Working on my parents bathroom for them. House was built in 1990 in Ontario Canada.
Nothing is really moving all that much, tub and shower slightly, and single to double vanity. But, I have found that the tub and the vanity were never vented.
Shower appears to wet vent through the toilet, but I dont think that would work for the tub and the sink. I am a skilled DIYer, not a plumber.
I hope the diagram I did up quick makes sense.
The plan is to add the vents up the wall depicted in red, tie them together in the attic, then to the 3" vent stack.
My questions are:
1. Is this necessary? My dad said he could hear gurgles from the tub p-trap on toilet flushes sometimes
2. Does this plan work?
3. When tying the 2 1.5" vents together in the attic, should I go up to 2" for the shared portion?
