How to solve the problem of toilet drain smell

There are three reasons why bathroom drains stink:

1. The sealing of the toilet sewer pipe is not tight, and there is a gap between the sealing gasket of the toilet sewer connector and the cast iron or UPVC pipe.

Solution: Open the toilet bowl to see, or look down and smell, if this is the reason, seal it with putty or fireproof mud, install the toilet, and glue around the toilet and the ground to seal it for a second time.

2. There is no water seal on the floor drain, and the odor can not be effectively sewn and stopped.

Solution: If this is the reason, go to the market and buy an odor-proof floor drain.

3. The S bend of the basin drain is not sealed, and the bending is not enough, and the water cannot be stored, resulting in the smell of return.

Solution: If this is the case, seal the S-bend and adjust the curvature.

4. Check whether the bathroom exhaust fan has a check valve, and whether there is an air duct odor channeling phenomenon.

The above points, focusing on the toilet bowl, the general situation is that the sewage well is separated from the reclaimed well, and under normal circumstances, 2 3 items will not appear.

Brush frequently, and then you can put cut fresh lemon in the bathroom, or the kind of essential oil that costs a few cents a piece.
