Your issue is 'physical' in that the vent line gets blocked by level in tank.....chemicals/foo-foo odorants won't resolve your problem
When vent gets blocked off pressure builds every time you put more water in (sink/shower etc.) as water is heavier than air so the air has to get pushed out.
The air admittance valves are designed to CLOSE under pressure (unless worn out and don't seal) so the air gets pushed up thru 'P' trap.
Tying into the vent line portion (not drain line section) will allow air to escape tank as water drains into it....even if it goes downward and out thru floor.
Not the most ideal corrective or conventional measure.....but easier than dropping tank, pulling vent line and cutting it off then reinstalling vent line/tank PITA!!!
Is there enough room on vertical section of stub pipe where air admittance valve is installed to cut and put a 't' in???
Mine stub pipe is very short
