grey tank stink
Recently the motorhome stinks whenever we run any water to the grey tank: washing dishes, showering, etc. I couldn't figure out where the smell was coming from. I thought maybe it was coming from...

Air Admittance Valves under kitchen & bath sinks would really smell inside those cabinets
Stink from A/C Vents...grey tank roof vent leaking vapors into attic space which is being pulled into A/C duct work
Grey tank vent line may have slipped down below roof line which would expose attic area OR vent line is cracked
Running water stirs up grey tank contents and as water goes in air has to vent out so there is an increase in vapor flow
Tape a plastic bag over air admittance valves as a test.
A/C ON..run water down sink drains and see if you still get grey tank odors.
No odors.then AAVs are bad
Still getting odors...grey tank vent line issue
