The bathroom is very smelly, whether the water trap leaks the problem

It is unlikely that the toilet will vent its own odor because it is closed with water. It should be that there is a problem with the sealing ring of the two. Or the floor drain is not well sealed (did you buy an odor-proof floor drain?) You can cover the drain tightly with a damp towel first, and then pump a little more to see if it is a problem with the toilet. If not, it can be determined that the floor drain is the problem (replaced odor-proof floor drain and seal). Also, do your exhaust fans have a common duct or do they drain directly to the outside?

Reasons why the bathroom smells, how to find it and suggestions for deodorization.

Odor source. 1. Backproductive exhaust fans.

Odor check method: Go to the roof of the building and take a small piece of paper to the exhaust main pipe to feel if there is air circulation.

Turn off the exhaust fan and check that the exhaust vent is not too large or blocked, causing air to flow back.

Suggestions for deodorization: change the exhaust fan with better sealing, or directly close the opening of the exhaust main pipe to the toilet and open an independent vent.

Odor source. Second, the toilet with poor sealing.

How to check the odor: Check whether there is any water leaking out of the base when the toilet is flushed.

Suggestions for deodorization: Change the toilet bowl or find a way to plug the leak.

Odor source. 3. Lack of water and rotten floor drains.

Odor check method: Knock on the lid of the floor drain to see if it is rotten or lack of water; Or run to the downstairs bathroom (if the downstairs residents have not done the ceiling decoration) to see if there is a water trap in your floor drain.

Deodorization suggestions: Don't be afraid of trouble, change to an anti-odor floor drain with water sealing function; If you are afraid of trouble, find a leather tiger with a toilet to cover the floor drain, and pour some water on the side at the same time, or pour half a cup of water into the floor drain every other day, which can also play a role in water sealing.

Odor source. 4. Forgotten traps and pipes.

Odor check method: check whether there are water traps under the washbasin, toilet, and floor drain (similar to an S-shaped pipe lying flat); Secondly, after the smell of the bathroom is discharged, plug the washbasin with a rubber plug to see if the smell is still there.

Suggestions for deodorization: Go to the building materials market to buy a suitable water trap and ask the decorator to install it.

Knocking down a few floor tiles and rebuilding the pipeline, although the project is huge, the problem is relatively thorough.

Odor source. 5. Overly spacious washing machine outlet pipes.

How to check the odor: Recall or check where the washing machine outlet pipe leads, and check if there is any odor after plugging it.

Deodorization method: Seal the gap between the water outlet hose and the drain outlet of the washing machine with glass glue.

The trap is one of the main accessories of the drainage pipe in the building, and some sanitary appliances have a trap in the structure (such as a seated toilet), and when it is connected to the drainage pipe in the structure, it does not have the ability to block the industrial wastewater receiver and the domestic sewage pipe or other harmful gases that may be generated, and the trap must be set up below the drain.

So your bathroom must be dug up and reinstalled, many developers or designers think that the toilet itself comes with a trap, which can prevent odor, in fact, it is very unprofessional, one is that the interface of the toilet itself and the pipe interface can not be seamlessly connected, and it is exposed, and the toilet will be loosened after a long time, resulting in the smell coming up, and the seal will be weathered over time, and the interface seal is sealed outside, not blocked inside, so no matter what kind of bathroom, what kind of toilet or squatting toilet is used, it is necessary to install a water trap.

This kind of thing has happened to more than a dozen of my customers, I am a professional in dealing with bathroom odors, and I have worked for more than 3 years; 100% of your problems are caused by floor drains; To replace the floor drain, you should buy the kind of stainless steel good, don't pick the plastic one; Go back and seal the floor drain again; There will definitely be no smell;

There is a problem with your trap for one reason, there is also a leak at the bottom of the toilet, and another is a leak in the gap of the floor tile. When you use the exhaust fan, it will only get more and more smelly, and when you open the door, the air will hedge the odor less. You can let a professional master come to your door to repair it.

Basically, the washbasin drain, floor drain and fecal pipe share the same pipe.

Is the bathroom too small, and it is conducive to air exchange after opening the door?
