First, why are there two holes in the bottom of the toilet?

There are two holes in the bottom of the toilet, one is the blowdown hole and the other is the reserved sewage outlet. The main function of these two holes is to connect water pipes. In order to adapt to different pit spacing, you can choose the appropriate drainage hole according to the pit spacing reserved in your bathroom during installation. If the reserved sewage outlet is 30cm away from the corner, choose the hole of 30cm, which is the hole behind the toilet. If it is 40cm, it is recommended to choose the hole in front. After selection, another hole was sealed with special mud. Special attention should be paid when sealing, if the sealing effect is not good, it is likely to lead to water leakage at the bottom of the toilet when flushing.

Second, what are the reasons for the stench of the two holes behind the toilet?

1, not closed.

There are two small holes in the back of the toilet, which need to be sealed with silicone sealants. Because it is connected to the drainage place, if the seal is not good, it is likely to lead to odor reflux.

2. Failure of sealing ring

If the sealing ring of toilet flange is aged or improperly installed, it will cause the problem of toilet odor. In this case, it is recommended to completely close the two holes behind the toilet with glue, or reinstall the toilet and seal the sealing ring.

Pay special attention when reinstalling the toilet. If the toilet seat is not clean enough or uneven, it is recommended to carve the rubber tea of the sealing ring, and then put it on the first sealing ring before installing the toilet. After sticking it with sealant, there will be no odor.
