I have a victorian house with a septic tank - a large tank with soakaway.
My main bathroom's has an intermittent smell of sewer gas. We've removed an AAV from under the floorboards believing it to be the problem. A second AAV exists in the chimney stack of the bathroom.
The smell returned so we ran a vent pipe from our 3rd fl attic bathroom out through the roof (we did'nt have a vent pipe so believed this would solve the problem). However, the smell has returned smelling more like stagnant water than gas.
I am confident that the smell is not due to lack of cleaning.The toilet pan has always (2 yrs since fitting) had this 'stagnant' smell but seemed a small issue compared to the rotten cabbage smell. However, this smell is now filling the bathroom.
My builder suggests we run a 2nd vent pipe directly from the soil stack out through the wall and up to the roof . I am running out of ideas and may have to have the limestone tiled bathroom destroyed to find the fault.
Running water into the basin, bath and shower traps, hasn't made a difference either.
Our downstairs WC, and other bathroom on the other side of the house have no smells just the main bathroom.
Any suggestions? Thanks!!
