The drain valve is used to ensure that the water supply system and other water appliances in homes work without problems and malfunctions. Thanks to this element, it is possible to free pipes from water, which is especially important in houses for seasonal stay (in summer cottages).
In severe frosts, low temperatures, climatic surges, the pipes will not burst. Specialists install a drain valve at certain points in the water system during the installation of pipes. There are options for mounting systems that provide for the presence of cranes, they are already built into the pipes. This facilitates the installation process and also simplifies the operation of the instruments.
Secrets of installation
Plastic or metal materials can be used in the process of creating a water pipe. The first option is easy to install and reliable, because the material bends well, so you can lay pipes in hard-to-reach and narrow places, without worrying about expanding the working area. But at low temperatures, plastic bursts and deforms faster than metal counterparts.
As for the metal, the pipes are made ofit is much more durable and reliable, but their cost is higher. Cranes are often placed on a metal base and securely welded to the surface. This allows you to save time on mounting additional elements and quickly assemble the structure to complete the job.
Main elements
The basic installation rules include the placement of pipeline elements at the desired level. Pipeline elements must be mounted with a slope to a well or other source, this ensures easy water runoff during conservation.
Also, the drain valve does not burst when the load on the system increases. On the pipe through which water is supplied to the house, it is necessary to install a special valve. He stops the liquid so that it does not go by gravity into the well. As for the installation of taps, they must be higher than the valve.
The drain valve is cut into the base of the pipe using different seam processing methods. For standard pipes of the water type, ordinary automatic taps are used, which can be assembled according to the drawings from the instructions. Also, the automatic version is used for drawing water from a well or for continuous supply from a well using a vibration pump. Thanks to the automation of the system, liquid residues remain on the supply hose. When the machine is turned on, the pressure increases, and the liquid is again supplied to the house. A prerequisite for both automatic and conventional faucets is the presence of a drain valve.
Preservationpipes
For this process, you need to open all the drains, even on the washbasin faucets, so that the liquid completely exits the pipeline. Residual water in winter can freeze and expand in the pipes, causing damage and bursting if you do not use the room. The complete cleaning process uses a compressor to blow through the entire system, which inflates car tires.
It quickly blows the rest of the water out of the pipes, leaving all the drains clean. To blow excess water out of the drain valve, more power must be added to the compressor.
During the conservation process, care must be taken to ensure that the pipe and valve are completely free of water, be sure to blow through all possible areas for this. If for some reason there is no access to all pipes, then conservation can be carried out by blocking the elements with the help of taps on them. The procedure is carried out quickly, does not take much time.
Preparing for winter
Water from the boiler must be drained during the process. To do this manipulation without problems, during the installation of water heating systems, a special tee is made between the cold water pipe and the safety valve, which is equipped with a drain valve with a fitting.
In the process of draining, a drain hose is put on it. Thanks to this, the process of freeing the boiler from water becomes much easier. A prerequisite for the drain process is to disconnect the hot water supply pipe from the appliance.
After emptying the boiler tank fromremaining liquid, be sure to shake it from side to side so that the remaining water comes off the walls. If this is not possible, you should leave the tap open for some more time and wait.
Turning off the washing machine
The ball drain valve is used in these devices for continuous water supply. In the process of disconnecting the hose from the device, the valve must be closed. In the process of turning off the machine, do not forget about the importance of disconnecting the plug from the mains. Doing this while enabled is not recommended. Be sure to unscrew the cover of the drain pump, you need to substitute a container under it, since there may be water in the hose.
To prevent freezing of the pipes of the washing machine in winter, you need to turn it upside down and leave it in this position until spring.
Errors in the process
When installing brass ball valves with a bleed device, craftsmen may lose sight of the fact that there is an additional valve that prevents the liquid from returning to the source. Therefore, before starting the mount, you must definitely look at the work plan and select the right place.
The instructions indicate where it is best to install the cranes. Masters advise doing this in places that are accessible and easy to get close to. This also applies to faucets. It is considered a mistake to install a faucet below the level of the valve or far from the device itself.
