Water hose: selection and installation instructions: All about pipes
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. How to choose and install a hose, read on.
How to choose a hose
- hose type;
- appointment of an eyeliner;
- eyeliner dimensions;
- hose connections.
Types of flexible water hoses
The main types of hoses used to connect water are:
- reinforced eyeliner. The device is a rubber hose, which is reinforced with metal threads for extra strength. As threads for braiding can be used: stainless steel, nylon, aluminum;
The most durable are eyeliners reinforced with nylon and stainless steel. The devices can be used to supply water with a maximum temperature of 95ºС at a pressure of up to 20 atm.
- bellows connection. Flexible corrugated hose entirely made of stainless steel. Bellows eyeliner is designed for the passage of water with temperatures up to 250ºС. Due to the 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 bellows for 400 - 500 rubles.
Separation of eyeliners according to purpose
According to the purpose, all plumbing connections are divided into devices designed for:
- cold water connections;
- hot water connections.
The hot water hose is distinguished by the presence of a red thread in the sheath, and the cold water inlet is marked with a blue thread.
Most often on sale there is a universal hose for cold and hot water. 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 often enters hot water pipes and vice versa. To avoid problems with connecting plumbing and extend the life of the hose, experts recommend using only 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:
- eyeliner diameter;
- eyeliner length.
The hose diameter is determined based on the throughput. A thin water hose is intended for plumbing that does 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 observed to increase the service life of the product.
Basic criteria for determining hose length
Determining Connection Methods
The water supply hose can be produced with various connection methods. As connecting elements are used:
- a nut designed to be attached to an external thread;
- a thread that connects to an internal thread;
- fitting, mainly used to connect to the 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 connection rules
Before proceeding with the installation of flexible piping, you need to know the basic rules for connecting the device, which are as follows:
- it is not recommended to use eyeliner, the braid of which is broken;
- it is impossible to install a hose, the connecting sleeve of which is not subject to visual inspection;
- the hose must not be stretched during installation. The eyeliner should be installed freely, but without unnecessary kinks;
- if it is necessary to connect the hose from the side, then the kink area must be observed. Twisting the eyeliner along the longitudinal axis is prohibited;
- to reduce kinks, you can use special adapters to reduce the radius;
- if during installation it is necessary to equip a hose bend, then a minimum radius of 70 mm must be observed;
- do not increase the length of the flexible hose by connecting to another supply line.
Do-it-yourself installation
To connect the 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 of the plumbing device;
- remove the unusable eyeliner. For this, a wrench (adjustable) wrench of a certain diameter is used;
- a sealing material is wound on the new eyeliner. Each eyeliner must be equipped with rubber gaskets, but in most cases it is not possible to achieve complete sealing exclusively with the o-rings included in the kit;
- the hose is connected to (toilet);
- the inlet is connected to the outlet of the water pipe.
It is not recommended to tighten the thread with excessive force, as the 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 with a wrench ¼ of a turn.
The method of connecting the eyeliner to the kitchen faucet is shown in the video.
The correct choice of the water hose and compliance with all norms for connecting the device are the key to a long service life of the product. If at least one factor does not meet the established standards, then the eyeliner can go out of service at any time, even with the minimum pressure in the system.
