At the final stage of sanitary work, it is connected to the water supply system of mixers, shower, wall-mounted toilet and bidet or other equipment. This can be done with a rigid, bellows or flexible liner. The first option is significantly more reliable than the last two, but more laborious, in addition, it requires not only the presence of a specialized tool, and the skills of working with it. Therefore, the bellows and flexible liner (for example, hoses for kitchen mixers with an exhaust or retractable watering can, soul, etc.) in everyday life more practical.

First of all, it is necessary to emphasize that this option of water supply is considered to be budget, but it is quite reliable, subject to properly selected materials and compliance with the connection technology.

In fact, the flexible water lining is a rubber hose (the same as a watering), placed in a tightly fitting braid made of metal threads. Its main purpose is protection against mechanical damage, both external and internal. The latter may occur due to hydraulic impact. In accordance with the norms, such connecting hoses must be calculated for pressure of at least 10 atm.

Below is an example of a mixer compounds for a Christmas tree type for a kitchen sink with flexible hoses (A), used to linner with cold and hot water.

We note that the siphon for the sink is connected to the sewage system with the corresponding flexible lining (B).

Views

These water hoses are the following types:

to connect the mixer of the washbasin, shower and other equipment to hot water. To identify them, red threads are added to the braid ("A" in Fig. 2);
to connect to cold water pipes. In their braid there are threads of blue ("B");
universal, allow connection to the water supply of any type. The braid of such pipes has red and blue labeling ("C").

Fig. 2. Hoses for cold and hot water, as well as universal

In addition, the eyeliner differs according to the material of the braid, which is reflected in certain characteristics, namely:

There are pipes where hoses are not made of rubber, but rubber, such products are more reliable, but also much more expensive.

As an additional protection, the braid can cover the silicone layer, according to manufacturers, it allows you to extend the service life of up to 20 years.

Despite the fact that it is also physically flexible, it is customary to allocate such a type of eyelid as a separate type, due to essential constructive differences. The feature of the bellows linked is that the shell is a metal corrugation, durable, but at the same time flexible, in addition to this inside there is no rubber hose.

It is also worth noting that the fitting together with the terminal lock is connected to the corrugated sleeve welding, it significantly increases the reliability of the structure. The life of products of this type is at least 25 years, while they can be used to work with a technological medium heated to 250 ° C. As a rule, the corrugation is made of stainless steel, but the plumbing of the VIP category is found, where brass and copper are used for this purpose.

This is a new type of eyeliner, and at the moment there was no appearance on the market of non-original products. As for the price, it is significantly higher than conventional connecting hoses.

Connecting hose device

Having understood with the views, consider for a general familiarization of the standard design of flexible eyeliner.

Fig. 7. Design of flexible pipes for mixers

The product consists of the following main elements:

Sealing pads allowing to ensure the tightness of the compound and not allowing the leakage "A".
Brass or steel nipple "B".
Rubber or rubber hose "C".
Aluminum protective braid, stainless steel or nylon "D".
Press sleeve (clamping nipple) "E".
Connecting fitting (steel or brass) "F".
Caid nut "G".

The eyeliner is manufactured with a compound of three types: nut-nut, nut and fitting fitting. Standard sizes for nut - 1/2 ", for fitting - M10. Sometimes there may be a non-standard connection, for example, a M8 fitting or a nut on 3/8 ". In this case, you will need the appropriate adapter to the kitchen mixer or other equipment.

Length of flexible hoses can be from 500 to 2000 mm, we advise you to select the appropriate size so as not to install extension liners.

Note that the fitting can be short and long. The latter is more convenient to connect the mixer.

How to choose a hose for the mixer?

The presence of labels with specified technical characteristics, this will allow you to prevent errors. Make sure the diameter and fastening type matches your equipment.
Be sure to pay attention to the weight of the product if it has an aluminum braid, the hose will be much easier than the one where steel is used (in most cases, such products and dubious quality fitting). As practice shows, they quickly fail, literally, for six months, and even before.
An applying should be abandoned if it is equipped with a plastic fitting, such a mount is not designed for the load required for household purposes.
In the event that the hose has insufficient flexibility, it should not be purchased, since such a sign indicates poor quality. As a rule, because of this, several microcracks arise on the braid, which can cause deformation.
Pay attention to the press of the sleeve, the stainless steel should be used as the material for them. It is important that their tubes are tightly kept - this is an indicator of high-quality sending.
Check out the execution of cape nuts if they are very thin or lungs, it means that this is a low-quality product, and when it is used, the high probability of problems occurred.
Poor-quality rubber has a sharp characteristic smell, finding such, refuse this model, since such material will begin to leak pretty quickly.
Selecting the hoses for hot water, do not make mistakes with color marking, they must be with a red or red-blue thread, do not fit with blue.
Select the applying of the appropriate length is undesirable so that it sags or was a latitude.
Many brand devices (for example, Damixa or Hansgrohe) are included in 50 centimeter hoses. To connect the mixer in the kitchen, the length is enough, but to connect other equipment, they may turn out to be short, for example, a standard placement over a bathroom 150 cm. In this case, you can remove them and fasten the supply of the desired length or use it as an extension. The last option is not quite successful. This is due to the fact that in the elongated hose there will be an unnecessary compound, and therefore reliability will decrease.
What product choose, imported or domestic production, does not matter much, we note that our products are sometimes better and reliable foreign ones.

How to change the hose on the mixer - step by step instructions

Suppose we are faced with the task to change in the kitchen or in the bathroom mixer GROHE, all the necessary plumbing equipment has already been purchased. From the tools for this purpose you will need a gas key (you may need two pieces) and Fuma Ribbon.

We tell how to replace the GROHE mixer, this is done according to the following algorithm:

Blind water supply. If this does not make it necessary to repair, both from your neighbors from below.
An old device is neatly pulled out, for this it is necessary to unscrew the eyeliner from the kitchen mixer. Do not apply a lot of effort so as not to damage the thread.
If the mixer for the sink is mounted, fix it on it (for the bath is mounted on special racks). We note that some branded mixers have a special nozzle with a grid playing the role of the filter, do not forget to install it before turning the eyeliner.
We wake on the thread FUM tape, after which the underwater hoses should be tightened.
If a mixer is installed for a bath or a kitchen with a stretching watering can, then screw the adapter to the vigilance and connect to it that is included in the hose (for watering can). Wherever there is a thread, we use Fumu Ribe.
At the final stage, we turn on the water supply and check each hose for the mixer so that nothing else appears anywhere. If everything is in order, it means that the installation can be considered successfully completed. Otherwise, it is necessary to close the water supply cranes and check the connections. It is possible that water flows due to the fact that rubber seals on the eyeliner hose are not installed ("A" in Fig. 7) or an insufficient layer of FMU ribbons on the thread. You will need to disassemble the connections (disconnect the eyeliner) and check, correct the error and spin the connection.

If it is required to connect a flexible liner of household plumbing (ordinary or embedded type), a bidet with a separate supply, a mortise tank for toilet bowl, etc., it is done on the same principle as the replacement (skipping point where the old mixer is unscrewed).

And in the bathroom, given the fact that sanitary ware services are expensive, and the conduct of this operation is technically simple and does not require any skills. When installing a new plumbing device, it is usually necessary to throw away the old hose for the mixer in the kitchen, which over time or after dismantling often loses hermetically loss.

When choosing a new flexible eyeliner, we consider several types of products presented in the market, each of them has its own advantages and disadvantages. To make an optimal solution, it is necessary to study the peculiarities of each type of sleeveless for water supply, familiarize themselves with consumer reviews and products of well-proven producers in the manufacturers market, take into account the convenience of mounting.

The overwhelming number of the market presented in the market has standard inlets to bring cold and hot water with a sliced \u200b\u200binternal thread with a diameter of 10 mm. To connect to the mixer, the liner is equipped with a M10 threaded fitting (height of the threaded crest 10 mm), and at its opposite end is located.

An American includes a naked nut, placed on an extended (fragrant) end of the sleeve, and a sealing gasket. When screwing the nut on the rolling pipe threads, the ring seal is compressed and ensures the tightness of the connection.

The standard inner diameter of the cape nut for connecting the kitchen mixer to the water supply pipes is 1/2 inches (15 mm), there are other less popular sizes of nuts - 3/4, 1, 1 1/2, 1 1/4, 2, 2 1 /2 inches.

Not every hose for mixers in the kitchen has a threaded nipple for connecting to the plumbing. Some expensive models from the world's leading manufacturers with high poles and inner wages (German companies Grohe, Hansgrohe, Blanco, Czech Lemark) are connected without threading snaps.

Braid Sleeves - Device

Flexible hoses in braid

The most popular and budget type of eyeliner. It is an elastic rubber tube, placed on both sides in a Christmas tree sleeve and protected from above metal braid. The rubber shell (inner diameter is 8.5 mm) is reliably pressed against the fitters with pressed crimping sleeves, ensuring a durable, hermetic and unintended connection.

In addition to conventional rubber, tubes from modern elastic material EPDM - produced by the chemical method of the elastomer, which is peroxidically crosslinked ethylene-propylene-deyne-rubber. Due to its high physicochemical parameters (resistance to a wide range of temperatures and neutrality to most aggressive chemicals), the EPDM tube provides a long service life of the entire product.

The outer sheath of the sleeves is thin woven threads, the main material of the manufacture of which is aluminum or more expensive stainless steel, is much less common to be cheap galvanized steel.

Crimping sleeves in high-quality eyeliner are made from plastic and durable AISI 304 stainless steel, a fitting and a nickel nut - from nickel-plated brass (UNI EN 12165 CW617N brands, UNI EN 12165 CW617N), in cheaper types of AISI 304 stainless steel, sealing rings and gasket - From EPDM.

A flexible cladding in the braid can be calculated for the supply of cold or hot water only (individual threads have a blue or red color), but universal sleeves with red and blue marking are most often used in everyday life.

A large number of sleeves are found on the market in the braid of domestic, Chinese and European production, which have a significant difference as a manufacturer, on which the service life and physicochemical parameters depends. Therefore, when considering technical specifications, these factors should be taken into account, the main features of the cladding in the braid:

The working pressure in products from high-quality rubber and stainless steel shell is 10 bar, the maximum can reach up to 20 bar, in budget varieties, these indicators are lower on average twice - respectively, 5 and 10 bar.
Range of working temperatures of products - from 1 to 90 ° C at maximum up to 100 ° C.
The lifespan of the sleeve depends on the quality of the manufacture of the hose and its cost, the budget species of its average is 5 years old, in expensive 10 or more.

Due to the elastic inner tube and outdoor reinforcement, the eyeliner can be bent with the smallest radius, while the more budget product in the aluminum shell is plastic and softer than with stainless reinforcement.
The eyeliner easily connects to the mixing device using the key, at the beginning of the fitting is screwed to the housing (for convenience of connecting it different lengths), then it is fixed to the pipeline using a naked American fitting nut.
In the market there are reinforced expensive models from foreign manufacturers, having a polymer (nylon, polyethylene) braid or two layers of metal and synthetics. Such a sleeve is withstanding the pressure of 20 bar (on a gap of 80 bar) and has an average operational period of 15 years.
The main advantage of flexible storm with metallic reinforcement is the price accessibility, they are referred to budget products.
We include a satisfactory reliability of their inner rubber tube to disadvantages with braid - over time, it loses its elasticity, becomes fragile, cracks appear on the shell and the sleeve begins to leak.

Polymer

Watering for water from polymeric materials (stitched polyethylene, silicone, polyvinyl chloride) is often used in shower systems to attach the leek, unlike analogs in a metal corrugation, they do not scratch the surface of plumbing equipment - ,. To increase the strength inside the polymer tubes, a metal spiral or hard cord from synthetic yarns is often located.

To connect mixing devices, polymer hoses use much less often and usually in models for kitchens from foreign European manufacturers. Polymer liners have high temperature (up to 100 ° C) and pressure (operating pressure up to 20 bar) characteristics, long service life for at least 15 years.

Silphon hoses

The bellows are called corrugated (compressed in the transverse direction) thin-walled 0.3 mm stainless steel pipe (AISI 304 brands) with connective fittings on the edges. In appearance, the bellows is similar to a hose for a kitchen mixer equipped with a retractable watering can. However, the latter has a completely different design - its outer shell is made of spiral-back stainless steel (similar design in shower slabs), inside of which there is an elastic pipe from rubber or silicone.

To connect to the mixer of the corrugation, it is equipped with a bustzer with sealing rings on one side and an American-type cape type with another. The pressed fitting is performed from a stainless steel or brass, like an American anticipant nut, which is held on the collapsed pipe end.

The bellows of the corrugation has the following features:

The service life of high-quality stainless steel is quite high, for the bellows liner, its average value is 25 years.
It is clear that the stainless steel withstands considerable temperatures for thin-walled metal, the working value is about 250 ° C.
The bellows tube has high strength, with its help you can bring water with a working pressure of 16 atmospheres with a maximum indicator to 50 atmospheres.
The stainless steel is an environmentally friendly material, so safe for a person when using drinking water supply in highways.
When bending, the corrugated surface of the sleeve prevents the change in the cross section of its shell, that is, it cannot be blocked as a flexible polymer with a complete overlapping of the passage channel.
The bellows corrugated corrugated vibration in the system and resistant to hydrowards, prevents salting deposition.
The bellows are not too convenient when connected in a limited space - it is less flexible than polymer hoses in the braid and without it, has a large radius of rounding.
Also, the flaws of the bellows include a slightly higher price than the analogs in the braid.

Hard liners - varieties

Hard

Sometimes the kitchen sink is suspended on the walls and does not have the cabinets under him, in this case the ordinary eyeliner does not look too aesthetic. To give the appearance of the style and increasing its decorativeness, it is sometimes used by a hard eyeliner having the following varieties.

Metal hoses

This type is usually used in expensive imported mixers, there is no thread in them for connecting to the crane, and the second end is connected to the pipes using an American. Materials of metallic sawmilling are corrosion-resistant compounds - chrome or colored brass, stainless steel, copper, bronze.

Fittings for connecting polymer pipes

Some plumbers prefer a reliable and hard method of connecting the mixer using pipes from a metal-plastic if they were supplied to water in the whole house or apartment. To carry out this option, the connection in the trading network is implemented special with fittings for attaching to the mixer housing - one straight line, and the second is bent at some angle. After screwing the adapters, they are connected to the metal plastic pipe and clamp it with a compression nut.

How to choose a hose

Choosing a hose for a mixer installed in the kitchen, are guided by the following considerations:

The eyeliner should be connected to plumbing devices without any additional adapters if all fittings for connecting and holes in the cranes have one standard size, the diameter of the water pipes may differ. In this case, picks up the hose for the mixer, which has the sizes of the cape nut in diameter not 15 mm, and 20 (3/4 "), 25 (1"), or 32 (1/4 ") mm up to 2 meters long .
The color marking of the hose indicates the scope of the application, yellow means a prescription for gas supply, blue and red - to sum up the cold and hot water, respectively. Usually acquire a universal hose for the tap in the kitchen, calculated on the flow of both cold and hot water.
The length of the selected hose should provide it freely susceptible position without tension and twist.
The most popular with the consumer, due to low cost and flexibility, use rubber hoses in the reinforced braid from metals. To choose a high-quality hose in a stainless steel shell, which is difficult to distinguish from aluminum, it is weighed on the hand and bend - such a product weighs more and less flexible than the budget analog.

The quality of the inner rubber hose can be determined by the smell - sharp discharges indicate technical rubber and low cost of materials used.
A nut type American should have sufficient thickness and length for a reliable threaded connection to pipes, the preferred material of its manufacture - chrome brass.
It is better that the threaded liner fittings that screw in the mixer had two rubber rings, at least one of them should be inside the threaded channel. Some hoses have a fitting with one sealing ring on the edge - if in the mixer weaving the water threaded nests are not deep enough, the seal will not fall into the connection site and the eyeliner will give to flow.
Acquire all types of eyeliner better in specialized outlets that have documents for goods and quality certificates. Especially should be attentive when buying the bitter species - often they are released from poor-quality stainless steel with low chromium content, which rusts after one or two years of operation and gives leak.

Installation

For mounting, eyeliner does not require any expensive tools, spare parts and seals. There is enough one of the adjustable key and the horn by 10 mm to connect the fittings to the crane case.

To connect the hose to the mixer, perform the following sequence of operations:

Fully remove the old mixing device from the sink, unscrewing the hoses from the water supply pipes.
Connect the liner to the mixing case.

To facilitate the work, prevent the formation of a lime flush on the thread and in the future it is easy to unscrew the hoses from the kitchen mixer when replacing it, additionally use any kind of machinery or technical oil. The fittings are covered with lubricant and screw into the threaded holes of the case, slightly pressing the half-turn of the flat key.

The body of the crane in the sink's seat hole along with the hoses and fix it from below, depending on the design of a precipitant nut or plate on the heel.
Wash the carving of water pipes and screw the naughty nuts of hot and cold water onto the ends, slightly pressing them with the key to the half-turn.
Include cold and hot water with a rotation of the cartridge handle and are convinced that the water supply adjustment is performed with the usual arms. If you bring the cold and hot water in places, turn off it in the apartment or cranes under the sink, change the hoses in some places, twisting them on the pipes.
Include water and check the eyeliner for leakage, using a piece of dry white tissue for this. It is carried out on a braid from top to bottom, if the water drips, press the fittings or cape nuts on the pipes.

The most popular in the consumer enjoys a flexible watering of water for mixers with a metal braid - its low cost fully justifies the service life of 10 or more years. The remaining types of expensive bellows and hard eyeliner during their reliability do not always provide the convenience of connecting in a limited space or complex for installation with their own hands.
