Tank Smells, But Not From The Tanks Themselves
Trailer is a 2001 All American Sport.
Problem- We get a wretched tank smell every time we run water down the sink, and to a lesser extent toilet flushes. I can't find the source, it's not coming from either of the sinks nor the toilet. It just hangs in the air. It's primarily in the living area, not the bathroom. The traps are clean and don't smell or have any debris.
We're in Phoenix in July, and the A/C is running a decent amount. I noticed we only catch the smell when the A/C is on, and there is no smell when it isn't.
I'm beginning to wonder if the A/C unit has a fresh air intake near enough to the tank vents, that it can draw in the tank smell when it's pushed out by the incoming water? If so that strikes me as another glaring design flaw, but I'm not sure what I can do about it. Has anyone else experienced this? Is there another source of tank smell that I should investigate?
