Take the underground pipe (dark water) for example, that is, the water pipe is hidden in the wall or underground, and the pipe is not exposed, so we can't directly see the direction and layout of the pipe. This depends on the use of space. If it is a rented house, a simple office space, or a commercial space that pursues industrial style, it can be an open pipe, and even the industrial-style commercial space pipeline can use old-fashioned iron pipes or stainless steel pipes. After all, the more industrial, the bathroom can be said to be the place with the most home improvement pipes. In order to improve the beauty of the bathroom, most consumers will consider the bathroom as a pre-buried water pipe to avoid the trouble caused by dense pipes. But in this case, once waterproof, no water pipe has a longer service life. Generally, PPR pipes are used in home decoration water pipes, which cannot be installed openly.
Secondly, many water pipes will leak after a period of use. Besides pipe quality and construction technology, water hammer phenomenon is the culprit. The bathroom with concealed water pipes is beautiful, inconvenient for later maintenance, and the reconstruction cost of water seepage or leakage is high. People choose the underground water construction method, although it affects the application of new materials in the building materials market. People choose to lie underground. The biggest disadvantage of Ming Guan is that it affects aesthetics, practicality and efficiency. The water pipe leaks and is easy to maintain.
