Where do you need to design a drain connection?

1. Reduce the bend of the pipeline and help the sewage to be discharged smoothly.

If the indoor sink or shower is connected to the outdoor rainwater system, and the thickness of the pipe is different, it is necessary to carry out stable welding at the joints to avoid water seepage. As far as possible, the corners are not conducive to the circulation of sewage.

2. Dredge the pipeline to ensure smooth drainage.

Rainstorms can happen at any time, and the rain is heavy and urgent. If the drainage system is not smooth, it is prone to blockage, and rainwater cannot drain properly down the pipes. At the same time, it is also related to whether the water outlet is smooth, and when the rainy season comes, it is best to clean the water outlet on the roof of the building, pick up leaves, sweep away the silt, and dredge the pipes to ensure smooth drainage and the safety of the roof.

3. Increase the slope to avoid sewage backflow.

People go to high places, water flows to low places, in the layout, the pipe and the ground should have a certain slope, so that the sewage can flow away as soon as possible, if you encounter heavy rain weather, avoid the rainwater flowing down the pipe to your own backflow situation. In places where there is a lot of rainy season, the slope can be increased accordingly.

Building water supply and drainage construction drawings, first of all, should draw the bottom water supply and drainage layout drawing, followed by the floor layout of each floor, so that the viewer is clear about the direction, direction, the location of each water supply and drainage source and water receiving equipment, as well as the diameter of the pipe section, etc., followed by the system diagram (axis side diagram) of each riser, so that the viewer knows the ins and outs of each system pipeline.

Water supply and drainage need to be coordinated with buildings, structures, HVAC, and electrical. Generally, when other majors are required to cooperate, the funds will be raised, and there is no strict order. For example, the building structure should be funded at the earliest, the location of the sump, and the electricity of the submersible sewage pump should also be funded for the electrical.
