Many people are familiar with the situation - the flexible hose on the faucet or toilet cistern burst, and all the floors below are flooded.
Unfortunately, the problem is quite common, so today I want to touch on this topic in detail.
Let's remember where it began.
There has always been a need for flexible hoses. Many minds were haunted by the thought of how to make the installer’s work easier and speed it up, and as always, “foreign” manufacturers were the first to think about this, while domestic ones stubbornly produced the “herringbone” mixer, which can be safely described as: “well, , try to connect!
Eyeliners, as in the photo, 
so familiar to us today, in fact, appeared literally in the last decade, having previously undergone a number of changes - at first a copper tube with union nuts, flared at the ends, was produced. For me this is ideal reliable option, but from the point of view of achieving maximum flexibility, it left much to be desired. 
The “minds” strained themselves and developed plastic ones, the principle is the same, but they also equipped them with plastic nuts, they proved to be disgusting - they burst on the body. As a result, they were equipped with brass nuts, and the material was improved. 
As a rule, such connections were used during government construction, and only when connecting cold water supply to flush cisterns toilet, ours craftsmen, having obtained this miracle through “pull” (it was impossible to find it in stores), they easily installed it in hot water, and since the material was not designed to work at high temperatures, accidents often occurred.
Having realized this, the “craftsmen” went further - they began to use oxygen hoses, pressing clamps onto brass fittings. The fittings were sharpened on factory machines, in the quiet of the authorities. One might say that the matter was put on stream; it was possible to purchase this fitting on the market with necessary thread(external, internal, proper diameter). At the same time, another type of flexible connection appeared - a high-pressure hose used in hydraulic installations Believe it or not, people managed to assemble all the wiring around their apartment (house) from such hoses, although there were difficulties connecting the union nuts with pipe threads. 
The fact is that the threads here were metric, and connections had to be made through specially machined adapters. This material was highly durable, but the downside was technical rubber, so the water coming out of the tap had an unpleasant smell.
The next step as a flexible eyeliner was to use metal plastic pipes. I note that this material received very wide application until the water supply is completely replaced with it, eliminating the ferrous metal, but that’s not what we’re talking about today.
Conditions and rules for installing flexible hoses.
So, we came to the eyeliner that we see everywhere today. It is universal, that is, it is used for both cold and hot water supply. It consists of a rubber hose inside and a metal braid on the outside, produced in various lengths - from 15 centimeters to 2 meters. Ends with union nuts or fittings with external thread, various diameters.
But…
1. Initially, this device was intended as a connection water pipes with plumbing fixtures, nothing more, but inventive guys, in order to save money and not overwork themselves, make almost all the wiring, and let’s be honest - all of it! ...I've seen enough.
Make no mistake!
Assurances about performance for 5 or even 10 years are a marketing ploy by manufacturers, and the indicated figure on the tag is just a figment of wild imagination. There is also a statement about insurance of the eyeliner! Honestly? — I have not heard of cases of compensation for losses!
2. The material used in the production of the hoses is absolutely identical; accordingly, the service life in cold and hot water supply is sharply different.
3. The service life depends solely on the characteristics of the line, that is, as indicated above, on the temperature, plus the pressure in the system. We understand, right? There is a system with pressure not exceeding 2.5 - 3 points, and there is 7 and higher.
4. The thickness of the hose wall is no more than 1 millimeter.
5. In addition to the above, it is very important to follow the installation rules:
a) installation by tension is not permissible;
b) when tightening the nut, it is not permissible for the hose to twist after it;
c) if it is necessary to make a ring, then the ring should be as large as possible in diameter.
The mixer comes with instructions indicating the rules for connecting the flexible hose, and it also contains a diagram. 
The following picture is an emergency situation: 
This is the trend in our construction. “Foreign” manufacturers happily supply their plumbing fixtures with these connections, but during installation they often use only the following connection: 
Flexible eyeliner on the verge of failure.
This begs the question: - Why not put it?
Bet! Just don’t be lazy to monitor the water supply system, periodically pay attention to the condition, visually and by feeling.
1. If protruding “hairs” of wire appear on the flexible eyeliner, then this is a harbinger of an accident, because if it sticks out, then the same thing happens inside the braid.
2. If they become noticeable brown spots, this means that microcracks have appeared in the rubber hose, which means that a burst will occur.
Pay attention to the water supply of your home and avoid a lot of troubles.
3. When leaving your home for a long period of time, turn off the water supply, use the taps at the inlet for this. If you trust one of your neighbors, leave the keys to your apartment in case of an accident.

A flexible water hose is used to connect the toilet and faucet to the water pipes. Experts recommend choosing eyeliner according to certain parameters, each of which has its own meaning. Read on to learn how to choose and install the hose correctly.
How to choose a hose
- type of hose;
- purpose of eyeliner;
- eyeliner sizes;
- hose connection methods.
Types of flexible water hoses
The main types of hoses used to connect water are:
- reinforced liner. The device is a rubber hose, which is reinforced with metal threads for additional strength. The following can be used as braiding threads: stainless steel, nylon, aluminum;
The most durable are liners reinforced with nylon and stainless steel. The devices can be used to supply water with a maximum temperature of 95ºC at a pressure of up to 20 atm.
- bellows liner. Flexible corrugated hose made entirely of stainless steel. The bellows liner is designed for the passage of water with temperatures up to 250ºС. Thanks to its operating parameters, the hose can be used not only in the plumbing system, but also in.
Types of water hoses differ not only in performance, but also in cost. Reinforced eyeliner can be purchased at a price of 150 - 250 rubles, and a bellows liner for 400 - 500 rubles.
Separation of eyeliners according to purpose
According to their purpose, all water supply connections are divided into devices intended for:
- connections cold water;
- connections hot water.
The hot water hose is distinguished by the presence of a red thread in the braid, and the cold water connection is marked with a blue thread.
The most commonly found on sale is a universal cold and hot water hose. You can visually identify the device by the presence of both red and blue threads in the braid.
In a public water supply system, cold water quite often gets into hot water supply pipes and vice versa. To avoid problems with plumbing connections and extend the life of the hose, experts recommend using exclusively universal hoses.
Flexible Hose Sizing
The next step in choosing a water hose is to determine its overall dimensions. To find out the dimensions of the hose, you need to calculate:
- liner diameter;
- liner length.
The diameter of the hose is determined based on the throughput. A thin water hose is intended for plumbing fixtures that do not require quick filling, and vice versa. In order not to calculate the parameter yourself, you can use the average data presented in the table.
The length of the metal braided hose is determined by the following parameters:
- the distance between and the connected plumbing product (determined using a tape measure);
- hose installation rules that must be followed to increase the service life of the product.
Basic criteria for determining hose length
Defining connection methods
The water supply hose can be supplied with in various ways connections. The following are used as connecting elements:
- a nut designed to attach to an external thread;
- thread that connects to the internal thread;
- fitting, primarily used for connecting to a mixer.
To determine which connection methods are used in the system, it is necessary to inspect the plumbing product and the outlet from the water pipe.
In addition to determining the connection method, it is also necessary to clarify the size of the thread or fitting.
How to install a flexible hose with your own hands
Basic rules for connection
Before you begin installing flexible hoses, you need to know the basic rules for connecting the device, which are as follows:
- It is not recommended to use eyeliner whose braid is broken;
- Do not install a hose whose connecting sleeve is not subject to visual inspection;
- Do not strain the hose during installation. The liner should be installed freely, but without unnecessary kinks;
- If you need to connect the hose from the side, you should pay attention to the bend area. Twisting the liner along the longitudinal axis is prohibited;
- to reduce kinks, you can use special adapters that allow you to reduce the radius;
- if during the installation process it is necessary to arrange a bend in the hose, then a minimum radius of 70 mm must be observed;
- length cannot be increased flexible hose by connecting to another liner.
DIY installation
To connect a water hose you will need:
- wrench or adjustable wrench;
- FUM tape (tow), which allows you to seal the connection.
To replace the water hose for the faucet, you must:
- turn off the water supply to the plumbing fixture;
- remove the eyeliner that has become unusable. To do this, use a wrench (adjustable) of a certain diameter;
- Sealing material is wound onto the new liner. Each liner must be equipped with rubber gaskets, but in most cases it is not possible to achieve complete sealing solely with the O-rings included in the kit;
- the hose connects to (the toilet);
- the liner is connected to the outlet of the water pipe.
It is not recommended to overtighten the threads as connecting element may burst, which will lead to the need to purchase a new hose. It is considered optimal if you tighten the thread by hand and tighten it with a wrench by ¼ of a full turn.
The method of connecting the water supply to the kitchen faucet is shown in the video.
The correct choice of water hose and compliance with all standards for connecting the device are the key to long term product services. If at least one factor does not correspond established standards, then the line can go out of working condition at any time, even with minimal pressure in the system.
Until recently, most plumbing systems in apartments and private houses were made according to the same scheme. Initially, steel or plastic pipes were laid out in the kitchen, bathroom and toilet to the installation site of the end users. At the second stage, all consumers - washbasin, sink, washing machine, shower and waste tank were connected using a flexible water supply, or in common parlance - a water supply adapter hose.
Main types of flexible hoses
The use of flexible transition hoses is a necessary measure. Just twenty years ago, all taps and tanks were connected directly to a steel water pipe using a cunning system of taps and couplings. As a result, the number of pipes in the bathroom and kitchen often resembled the insides of a submarine. But that's not the worst thing.
Due to periodic vibrations and hydraulic shocks, the connections and seals of the water supply system regularly failed, and the delicate rubber gaskets and valves on the drain tanks were destroyed within a few months. The problem was solved using a flexible nut-nut water line. Thanks to high technical specifications flexible water connection service life shut-off valves managed to extend from several months to 10-15 years.
Today at household Three types of flexible hoses are used for water supply:
- Rubber tubes in steel braiding. It is easily distinguished by its prickly outer surface, consisting of dozens of intertwined thin wires;
- Hoses made of special rubber in a braided plastic sheath. They are mainly used for supplying water to the washing machine;
- Bellows flexible water connection made of stainless steel. Manufactured by pressing and welding high pressure hundreds of steel rings assembled on a core mold. The result is a relatively flexible and very durable stainless steel connection.
Important! All water hoses for water supply they are designed for high pressure, so the outer shell is always made of either reinforced steel-plastic braiding or stainless steel.
A bellows flexible stainless steel water line must be distinguished from a similar extension or hose for a handheld shower head, which is not designed for high pressure. It is quite simple to distinguish an extension cord from a bellows - all flexible hoses for supplying water, no matter whether steel or plastic braided, are equipped with hex nuts or fittings for spanner. In the extension for a manual shower head, round rounds are installed at the ends. union nuts with corrugated surface. They are designed for low pressure, so they are tightened by hand, without using a key.
The exception is some models of flexible hoses in nylon braid for supplying water to washing machines. Such devices are used as a flexible supply for hot water, are designed for high pressure in the hot water supply system and are equipped with plastic nuts, not turnkey, but with wings for tightening by hand.
Materials for flexible hoses
Water circulates under relatively high pressure in the pipes and communications throughout the apartment. For example, for water pipes, water pressure can reach 5-6 atm, hot water in the heat exchanger and system pipes individual heating is under a pressure of 1.5-2 atm, in centralized hot water supply systems the pressure reaches 3-4 atm. Therefore, the strength and durability of flexible liner primarily depends on several conditions:
- The quality of the rubber or metal from which the central channel of the hose is made;
- Material used for reinforcing braid;
- Metal used to make fittings and nuts.
How important is correct selection braid material can be assessed according to the technical characteristics given in the table.
The central part of the flexible hose is made of special types of rubber with a minimum content of water-soluble components. The material must comply with GOST 5496 for flexible water supply. Most often, hose manufacturers use EPDM grade rubber.
For your information! The most common defect is damage to the outer braid of the flexible hose and the compression ring or sleeve securing the nut at the end of the rubber hose.
If you need to make a decision on the question of which flexible water connection is better, choose a hose with braided stainless steel AISI 304 or GOST 5632. For fittings or nuts the best material there will be brass CW614N, with nickel plated. In this case, the service life of the flexible water line will be at least 10 years. Hoses with aluminum or steel-aluminum fittings last half or three times less.
Designs of flexible water hoses
Almost all flexible hoses used to connect water consumers in the home can be divided into two groups:
- Extension cords used to supply water to remotely located plumbing fixtures, washbasins, bathtubs, and shower stalls. Usually these are long hoses, from 90 cm to 500 cm, a standard set of flexible water connections, a ¾-inch fitting and a nut;
- Adapter hoses, usually of short length, up to 50-60 cm, are used to directly connect the consumer to the water supply system.
When selecting extension cords or flexible leads, you must pay attention to the markings applied to the outer braid in the form of colored stripes. Hoses for cold water are marked with blue stripes, for hot water - with red markers. Similar by appearance Extension cords with yellow stripes are used only for gas connections; they cannot be used for water.
Features of the design of flexible rubber hoses in steel braiding
Most often, flexible braided hoses are used to connect plumbing fixtures, kitchen and shower faucets. The advantage of rubber-reinforced extension cords is their low price and relatively high flexibility hose material. You can freely bend it into a ring, but you cannot bend it in half, stretch it, or try to tie it in a knot; such handling invariably leads to damage to the crimp sleeve and braid.
Water heaters for shower cabins and cisterns, as a rule, are connected with a flexible water supply of 1/2 inch.
Most often, a hose with a fitting and a nut at the ends is used, but manufacturers also produce models in “nut-to-nut” and “fitting-to-fitting” designs.
Flexible hoses of a special configuration are used for mixers and kitchen taps. They are smaller in diameter than a conventional extension; the cross-section of the internal channel is only 6 mm. An M10 fitting is pressed into the hose at one end; it is screwed into the body of the joystick or mixer at the sink. It must be placed under the thread of the fitting rubber gasket, so the fitting can be screwed into the faucet hole without any sealing tape.
At the second end of the line there is a half-inch nut with which the faucet is connected to the fitting on the water supply system pipe. A silicone gasket is placed inside the nut, but this, as a rule, is not enough to ensure a tight seal, so before installation the threads are wound with a foam tool.
Most faucet manufacturers complete their products with a set of two hoses 50-60 cm long. As a rule, when you buy a good quality faucet, you automatically receive excellent connecting flexible hoses as a bonus. Each one must be marked: for cold water - in blue, for hot water - with a red or blue-red marker.
Today you can buy flexible eyeliner produced by the companies Aqualine and Monolit, which are famous for good quality Italian VALTEC, Spanish TUCAI or IndustriasMateu.
In order for the flexible eyeliner to serve the period promised by the manufacturer, it is extremely important to adhere to the recommendations set out in the product data sheet:
- Do not install a flexible hose with a bend radius of less than 50 mm on a rubber surface in this condition, even in ideal conditions operation, cracks and fistulas invariably form;
- The connected supply must have sag or slack. Most often, when connecting, hoses of increased length are used, which are rolled into an arc or ring of a relatively large radius, 15-20 cm;
- When wrapping sealing tape around a water line outlet fitting, it is important not to exceed the recommended thickness of the seal. Otherwise, when tightening the nut, the thin-walled brass part may crack.
If the rules are followed, a high-quality rubber hose can withstand a maximum pressure of up to 20 atm. To make it easier to connect extensions and mixing hoses, large number adapters and nozzles, if desired, you can assemble the entire home plumbing system from extension cords and adapters. True, it will have to be changed every 7-10 years.
Water supply using a stainless steel hose
Most often, stainless steel hoses are used for remote water distribution, instead of the usual steel or plastic pipes. Using a flexible 1-inch water extension, you can bring water into the apartment from the central water supply riser. Often, additional radiators of the heating system are connected with stainless steel bellows. Due to the corrugated surface, the resistance to water flow is higher, but this can be easily compensated for by using oversized hoses.
Corrugated pipes are also used to connect boilers or hydraulic accumulators, pumps, filters, and any equipment that requires increased strength and at the same time capable of dampening the resulting vibrations.
Union nuts are made of brass; branded models always have a nickel coating and a manufacturer's mark. An important distinguishing property of bellows is their high resistance to water quality. The corrugated surface can accumulate rust or organic matter, but stainless steel almost never corrodes, even when the water is highly saturated with carbonate salts. Rubber connections quickly fail in very hard water conditions.
Conclusion
The most significant problem with flexible hoses is huge amount counterfeits sold on the market and in salons under the guise famous brands. Such hoses are manufactured on semi-industrial equipment using cheap materials, so the rubber can produce a characteristic chemical smell, separate and dissolve in water. Metal parts quickly oxidize, the nickel plating peels off, and the stainless steel bellows becomes covered with a thick layer of rust. Therefore, experts say that it is easier to install a flexible eyeliner than to choose an inexpensive and at the same time high-quality specimen.
Features of flexible water line
When planning a system home water supply and gasification today are increasingly using newfangled and convenient devices. For example, to connect a washing machine or dishwasher, boiler, toilet, as well as appliances that use water, no longer need to be fastened together steel pipes clamps, forming a whole bulky metal structure. It is enough to use flexible water connections, which will greatly simplify the entire system. At the same time flexible pipes easy to connect to plumbing and gas equipment, high quality and reliable in operation.
Flexible eyeliner for water is a movable hose of various lengths, which can vary from 30 centimeters to 5 meters. At the ends on both sides of the hose there are fittings or nuts with rubber gaskets.
Advantages of flexible water supply:
- Compactness and non-bulky nature are the main advantages of flexible hoses. As a result, space is saved when connecting a toilet, sink, or bathtub to the water supply.
- Flexibility - Connected to washing machine the hose allows you to move it towards the wall or to the side.
- No need to use welding when connecting. It is enough just to tightly screw the nut of the flexible line, not forgetting to install the rubber or silicone seal.
- It is quite possible to connect the flexible hose yourself.
- High practicality and external aesthetics of flexible eyeliners.
- Resistant to water hammer.
- Reliability in operation.
- Durability - some types of flexible eyeliners can last for half a century.
- Flexible hoses are resistant to vibration and minor damage.
In production they are made from various materials. Water connections are made from stainless steel and also with aluminum braiding; gas connections are made from polymers.
Requirements for flexible water connections:
- The main requirement is tightness. At correct fastening flexible hose to the plumbing, it should not allow water to pass through.
- The sealing gasket at the ends of the hose must be made of quality materials.
- The thread on the nut must not be damaged.
- A rubber seal is required.
According to their classification, flexible water lines are divided into the following types:
- bellows;
- reinforced;
- made of stainless steel.
Bellows flexible water line
The bellows flexible water connection is made of stainless steel. The diameter ranges from 12 mm to 34. And the length is up to 200 centimeters. During installation, the corrugated steel sleeve is stretched to the required length. There is a gasket on a brass nut with a high melting point. It is worth noting that low-quality brass can oxidize from moisture, so it is better to buy hoses from trusted brands.
The flexible bellows water line is resistant to high temperatures, withstands from - 50 to + 250 degrees. Due to this property, it is most often used for connection to a central heating system. Bellows flexible water line is not cheap. Its price varies from 200 to 500 rubles. The cost also depends on its size.
The bellows liner made of stainless steel is very durable, its service life can reach 25 years or more. Corrugated bellows connections are used for both water supply systems and gasification.
Advantages of bellows flexible water line:
- made of high quality steel;
- resistant to water hammer;
- durable;
- not afraid of low ambient temperatures;
- hygienic and safe for health;
- does not burn;
- Can withstand water temperatures up to 250 degrees.
Flaws:
- high price.
Reinforced flexible water line
Reinforced water liner is one of the most commonly used types of liner. It is made of rubber braided with stainless steel. Maximum temperature the working fluid that the hose passes through is 90 degrees. Ideal for attaching to a boiler, toilet, washing machine, and flexible reinforced hoses are often purchased specifically for these purposes. Rubber hoses of different lengths are wrapped with red and stainless steel. blue colors. Nuts or fittings with threads and seals are attached to the two ends of the hose. It is not suitable for a heating system, as it will not withstand too high temperatures. The price of a flexible reinforced rubber liner for water is much lower than a bellows liner. But such flexible hoses wear out much faster.
The guaranteed shelf life of the reinforced water line is 2 years. But with proper use it can last longer.
Advantages of reinforced water line:
- environmental friendliness;
- speed of installation;
- ease of installation;
- made of durable materials;
- flexibility.
Flaws:
- with frequent bending, the metal braid wears out;
- rapid wear of rubber upon contact with water.
Flexible stainless steel water line
The connecting flexible hose must be made of stainless materials that are not subject to corrosion. The durability and quality of work of flexible hoses directly depends on this. The price of a flexible stainless steel water line is quite reasonable. Due to this this type flexible hoses are very common among consumers. The length of such a water line ranges from 500 cm to 1 meter.
When choosing a flexible stainless steel hose for water, it is important not to confuse it with a flexible stainless steel hose for gas equipment. Gas lines are absolutely not suitable for connecting to plumbing, as they can rust and leak. The question immediately arises: how can stainless hoses rust? The answer is simple: for gas equipment on stainless steel connections, the tips, that is, fittings or nuts, are made of ordinary steel. Therefore, when using flexible gas hoses for water supply, they will soon rust and begin to leak water. The shelf life is quite long, but rubber gaskets may wear out over time.
Advantages of a flexible stainless steel water line:
- the material from which the supply hose is made is resistant to corrosion;
- low price;
- fire resistance;
- not afraid of sub-zero temperatures;
- ease of installation.
Flaws:
- If the fastening is weak, as well as poor-quality gasket on the thread, the flexible hot water supply may leak at the fastening point.
Before attaching a flexible hose to a faucet, toilet, washing machine, or heating system, it is important to check it for damage to the hose itself, threads, or possible manufacturing defects. The radius of fastening should be no more than 0.4 Nm. During installation, it is important that the hose is not twisted. After attaching the flexible hose, you must immediately check it throughput. The hose must not leak. If drops appear at the attachment point, it must be tightened.
It is important to attach the flexible water line in such a way that it can be conveniently accessed for preventive inspection of the fastening or if it begins to leak after the expiration date.
No one is immune from purchasing low-quality material. Therefore, it is necessary to make purchases with the appropriate certificates, in specialized and trusted stores.
For each individual case, one or another flexible eyeliner will be useful. Basically, each of the flexible hose options is suitable for installation in a home water supply system. Durable flexible water lines are made from quality materials. Naturally, their cost depends on this.
You can buy a flexible water line in any store or online store that sells appliances, plumbing fixtures or all sorts of small things needed in the household.
All flexible hoses are made of non-toxic rubber with a fairly wide range operating temperature, this makes it possible to use them for supplying both hot and cold water. The fittings for cold water are equipped with a blue thread, for hot water - red. These products are very popular in our store; they are reliable and durable. The hose is resistant to sediment formation on inner surface and tolerates mechanical loads and high temperatures well. Installation does not require the use of special expensive tools.
Advantages of using a flexible water line:
Allows you to freely change the location of household appliances; allows you to move devices without changing pipelines; convenient in small rooms where it is impossible to install a pipeline; it can be hidden behind appliances; indispensable when connecting built-in devices to which pipes cannot be connected.
A special type is the liner for the mixer. Without it, it is impossible to connect a single mixer to the system if old steel communications are preserved in the apartment or house.
When purchasing a flexible eyeliner, you need to know exactly what it is intended for and under what conditions it will be used. Before purchasing, you need to check the product for integrity and proper quality of the metal. If you have any doubts about the quality, you should read the documentation.
During installation, certain conditions must be observed:
- the bending radius of the liner should not exceed six diameters;
- if necessary, installation can be facilitated by elbows, gates and;
- during installation, the product must not be pulled or twisted (it may break);
- Installation in places where condensation is possible is not advisable;
- exposure is not allowed high temperature or open fire;
- the end of the attached element must be perfectly flat;
- the nut is first tightened by hand, only then with a wrench;
- During installation, it is important not to damage the seal.
