This is a new washer/new doublewide trailer.
I have an aerobic sewage system. The laundry room has a distict sewage smell when the washer is in operation. This is the only place in the house this is noticeable.
I have looked in the pipechase and there is a p-trap with no leakage. I cannot see the break to the vent pipe so can only assume its working. There is no problems with the washer's discharge draining.
Any ideas?
