What do you need to pay attention to during the construction and repair of cement drainage pipes? In the decoration of family homes, leakage of water supply and cement anticorrosive drainage pipes often occurs. The only way is to strictly follow the process requirements to ensure the quality of the project. For everyone:
The cement anti-corrosion drainage pipe shall be threaded and the exposed joint shall have exposed threads. The end of the device shall be fixed with a pipe clamp in a timely manner. The connection between the pipe and the fitting or valve shall be strong without any looseness. Use visual inspection and feel to see if there is leakage. Check whether all faucets and valves are flat, whether they are sensitive to open, whether the water is cleared, and whether there is leakage. Check whether the water meter is operating normally. The pipeline can be closed for the next operation.
Regarding some special situations, you should take special care to avoid future problems. For example, the pipe is very long, connecting the kitchen and bathroom, or leading to the balcony, the pipe must pass through the living room or room. Because the pipe is either buried in the wall or laid under the floor Once the problem occurs, the result will be very serious, so there should be no joints in the center. Also, the diameter of the pipe should be appropriately enlarged to avoid blockage. If the pipe is long and there are many elbows, an inspection port must be set in an appropriate position to facilitate future pipe repairs. For hot water pipelines, galvanized iron pipes must not be used to avoid water pipe rust and scale formation.
