I have a sewage smell in the bathroom that has been there for weeks.
I have checked all the traps and none are dry. I have checked the drain from the bath and it is clean, no sludge at all. The seals that I can access all seem good around the toilet.
I want to try a smoke test to see if this helps locate the source. I was thinking I could open the manhole outside in the garden, block off all exits except the bathroom and drop a smoke stick in there. Would that work?
The main stack has a one way valve on the top, inside the boxing. It does not vent to the outside.
I read on one forum that smoke tests can be bad for plastic pipe but it didn't say why. Heat? The manhole has clay pipes so only the smoke would get to the plastic inside.
Thanks
