Whether or not to replace the water pipe after smashing the wall needs to be judged according to the actual situation in your home. All the older houses can be replaced. If it is a new house, it is not necessary. If the wall smashing the wall affects the water pipe line, it should be replaced appropriately, do a pressure test and be close to the original line as much as possible.
Generally speaking, not all water pipes need to be replaced after smashing the wall. They should be reasonably arranged according to the actual situation of their own home, rather than blindly replacing the water pipes, otherwise it will have a great impact on the layout of their own home.
If the house is a second-hand house with a long age, the water pipe can be replaced after the decoration hits the wall, which can also prevent the water pipe from aging and inconvenient to use. However, if it is a new house, it is completely unnecessary to replace the water pipe after smashing the wall. At this time, the water pipes are basically intact and very wasteful.
If the wall is close to the water pipe or the water pipe line, it is undoubtedly to be replaced, but in the process of replacement, if the original line can be used, the original line shall be used, and the pressure test of the water pipe shall be done at the same time, so as to avoid water leakage after replacing the water pipe.
