Toilet hose: what types of flexible hoses are there, connection features

Not only the comfort when visiting the restroom, but also the safety of its operation depends on the correct installation of plumbing fixtures in the toilet room. Since if the water supply to the toilet is not carried out correctly, this can lead not only to problems with the drainage, but also to problems with the neighbors, who are unlikely to see water dripping from the ceiling.

The instructions below will help you avoid the above problems and perform all the work correctly.

Types of supply

There are several options for eyeliner, between which there are significant differences. The choice of hose will largely depend on the type of water supply provided by the design of the already installed plumbing.

Lateral approach is the most common. The hole is located in the side of the cistern. This arrangement is convenient for installation and repair work. True, in some cases the desired side of the tank may be located close to the wall, sink or other interior items.

In such situations, flexible hoses come to the rescue, which will be discussed in more detail below.

The rear liner has its own characteristics that must be taken into account during the installation process. It is not very popular, since toilets are usually installed close to the wall, and here some distance is required. Maintaining such a system will be problematic.

Bottom line is the most attractive system, since all pipes are hidden from the eyes of users. But it is quite difficult in terms of installation and sealing

Flexible gas connection

The flexible gas supply is a flexible metal hose with fittings. When using it, gas appliances are connected to receiving stationary gas installations for individual use in order to supply natural or liquefied gas to gas appliances. The flexible bellows gas connection is very reliable in operation. In addition, it is easy to bend with your hands, which makes installation simple and convenient.

Flexible mounting parts are recommended for use in cases where it is impossible to connect a gas pipe to the device using metal pipes.

From us you can purchase gas supply both retail and wholesale. Wholesale purchases allow you to receive additional discounts on the purchased goods.

Types of hoses

The stores offer a wide variety of water hoses for connecting to the toilet. However, this entire range is divided into two large groups.

Hard eyeliners

They remain in demand, although other options have already existed on the market for a long time. They are mainly used in old houses. Such elements are made of metal: steel, brass, copper, bronze.

This type of water supply is characterized by high reliability and long service life (ranging from 15 to 20 years depending on the material and conditions). The best characteristics are provided by stainless steel liners, which are highly resistant to corrosion.

A rigid connection is difficult to install. This process takes a lot of time and effort and requires the use of professional tools. It will be difficult for a person without experience to cope with this work.

Flexible hoses

They are highly popular due to their elasticity, which is combined with reliability and relative durability. This type of supply is characterized by a number of positive features:

simple and quick installation;
low probability of leaks;
high reliability;
affordable price;
attractive appearance and compactness.

The flexible supply, in turn, is divided into bellows and reinforced varieties.

Bellows hoses are mostly made of stainless steel and come in different diameters and lengths. Their features are:

ability to take different shapes;
stretch to the desired length;
withstand large temperature changes and water hammer.

High-quality eyeliners of this type can be used for up to 25 years.

Reinforced flexible hoses are made from rubber and stainless steel. There is also high resistance to temperature changes, although the range is not as wide as in the case of bellows analogues.
Therefore, they are not used for installing heating systems, but they are excellent for connecting toilets. The design consists of a rubber hose, on top of which there is a reinforced stainless steel casing (sheath). The cost of such a supply is lower than that of bellows, but the service life is not as long.

Operation and Maintenance

The line must be operated without exceeding the parameters (nominal pressure and temperature of the working medium) set out in the “Technical Specifications” table.
During operation, exposure of the liner to mineral oils, solvents, liquid hydrocarbons and other liquids that are aggressive to the liner materials is not allowed.
It is prohibited to operate the liner at sub-zero temperatures and in close proximity to objects with a surface temperature of more than 200ºС and open fire.
During operation, the liner should be protected from mechanical damage.
The quality of tightening of the liner connections should be checked at least once every 6 months.
When reinstalling the flexible hose, check the integrity of the rubber gaskets. Gaskets should be replaced if they are significantly worn or damaged.

Installation recommendations

Installing modern inlets is not particularly difficult. If you follow the advice of experts, you will be able to achieve a positive result without much difficulty.

Inspection of the purchased eyeliner and assessment of its integrity. If there are even the slightest cracks, you will have to put it aside and go to the store for a new hose. In the future, any defect develops into a serious problem, leading to the fact that after a short time you will have to replace the water supply to the toilet again.
Before installation work, you should shut off the water supply so as not to cause a flood for yourself and your neighbors.
To prevent the formation of corrosion on the elements of the supply system, it is necessary to correctly make all connections . It is important to maintain the consistency of the materials from which different parts are made. For example, copper must be connected to the same copper, brass to brass or copper, which is allowed by the installation rules.
The hoses should not be overly stretched or twisted . This will reduce their service life and the strength of the entire system. It is better to immediately buy a hose with a spare length.
Threaded connecting parts (nuts, fittings) must not be tightened too much. In addition, all joints must be sealed with silicone-based sealant or polymer plumbing tape. The sealant should be allowed to dry for several hours, and only then do a test run of water into the toilet cistern.
According to the rules, the bending radius of the pipe must be 5 times greater than the outer diameter.
Upon completion of installation work, the system must be checked for leaks. To do this, you need to observe its functioning for some time. If even the slightest leak is detected, the connection points will need to be tightened more tightly.

Twice a year, the water supply to the toilet is inspected for leaks. The hose must be replaced every 6-7 years (despite manufacturers’ requests for a longer service life).

General information

Toilet installation steps

Installation work in the bathroom has its own nuances and involves certain sequential actions:
1. Selecting a toilet model. There is a wide range of products on the market; you need to choose one that is convenient for a specific room, durable, and easy to install.
2.Preparation of tools and materials. It is necessary to determine the method of fixing the product, whether a cement solution or epoxy glue will be needed. Modern models are fastened using anchor bolts or dowels. Therefore, it is necessary to prepare those elements that are suitable for this type of toilet. You will also need flexible hoses for water supply, sealant, etc.
3.The immediate process of installing the toilet. Different methods are suitable for this; it is important to install the toilet level and firmly so that its use is safe.
4.Connecting plumbing to the drainage and sewer system.
5. Testing the device for the quality of the work performed, so that there are no leaks, failures of the drain and filling systems.

Water supply to plumbing fixtures

You can do the supply work to the toilet yourself. There are features of the work at each stage. They must be taken into account in order to quickly and correctly install the system.

Before starting work, completely turn off the water supply system to prevent leaks and flooding.

Next, the type of connection to the drain tank is determined. The hard type of liner, formed from special steel pipes, is widespread. The often used flexible hose method is created from highly flexible hoses. They have increased wear resistance, strength, and do not lose their properties during installation and further use.

Attention! Rigid liners can be found in old houses; in modern apartments the flexible type is more often used.

For the toilet liner, a rubber method is used; the surface of the liner is formed from special metal threads. Connecting the toilet to the water supply in this way guarantees the operation of the plumbing for many years, but only water from the cold drainage system should flow through the rubber liner.

A fairly common method of installation is metal, using a corrugated pipe. The corrugated pipe is created from heavy-duty material; all structural elements are made of stainless steel, which does not lend itself to corrosion. In this way, you can easily and efficiently supply water to your plumbing fixtures.

Attention! The choice of supply elements depends on the specifics of the installation work, the cost of the product and the availability of certain functions. Flexible eyeliner costs from sixty to three thousand rubles.

Different ways of eyeliner

Each toilet model has design features, and therefore differs in the way it is connected to the tank, which are equipped, depending on the type, with different elements in individual places. The tank can be attached to the base of the toilet, or be hinged, or hidden, in which case it must be attached to the wall, or hidden behind a false wall. It is possible to install any type of toilet liner yourself, the main thing is to decide in advance on the appropriate type of liner.

How to choose the right eyeliner. Before going to the store, determine the type of water supply to the toilet yourself.

First, measure the cross-section of the hose, the distance between the pipeline and the toilet. Determine the type of water supply to the tank, in which part of the tank the hole for the tube is located, take into account the internal or external thread, and the indicator of water pressure in the pipes. In order not to resort to installing adapters, you must remember to match the threads of the plumbing fixtures with the threads on the fittings. It is better to take eyeliner from plastic or silumin.

Important! A high-quality eyeliner cannot weigh little.

If you have collected enough information about the product and the features of installation work, then the correct choice of eyeliner is easy to make.

How to choose the right product

Flexible product

The criteria for choosing an eyeliner need to be determined before purchasing it. Necessary:

measure the distance from the pipe to the plumbing, as well as the diameter of the hose;
find out the connection method, which depends on the design of the tank;
take into account the type of thread (external, internal);
take into account the water pressure in the pipes;
remember to match the outlet fittings to the threads of the equipment in order to do without adapters;
give preference to such product materials as silumin, plastic;
pay attention to the weight of the eyeliner - light weight indicates low quality.

The more information collected, the easier it is to make a choice.

Types of water supply to the toilet

The drain containers contain holes for supplying water; the holes can be located in different places in the tank, so the following types are distinguished:

The liner is on the side of the tank. The water hole is on the side; this type of toilet is the most common. Installation work on the eyeliner can be carried out easily if there is room for access on the side. If the sink is installed closely, then difficulties may arise. In this case, it is better to choose a flexible hose method, when the hose can be slightly bent.
Eyeliner at the back of the tank. This type of liner is less common because access to the rear hole is not always convenient or possible. In this case, the toilet should be mounted at a distance from the wall to allow access to the pipes in case of emergency.
Eyeliner from the bottom of the tank. This method is the most invisible to others, but has a number of difficulties during installation. First, the tank is connected to the plumbing system, and then secured to the toilet bowl.

Reinforced

The first type of flexible hose is a soft elastic hose, reinforced with wire braid, with connecting elements at the ends (fittings). The tube has a complex structure, despite its simple appearance. It is made from synthetic EPDM rubber or PEX cross-linked polyethylene. It is braided with a thread of wire made of stainless steel or aluminum. The reinforced liner, which can withstand higher pressure, has a nylon braid.

Mr. Build recommends (strongly!): Do not use flexible hose with galvanized wire braid. This is the most unreliable hose that can burst at any moment.

The product is cut at the factory into pieces of the required length. At the ends, metal nipples with fittings or union nuts are inserted into it. Then the braid with the hose is compressed with a steel sleeve around the bushing. Connection to pipes is made through rubber seals.

Flexible water liner has different diameters: 1 and 1/2 inches, 3/4, 3/8.

Features of installation work on water supply to plumbing fixtures

Installation of the water supply system occurs in the following order:
1. First, you need to turn off the power to the plumbing fixture so as not to flood.
2. One side of the line, consisting of a flexible hose or rigid pipe, is connected to the riser of the pipeline system; a regular fitting will cope with this task.
3. The opposite part of the liner is inserted into the tank; for this purpose, there is a small hole in the drain tank.
4. The eyeliner is tested for the quality of the work performed using an artificial method. For greater strength of connections between structural parts, all joints must be treated with silicone sealant and provided with gaskets.
5.Next, the operation of the system is checked in natural mode; to check, the water is washed off two to three times; during operation of the drain and fill system, the presence of leaks and malfunctions is carefully monitored. If no problems arise, then you can use the toilet.

The work on connecting the toilet is simple and understandable even for a beginner; it does not require special knowledge and the use of special equipment, as well as large physical costs.

Circuit examples

The pipe layout in each apartment, even in a standard house, is individual - plumbing and household appliances are arranged differently, and naturally the layout will be different. In reality, everything is not so complicated, you just need to decide on the basic parameters of the circuit - where to supply the water and the type of wiring - will you pull in parallel or in series. Then everything is dictated by the position of consumers. To make it a little easier, let's add a few more diagrams and photos.

The peculiarity of this scheme is that a thicker pipe from the hot water supply goes to the heated towel rail.
This was done to ensure better heating. An example of sequential wiring - equipment at the entrance to the apartment to increase security

If the sewer pipe is on the side of the toilet

Sometimes situations arise when connecting a toilet with a direct or oblique outlet is technically impossible to do under its tank, and the sewer outlet is located on the side. The problem is not insoluble; the problem is solved by using 90-degree corner bends. You can use standard products for installing internal sewerage in the form of short pipes; a more practical option is to use a drain pipe designed to lead the riser outside (the roof).

The toilet drain pipe has a cuff at one end in the form of a membrane, which is placed over the bowl outlet, and the second end of the pipe is inserted into the sewer pipe; if the length is not enough, additional pipe sections are used.

Connecting and installing a toilet is easy to do with your own hands, saving significant financial resources; to carry out the work you will need ordinary household tools and a construction hammer. A more complex and labor-intensive procedure, which takes a lot of time, is if suspended modifications are mounted and connected with installation. However, thanks to numerous videos on the Internet, you can always learn how to properly connect a toilet - in the end, any owner without special plumbing skills can easily handle the job.

Selecting a location

The layout of the toilet room should begin with the choice of toilet. It is necessary to take into account all its features. Only after this should you proceed with further actions. Of course, if there is an old toilet, it must be dismantled. Most likely, the room will still have to undergo major renovations. And it includes updating the sewer lines, floor screed, and cladding.

Before installation, you need to evaluate the dimensions of the new plumbing fixture. This will allow you to understand how best to place it: in the center of the room or closer to the wall. It might be better to mount it on the wall or move it close to the bathroom. It is necessary to decide on the height at which it is better to install the toilet. Today, modern models are able to satisfy any whim in this regard.

The unconventional location of the sewer pipe can be a difficult task. Therefore, it is worth considering the best options in advance. Perhaps it is worth expanding the pipe itself or extending it, or maybe it would be better to choose a non-standard model of plumbing fixtures. Of course, it is ideal if the toilet can be connected vertically at an angle of 90 degrees. It is worth remembering that it is better if there are as few intermediate parts between the toilet and the sewer as possible.

You can draw a diagram of the location of the toilet and other items in the toilet. This will make it more clear whether angular placement of the structure is necessary or whether the generally accepted standard can be used. In modern new buildings everything is simple. After all, here the toilet is installed from scratch, all communications are connected taking into account a variety of models. In the old Khrushchev buildings everything is clearly more complicated.
