The toilet drain is not very smelly, what should I do to avoid it

Generally, the anti-odor is caused by floor drains, many floor drain water seals are shallow, and the market has to buy a deep water seal floor drain core, which can solve your problems, try.

To remove the smell of the toilet drain, you need to prepare: an appropriate amount of boiling water, dish soap, edible alkali, and a small bowl.

1. First of all, pour the edible alkali into a small bowl as shown in the figure below.

3. Next, pour in boiling water and dissolve the dish soap and edible alkali in a small bowl.

4. Then pour the liquid in the small bowl into the sewer of the bathroom as shown in the figure below.

5. Finally, pour it with boiling water, so that the smell in the toilet drain can be removed.

There are three reasons why the bathroom sewer smells back (I am now a five-star hotel, and I also encounter the same problem,) I categorize as follows:

1. The toilet sewer pipe is not tightly sealed, and there is a gap between the toilet sewer connector sealing gasket and the cast iron or UPVC pipe, disassemble the toilet to see, or look down and smell it, if this is the reason, seal it with putty or fireproof mud, install the toilet, and glue it around the toilet and the ground to close it for secondary sealing.

2. There is no water seal on the floor drain, and the odor can not be effectively sewn and blocked. If this is the reason, go to the market and buy an odor-proof floor drain.

3. The S bend of the basin water is not sealed, and the bending is not enough, and the water can not be stored, resulting in the smell of returning, if this is the reason, the sealing of the S bend can adjust the curvature.

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

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.

The above is detailed enough, this is all typed word by word, and it took half an hour.

Add a p-bend to the sewer pipe to store water to prevent odor.

The bathroom drain stinks when you don't use it.

I guess it's because there is no trap in the sewer.

Upright and easy to smell.

You can only change the sewer to S bend for reference.

There are anti-odor sewer blockages sold in the mall, you can go and check it out, hoping to solve it as soon as possible
