Please help, when the range hood is turned on, the toilet floor drain smells of air

First of all, are you confirming that the floor drain only reverses the air when the range hood is on, so ask because there is no direct relationship between the two, the floor drain goes to the drainage pipe, and the range hood takes the exhaust duct, which may be a coincidence.

It is recommended that you change a floor drain with a water seal, if it is already a floor drain with a water seal, and the house is dry, you can often pour some water into the floor drain to let the water seal its effect, and it is estimated that it will be solved.

These two should not be the same house.

Halo sometimes when using the smoke machine.

The doors and windows are closed very tightly, and it is impermeable, and it forms a vacuum.

A similar situation is also prone to occur.

You try to open the doors and windows.

If it doesn't work, as they say, let's change to an anti-odor floor drain.

Some time ago, I had an aunt who said that the floor drain smelled bad, so she wrapped the floor drain cover in a plastic bag and covered it again.

The taste is gone.

However, the floor drain is wrapped in a plastic bag, if the indoor water leaks, it can not be discharged in time, add a point, or you will change to an odor-proof floor drain, which is sold on the market.

Go to the building materials city to see the new Runshuang automatic sealing floor drain, which should be able to solve it.
