Would a bad AAV cause a bathroom or laundry room to omit sewer smells? We are getting a sewer smell a few times a week around 7pm.
It looks like the house has two venting systems. One goes through the roof and the other terminates in the attic with an AAV (it's about 1.5 feet above the insulation).
Last night I went to the attic and unscrewed the AAV and the odor just morphed out. I noticed the AAV had some condensation under it.
Is it coincidental that around 7pm a few times a week the water treatment plant smells really bad too? It's about 6-7 miles away from the house. I sometimes notice when driving home from work that the air around the treatment plant is awful until I'm a 1/2 mile away.
I'm thinking if worse comes to worse of installing a whole house p-trap as the house is on pilings and plumbing is very accessible.
