My family's bathroom is very strange, the original exhaust is because there is a taste, but the opening up, often is the more row of smelly, can not find any reason to buy fresh air things, it seems that no effect, hope we all know Help to see what the reasons, and I was here to decorate less than two years time.
The problem of floor drain
To see if the smell is not from the ground to return out, if it is, for a deodorant floor drain, so that when there is no water, the ground drain is closed, the taste of the sewer does not come, only when the water will be opened, This will solve your problem
Is not your exhaust to have problems.
The first to change the anti-odor of the floor drain the second row of the wind line is not the exhaust is the wind usually did not taste when people are not in the bathroom. I think this may be the case
