Thanks - we tried that but the smell comes back. If we haven't used the bathroom sink or bath for a few hours then when we use it the smell comes pouring out of the drain. It smells like sewage.
Thanks Nige F. Two plastic pipes come out of the bathroom wall and into an open metal pipe which runs about 2m down the wall to an open drain. Out plumber suggested sealing the open drain. But we worry that that might force the smell up into the bathroom?
Do you think we should seal the...
Hi
We have really bad sewer smells coming from the outside drain where are bath and sink water go. The smell comes intermittently after usage. I have cleared the drain of debris. There is no blockage according to DynoRod. We are at a loss - help please!
