What should I do if the toilet at home keeps smelling?

I don't know if the flavor you add is normal or has a peculiar smell, and everyone's judgment criteria are different. Let me tell you this, if the toilet is installed and qualified, and the quality is fine, there is no peculiar smell gushing out of the pipe, because the base is sealed if the glass glue is tightly beaten, and the toilet will sink a part of the water after each use to prevent the gas in the pipe from gushing. If the situation is the same as your home, the air pressure of the drain pipe is too large and the sink bend cannot stop the gas from rising up, so it is recommended that you ventilate the toilet more, or buy some toilet deodorant on a treasure to use together.

Changing the toilet is to reinstall the anti-odor pad, which will be a little troublesome, but if there is a plumbing reason, it may not be a big user to reinstall it. You can choose to use soda + vinegar + boiling water to sterilize the toilet bowl and remove the odor, or you can dilute the toilet water and pour it into the toilet storage tank to remove the odor.
