The bathroom should be changed to water supply and drainage pipes, how to change it

1. Preparation before installation:

The water inlet should be equipped with an indoor main valve, and the water pipes and connecting accessories must be checked for damage, sand holes, cracks and other phenomena before installation.

When installing kitchen and bathroom pipes, the size of the pipes on the wall should take into account the final size of the wall tiles after they are pasted, that is, the thickness of the wall tiles should be considered in advance.

In the wall and under the ground, use as little or no connection accessories as possible to reduce the potential leakage points. The installation of connecting accessories should be firm and free of leakage.

When designing the water pipe, you should consider the location of the faucet installation of the washing machine and the arrangement of the sewer. At the same time, pay attention to whether the location of the power outlet is appropriate. When placing a drum washing machine in the kitchen cabinet, be sure to determine the size of the washing machine and kitchen cabinet, so as to leave a good position for loading and unloading water.

2. Installation process and precautions:

Generally, the bathroom has hot and cold water pipes, and the material is mostly PPR pipes, and the spacing between the hot and cold pipes should not be too close.

Bathroom pipes run through the roof, which reduces the chance of man-made damage. The interfaces and outlets of the hot and cold pipes must be parallel. Generally, the left side is hot and the right side is a cold water pipe.

The wiring of the pipe should be designed in such a way as to avoid bending and as far away from the circuit as possible. Finally, the position and slope of the pipe clamp should also meet the requirements, and each valve should be installed flat to facilitate future use and maintenance.

The cold and hot water pipes are all into the wall, and the depth of the tank needs to be checked when slotting, and the cold and hot water pipes cannot be the same tank.

When installing the water heater inlet and outlet, the water inlet valve and the air inlet valve must be considered and installed in the corresponding position.

When installing hot water pipes, it is necessary to pay attention to distinguishing between the water inlet and the outlet of the water heater, the water inlet is connected to the main valve, and the water outlet is connected to the toilet pipe. After installation, first open the valve to make sure that there is no water leakage, and finally install faucets, showers, etc. in the bathroom. The height of the shower water pipe is between.

It is the pressure measurement process of the installation of the toilet water pipe: the valve behind the water meter should be closed before the pressure test, the tail end of the pressure test pipe should be blocked and slowly filled with water, and the sealing inspection should be carried out after being filled with water, and then the pressure should be manually boosted, and the pressure drop within half an hour should not exceed the qualified.

Get a professional to consult. Depending on the situation on the spot, it is necessary to consider whether it is anti-water or not. Generally, the sewer pipes of the low-rise are quite deep, and a little groove in the ground will not break, if it is a high-rise, the sewer pipes are one layer below your house, and they will not break.
