drain odor in bathroom sink
Posted by Dorothy Langendorf on March 12, 19100 at 19:52:01:
My downstairs bathroom has a terrible odor emanating from sink drain. The j trap is clean and
has water in the trap. When I run the water with the drain closed, there is no odor. When I open
the drain and the water flows through, the odor is bad. Any ideas?
