of which does not exceed 80ºС. Working pressure no more than 5 atmospheres. Average term product service life is 5 years. Main disadvantage hoses wrapped in aluminum - high susceptibility to corrosion when used in rooms with high humidity;
• stainless steel. The service life of such a product is increased to 10 years. At the same time, flexible piping is able to withstand water temperatures up to 95ºС and pressure up to 10 atmospheres;

• nylon. Nylon braided hose has a long service life (up to 15 years). Installation is possible at water temperature up to 110ºС and pressure up to 20 atmospheres. The cost of such products is higher than other types;

• galvanized wire. The hoses are characterized by high flexibility and low price, but at the same time they have a short service life;
• one-piece corrugated hose (bellows connection). The eyeliner is quite strong and durable. Differs in high cost.

The most common for domestic applications are stainless steel braided hoses.

The choice of eyeliner

If you need to replace the flexible hose, then first of all you need to choose the right hose to connect the mixer. When choosing, you need to rely on the following factors:

• eyeliner assignment. On sale you can find hoses for connecting cold and hot water, as well as universal products. The cold water inlet is wrapped in blue thread. For hot water - a red thread. Universal eyeliner has interspersed with both blue and red threads;

• hose settings. When selecting parameters, it is necessary to determine the type of connection of the supply to the mixer and the water pipe (nut, fitting, and so on), as well as the type and size of the thread. The thread is internal and external. Thread sizes range from ½” to 1 ½”. The next step is to select the length of the hose. To make the connection as reliable as possible, it is necessary to eliminate the possibility of stress on the hose. This requires choosing a device whose length is slightly longer than the distance from the mixer for pipe outlet;

• material for the manufacture of fittings and nuts. Brass is more reliable and durable. Connecting elements can also be made of aluminum (over time, the material becomes rusty and becomes unusable) or plastic (highly susceptible to mechanical stress);
• the hose must be flexible enough. If, when holding the eyeliner at one end, the hose takes a hanging position, then this indicator is normal. If the hose takes horizontal position, then the elasticity index of the product is small;
• there should be no visible damage on the winding, nuts and fittings, which will lead to a reduction in the life of the product.

Based on the presented factors, each user can independently choose the most suitable and durable product.

How to replace an eyeliner

When replacement is needed

The hose needs to be replaced if:

• the flexible hose broke. Breakage of the braid or rupture of the inner hose will lead to leakage and, as a result, flooding of the room. Causes of leakage can be high pressure in the system or mechanical impact;

• a flexible hose leak was detected at the junction with or a water pipe. The reasons for the formation of leakage may be the natural wear of the gasket or a crack on the fitting (nut).

The process of replacing flexible piping

To install a flexible water supply for connecting a mixer, you must:

1. turn off the water supply. This can be done using a crane installed in the apartment;
2. open the taps of the mixer so that the remaining liquid is glassed;
3. using an adjustable wrench or wrench that matches the diameter of the union nut, unscrew the hose from water pipe. If the junction is rusted and the hose does not unscrew, then you should not make an effort to remove the eyeliner. In this case, a solvent or WD 40 liquid is applied to the rust, which removes plaque;

To avoid flooding with water remaining in the hose, it is recommended to substitute a container under the connection points of the wiring.

1. disconnect the hoses from the mixer with an adjustable wrench;
2. connect new connecting hoses to the mixer and install the device in its original place. If the attachment on the hose does not match the connector on the mixers, then adapters are additionally installed. When installing the adapter, it is important to take care of the tightness of the connection, which is equipped with a FUM tape or linen thread;

1. fasten the inlet hoses to the outlet of the water pipe.

It is required to fasten the hoses to the mixer and the outlet without special effort, which can lead to the formation of a crack in the union nut or fitting. Use to seal the connection. additional funds do not, as the eyeliner already contains built-in gaskets.

1. when turning on the water for the first time, it is recommended to check the flexible hose and the connection points for leaks. Average inspection time is 20-30 minutes.

The process of replacing the connecting hoses is shown in the video.

Replacing the flexible eyeliner yourself is not a problem. The main thing is to choose the right hose that meets all the parameters.

Flexible water supply is a device designed to connect mobile and portable household appliances and plumbing to existing water supply lines. This connection method is reliable, easy to install and easy to use. Undeniable advantages flexible eyeliner made it very popular and in demand.

Kinds

Today on the market flexible water supply is presented in two varieties:

• Rubber hose in a metal braid - the simplest and most cheap way connect anything to the water supply system. On the one hand, the flexible water supply has a fitting, and on the other, it has a union nut. The advantage that a rubber flexible water supply has is the price and simplicity, and the disadvantage is the low level of reliability of such devices.
• Bellows flexible water inlet - structurally, such an eyeliner is similar to rubber, but it has one main difference - a corrugated sleeve. In addition, sleeves are welded to the sleeve of such an eyeliner. Due to these design features, the bellows liner is much more durable and reliable than its rubber counterpart. In addition, it has a wider range of operating temperatures and is resistant to wear, compression, fracture and burning.

In Leroy Merlin stores, you can find one and the other type of flexible water pipes, and make right choice among the presented models will help the highly qualified staff of the network. They will tell you what is better to buy - bellows water or rubber - for each specific case.
