Because the domestic sewage drainage system and floor drain anti-odor design of the new building are unreasonable, the toxic gas and odor in the outdoor and sewage pipes are discharged indoors. The kitchen and toilet drainage pipes of the new buildings now reduce the "U" shaped backwater bend, although the construction cost is reduced and the indoor space is increased, but it also opens up the barrier between the sewage pipe and each household. At present, most of the floor drains commonly used by people are traditional bell floor drains. >>>More
