How to install the bathroom plumbing? What are the precautions for bathroom plumbing installation? These questions are very important for friends who are decorating. After all, only by understanding the relevant knowledge can we know whether the construction personnel are constructing according to the specifications, whether the construction procedures are wrong, and whether the construction quality is guaranteed…
The bathroom plumbing installation method mainly has the following points:
1. There should be an indoor main valve for the water inlet. Before installation, it is necessary to check whether the water pipes and connecting accessories are damaged, sand holes, cracks, etc.
2. When installing kitchen and bathroom pipes, the size of the pipes outside the wall should take into account the final size after the wall tiles are pasted, that is, the thickness of the wall tiles should be considered in advance.
3. In the wall and under the ground, use less or no connecting accessories as much as possible to reduce the hidden danger of leakage. The installation of the connection fittings must be firm and free from leakage.
4. When designing water pipes, the installation position of the faucet of the washing machine and the layout of the water should be considered. At the same time, pay attention to whether the location of the power socket is appropriate. If you put a drum washing machine in the kitchen cabinet, you must determine the size of the washing machine and the kitchen cabinet, so as to reserve the position of the upper and lower water.
During the installation process, there are the following precautions:
1. Generally, bathrooms have separate hot and cold water pipes, mostly made of PPR pipes, and the distance between the hot and cold pipes should not be too close.
2. The bathroom water pipes pass through the roof, which can reduce the chance of man-made damage. The interface and outlet of the cold and heat pipes must be parallel. Generally, the left side is the hot water pipe, and the right side is the cold water pipe.
3. The line design of the pipeline should avoid bending and keep away from the circuit as much 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.
4. Both the cold and hot water pipes are built into the wall. When opening the groove, the depth of the groove must be checked, and the cold and hot water pipes cannot be in the same groove.
5. When installing the water inlet and outlet of the water heater, the water inlet valve and the air inlet valve must be considered and installed in the corresponding positions.
6. When installing the hot water pipe, pay attention to distinguishing the water inlet and outlet of the water heater. The water inlet is connected to the main valve, and the water outlet is connected to the bathroom pipeline. After installation, first open the valve to confirm that there is no water leakage, etc., and finally install the faucet, shower, etc. in the bathroom. The height of the shower pipe is between 1.8M–2.1M.
7. It is the pressure measurement process of toilet water pipe installation: before the pressure test, the valve behind the water meter should be closed, the end of the pressure test pipe should be blocked and water should be injected slowly. It is qualified if the pressure drop within one hour does not exceed 0.05Mpa.
The owner is not a construction worker. Therefore, it is not necessary to understand the installation method of each step, but it is necessary to grasp the general direction to confirm whether the construction of the construction personnel is standardized and whether it affects the quality of the project.
