What tests do drain pipes need to do before they are hidden?
The first point is the inspection of appearance and slope. Before the pipeline is concealed, we must carefully check whether the appearance of the pipeline is damaged and whether the joints are connected correctly. Second, we must use a spirit level to measure whether the slope of the pipeline meets the requirements and resolutely put an end to the phenomenon of downhill. The second point is that we are going to do a water test. The so-called water-through experiment is to irrigate the upper mouth of the pipe, and then observe the water flow at the water outlet of the pipe. At this time, we can basically determine whether the buried part of the pipeline is blocked.
Under normal circumstances, the water flow is very smooth. The third point we are going to do is the irrigation test, also called the full water test. During the irrigation test, we should use the corresponding material to block the water outlet of the drainage pipe to ensure that there is no water leakage. Then start the irrigation at the water inlet of the pipeline, the irrigation height is up to the upper edge of the pipeline. At this time, observe whether the water level has fallen, and determine whether there is water leakage in the pipeline.
