I have a vent stack in the inside wall of the water closet in my MH. When I flush, I notice an odor coming from cutouts for electrical panels on this wall. Does this mean I have a loose stack down where it connects to the tank?

Bob, it sure sounds like you may have a loose stack vent. Have you check to be sure the vent is not clogged with mud dobber, wasp nest or other debris?

Hey, that sounds like a possibility, doesn't it? I have caps over the stack tops, but not sure how they come off. Friction fit, I assume.

As for looseness, I can feel some play in the stack pipe about 5 ft. above the top of the tank (in the wall), but this could also be due to the thin wall material. (Sewer and drain pipe)

There will be some play in your vent stack pipe even if properly installed, at least there was with ours. When I installed new covers on our vent stacks I noticed that the pipes aren't really attached to anything up top at the roof line. And after removing the original factory vent covers the pipe had a lot of room to rattle around in through the hole in the roof!

When I say loose, I don' mean above the tank I mean the fitting connection(s) on the tank. THey must be an airtight seal or gas will come around them.
