Anonymous users2024-01-24GB50242 clearly stipulates that the slope of the domestic sewage plastic pipe must meet the design requirements or the provisions of this code (the standard slope of De110 is %, and the minimum slope is %. Inverted slopes are absolutely not allowed.
People who don't even understand the specifications can still say that it doesn't affect the use, and they really don't even understand that hole to eat and that hole to pull out. These are all people who deceive and coax, they get the money, they turn their backs and don't recognize people, you let him go today, tomorrow he will ignore you. You must ask them to repair, otherwise you will have to suffer in the future, and you will pay someone to dredge it in three days, and it will affect the residents downstairs.
GB50242-2002 is the "Code for the Acceptance of Construction Quality of Building Water Supply and Drainage and Heating Engineering" formulated by the state, which is not allowed to be violated casually, not to mention that this code also uses the word "must".

88 years of living in the house, I think your bathroom sewer pipe is a cast iron pipe, if it is normal use for about 30 years, this depends on the water quality, if the water quality is alkaline or acidic too high, the chance of bad will be faster. At the same time, it is useless to paint, if there is a small leakage such as sand hole, use the point to plug the leakage, and then use AB glue to coat a layer after drying and it can last for about three years.
Slope of drainage cast iron pipe, slope of drainage PVC pipe. >>>More
A 60-centimeter drop of 6 meters long pipes also requires a 2.5 pipe at the thinnest, and there can be no joints in the middle, so that it will not be blocked.
