Answer: What you mean by "backwater" should refer to the backwater bend (water trap) set up in the toilet sewer, which is to use the water storage to block the reptile in the sewer. Because this kind of backwater bend is easy to cause sewer blockage, it is not easy to dredge after blockage, etc., and it is basically not commonly used now. >>>More

Several sewer pipe diameters are commonly used. The outer diameter of the outlet is 32mm, the inner diameter of the inlet pipe is 32mm, the outlet sealing cover is 60mm, and the expansion and contraction of the pipe is about 40cm to 110cm. According to different toilets, when choosing the diameter of the sewer pipe, it is also necessary to consider whether the sewer pipe drainage, the water inlet and the drain pipe of the toilet are consistent, if the nominal outer diameter of the drain pipe of the toilet is 110mm, then the diameter of the connected sewer pipe should also be 110mm.
