Hi I write in despair.
I live in a mid terraced house with a ground floor extension on the back of the house housing the kitchen.
We have a downstairs bathroom with shower, sink and toilet.
For the past few weeks, we have been smelling a drain/sewer type smell from below the toilet and in the hallway. We have lived here for 10 years and the bathroom has been here that long. The downstairs bathroom is in the original part of the house on wooden floorboards (suspended) accessed from the hallway.
There is an AAV which just remains closed when flushing/not flushing (no change with a plastic bag over the top).
The water from shower, sink and toilet all drains fine and quickly as they should do, no gurgling or spluttering. The s-trap under the sink and shower have water in them and the toilet has water in it (i.e. does not loose overnight)
From the toilet, the soil pipe runs straight down under floor boards (3ft) and then bends into the extension where you can’t see it anymore, assuming it goes to man hole under the concrete kitchen floor.
Just under the bend before entering the extension the soil under the soil pipe bend seems damp but by no means wet – this may be normal or not, however the smell of the soil is as it would be in a garden (sorry, trying to be as informative as possible).
Could it simply be drain smells, coming out from the ground, is there something like a wax ring that might have failed in the toilet, could it be a crack in the soil pipe.
I am somewhat confused as the smell is intermittent, and no problem with flushing, however unsure as to why the AAV is not opening and closing.
The smell is more like drains/cat wee and not human waste.
Sorry for the essay but wanted to be as informative as possible. The wife is having nightmares about kitchen floor being dug up!!
