I have a single SVP that extends through the roof of my house.
I needed to free up that particular section of roof for solar panels so earlier today I cut off the pipe in the attic and replaced it with an AAV, as I was led to believe from the website at https://www.jdpipes.co.uk/knowledge/above-ground/soil-vent-pipes-vs-air-admittance-valves.html that I didn't need open ventilation providing my neighbours on the same sewer run have open vents.
I now have a faint sewer smell in the upstairs bathroom but it doesn't appear to be in the attic (although not sure I would smell anything as roof tiles are still off so there is quite a lot of ventilation).
Have I done anything wrong here? Could it be siphoning water out of the sink or bath trap?
If an AAV can't be used, is it possible to vent out of one of those plastic vent tiles or a vented ridge tile? Or would that make the loft smell from gases making their way back in?
