Hi,
We have a soil stack that smells and I just wanted to run my suspicion as to the cause by everyone here before I punch holes in ceilings!
The toilet in question has a soil stack in the wall that goes into the roof space. In the adjoining room (same wall run) I took out some of the plasterboard as I'm running cables. At this point the room was filled with sewer type smells. There's no evidence of any "wet" leaks just a strong whiff.
I went into the roof space and it too smelled yesterday but smells elsewhere in the house. I suspect it's the air admittance valve - would this be the likely candidate?
The roof space it's in is visible from the main loft but I cannot fit through the gaps so I'd need to go through the bathroom ceiling.
TIA
