I have lived in my double wide for about 5 years now. The first winter we went through in it, a horrible stench started coming from our master bathroom. I mean unbearably bad here. We searched and searched but could not find the source, so I we just assumed a rat crawled up into the insulation under the tub and died, so we would just have to wait the smell out. We sealed off the door to the master bath and ran the exhaust vent 24 hours a day. It took months, but it went away. The next year the smell came back with a vengeance. Again a futile effort was made to find the source, and again the bathroom was sealed off. Year after year, the same thing, but only in the winter.
I always thought the smell might be sewer gas, but having done some plumbing, I understood the pee-trap system to prevent sewer gas from getting into the house. I ran water in the sinks to make sure the pee-traps were full and checked the vents on the roof for blackage and all was well. But still the stench was there.
Each winter has been the same. But at long last I think I found the culprit. It is this thing. I have never seen this thing before and I don't know what it is, but it appears to be some kind of pressure relief valve that is letting the sewer gas into the house. This is a modern house that was built in 2010 and I don't understand how it could even be legal to install a device that would let sewer gas into a living space.
Can anyone tell me what this thing is and how it works, and why it lets sewer gas into the house Only in the winter time?
