The norm of hydropower construction is "take the roof instead of the ground, vertical instead of horizontal". Many owners can't accept this specification because they are afraid that the top will affect the appearance. But for the safety of concealed works, it is best to adopt this method.
Because digging the ground may damage the waterproof, and once it leaks, it is difficult to find the leaking place when walking on the ground. This is because water flows downwards, and it doesn't necessarily flow out from the leaking place first. Only when there is water leakage downstairs or "water overflows Jinshan" will water be found, and the loss will be greater.

At the same time, in the process of hydropower transformation, we must pay attention to the material problem:
1, water pipe fittings are not matched.
"Reducing materials" means not only using less materials, but also using inferior materials instead of high-quality materials to earn the difference. In waterway reconstruction, pipeline replacement is less, because owners will pay more attention to it.
However, due to the small size of accessories and the large number of accessories used, it is easy for owners to connect water pipes with inferior accessories if they are not careful and encounter bad decoration companies or construction workers. You know, this approach can easily lead to the failure of the later interface.
2. Cold water pipe mixed with hot water pipe
Due to the influence of thermal expansion and contraction, hot water pipes require higher performance of materials such as high temperature resistance than cold water pipes, and hot water pipes are generally more expensive than cold water pipes. Generally, blue is a cold water pipe and red is a hot water pipe.
All hot water pipes can be used in the construction, and hot and cold water pipes can also be used normally. But some bad construction teams may use cold water pipes as hot water pipes. Although this is no problem for the time being, it is easy to cause cracking and leakage of cold water pipes in the later stage.
