Hello, I have seen your question and am sorting out the answer, please wait for a while 1. The bathroom sewer pipe can pass through the roof, which can reduce man-made damage and facilitate inspection in the future. The hot and cold pipe interface and outlet should be parallel, and the wide range of water pipes should be hot left and cold right. When designing and rectifying, the pipes should be bent as much as possible, so that they can be kept away from the circuit, and each valve should be installed flat for future use and maintenance.

2. When installing the hot water pipe, we should pay attention to distinguishing the water inlet and outlet of the water heater, connect the main valve at the water inlet, but connect the bathroom pipe at the water outlet, and open the valve after the water pipe is installed to ensure that there is no water leakage. 3. The bathroom is a dark and damp place in the whole family, so ventilation is the key, if you can design a window in the bathroom, it is better, if there is no such condition, in order to prevent the bathroom from mold, damp and other problems, then you need to install an exhaust fan, so that the bathroom can also be ventilated.

Please refer to it.
