[0002] The building water supply system is a cold water supply system that introduces the water from the urban water supply network or the self-provided water source water supply network into the room, sends it to the domestic, production and fire fighting water use equipment through the distribution pipe, and meets the water volume, water pressure and water quality requirements of each water use point. The building water supply and drainage system actually includes two aspects: the building water supply system and the building drainage system.

[0003] In the existing patent with the application number CN 202010876740.7, a building water supply and drainage sewage pipeline is disclosed. An electric push rod extrusion plate moves back and forth in a water storage box, so that a spray elbow sprays water towards the bottom of the drainage pipe, and is combined with a stirring plate to stir, so that sundries are not easily deposited at the bottom of the corner of the drainage pipe. However, the sundries after cleaning still remain in the pipeline. After the water supply and drainage pipeline is used for a long time, sundries are easy to accumulate at the elbow pipe, and the stirring plate and the spray elbow cannot effectively clean the impurities, affecting the drainage use.
