Anonymous users2024-01-23On rainy days, humidity and air pressure increase, resulting in poor ventilation and exhaust, and a large amount of odor will overflow. Factors:
The traditional floor drain only realizes the drainage function, but does not realize the sealing function, and the water seal and backwater bend cannot prevent the aftertaste.
The floor drains selected for the self-decorated bathrooms are all unqualified floor drains that do not even have water seals, which cannot prevent the smell from returning at all.
Most of the newly built buildings have even canceled the backwater bend, and the aftertaste is even worse.
Both left and right. Since there is no trap, it is easy for odors to overflow directly. A trap should be set up like the two sewer pipes in the middle to prevent the odor from overflowing to a certain extent.
The outside sewer pipe is not good, and when it rains, water enters the sewer well, occupying the flow and making the toilet drain poor.
It is very likely that the exterior wall is leaking or the bathroom exhaust well seeps water from the top, more information, better advice, free concrete waterproofing and leakage repair technical advice, to avoid today's repair, tomorrow's leakage, annual repair, annual leakage trouble.
