A, cold and hot water pipe into the wall standard
1. Keep the distance: If the distance between the hot and cold water pipes is too close, the cold water pipe will interfere with the thermal insulation function of the hot water pipe. Even if the water in the cold water pipe is heated to a certain extent, it will still absorb the heat of the hot water pipe. According to the construction specification, the distance between hot and cold water pipes should be kept at 20 cm, so that the hot and cold water pipes will not interfere with each other.
2, hot and cold water pipes need to be fixed: the construction process comes and goes, and it is inevitable to bump. In this case, the water pipe is easy to be kicked, which makes the water pipe loose and causes water leakage. The fixing ring can be used to fix the water pipe, which can reduce the displacement of the water pipe when it bumps, protect the water pipe and reduce the probability of water leakage.
3. Coverage thickness: when the water pipe enters the wall, the cement mortar thickness of the cold water pipe is 15 mm, and the cement mortar thickness of the hot water pipe is15 mm; When the water pipe enters the ground, the mortar thickness should not be less than 10 mm.
4. When the water pressure is not enough, the stem should be thick and the branch should be thin: if the pipe diameter is too long, the water pressure at the end of the pipe will be low, and the water flow will be correspondingly small. The solution is to branch pipes at the door of water heater, kitchen and bathroom, and then maintain the stability of water pressure with four pipes with 20mm main pipes.
Second, can hot and cold water pipes be in the same water tank?
Do not select the same slot. Putting hot and cold water pipes together has a great disadvantage, that is, hot water becomes warm water and is not insulated. The original outlet water temperature was 80 degrees, and it turned into 60 degrees after walking around. The temperature is losing too fast, so the hot water can't be used normally. This is a big problem. When we decorate hot and cold water pipes, we should make a good plan. Hot and cold water pipes should be separated, the distance should not be too close, the pipes should not be too bent, and the valve position should be neat. This is for future maintenance. It's a mess. If you want to repair it, you have to find the location of the pipeline for half a day.
All the above are about the standards for hot and cold water pipes entering the wall. Can hot and cold water pipes be in the same water tank? I hope it can help you understand the installation of hot and cold water pipes. Please continue to pay attention to more decoration knowledge, decoration company evaluation and decoration cases!
