1. The anti water hole at the bottom of the toilet bowl should not be sealed during installation

The water storage hole at the bottom of the toilet was smashed into a small hole, which can be used, first of all, go to Pinduoduo to buy a small bucket of plugging glue, and then use a small shovel to wipe the plugging glue on the small hole of the smashed building, which can be used, because the plugging glue is the kind that is not afraid of water, and it can also be plugged in the water. Saving good morality.

It's the water in your own house, if it's not that the downstairs sewers are all blocked.

Choose which drain to use, seal the other drain with a plugging material, put a sealing ring on the drain, glue the ground, fix the direction and make a circle of glue around the toilet.

It is impossible for this small outlet hole to return to the smell, check whether the floor drain cover next to it is covered, and it will return to the smell.

It's the toilet that is broken, usually the self-closing device is not reset. Please press the flush button a few more times to give it a try, and it may be restored. If it cannot be restored, the toilet angle valve can be closed before it is repaired to prevent wasting water.
