What should I do if the bathroom smells?

If there is an odor, there are several situations.

1 As you said, the pvc pipe didn't reach the ground, and dirty water seeped into the cement at the grass-roots level. This has happened, but it is not a problem of floor drain. It's the drainage in the toilet. The water in the floor drain was dirty for several days before it stinks. The smell in the basic bathroom is the smell of ammonia emitted from the toilet. To solve the problem, first take off the toilet, put the toilet into the water and then use the plugging king (high efficiency plugging cement) to deal with it.

2. Deodorization bend in water means that it will deodorize only when there is water. Your new house has never been used. There is no water in the deodorizing elbow, and the smell cannot be sealed. Sure, it stinks. The solution is to use it.

There is something wrong with your floor drain, probably it smells bad. Now it is basically a water-sealed floor drain, which means there is no water in it, so the natural seal is not good. The solution is to use it.

4, the washing machine floor drain, the top cover fell off when cleaning, just change the cover, this you carefully check the floor drain and other equipment, in short, if they are closed tightly, you can avoid this situation.

5. The toilet is blocked, and a lot of dirty things are blocked in the deodorizing elbow of the toilet. After the toilet that is generally not blocked is flushed, the elbow pipe is filled with relatively clean water with little taste. If it is blocked and the elbow is not clean, it will always smell.
