Sewage odor leaking from bathtub's overflow opening
Posted by Truc Phan on May 03, 2004 at 15:13:15:
I have a bathtub in a 2nd-floor bathroom. Recently, there is a strong sewage odor leaking from the overflow opening. Can anyone help me to pinpoint what's wrong with this? How is a typical overflow connected? Does it have its own P trap or does it share with the P trap of the bathtub drain. Note that there is NO odor leaking from the bathtub drain itself and that I have tried to put water into this overflow opening but it does not seem to stop this. Any insights into this weird problem is greatly appreciated.

Best, Truc Phan
