My bath room smell when out side tempture below 40F, like fall and winter, it is the sewer smell. When the weather is wormer the smell stopped I like to know why and how to solve the problem.

As I have explained, 0dor raises with warm weather and descends when the weather's wet or chilly. So with rainy or cold weather you get more of it.

Sometime a faulty wax seal will stop liquid but allow sewer gas to pass. That's what I'd check first. For smells and noises you almost have to be there. Good luck, Tom
