Can the three holes of the toilet be plugged if they emit odors?

These two barrels should be useless, and they can be plugged if the smell is emitted from these two holes. If there is a peculiar smell coming out of these two buckets, it means that it is connected to the toilet sewer pipe, and it is likely to be used to clean the toilet.

The hole in China is used to insert that white hose to fill the toilet bowl with water.

The toilet has a peculiar smell, it may be that the water cover is too low, the landlord can put the pipe into the hole in the middle, so that after each charge, the pipe will continue to inject some water into the toilet through this hole when the water is on, in case there is a peculiar smell.

The two holes on both sides should be related to the lid removed by the landlord above, to fix the lid, and generally will not communicate with the bottom of the toilet.

So, the three holes can be sealed, and it doesn't have a big impact. However, the odor is most likely not the cause of the toilet. It is likely that the floor drain is not tightly sealed. The landlord should check the floor drain.

Don't block, eat less garlic, flush quickly, squat less in the toilet, mix warm water with disinfectant, brush the bucket and pipes, and brush the holes, and soak the toilet for about half an hour.

The two holes in my house are not at the top end, on both sides of the bottom end, I glued them with tape, and they really smell!

It can be blocked, but it doesn't work with the sewer.

Probably not!

If it does smell bad, you can find something to plug it up.
