re: Aren't wet stacks only allowed on the same floor?
I hope not! My 2nd floor bathroom, 1st floor sink and 4 basement
fixtures (full bath and utility sink) all use the same wet stack.
There are no dedicated vents for any fixtures in my house.
The 1st and 2nd floor fixtures drain into the cast iron vertical stack
and the basement fixtures all connect to the cast iron drain pipe
under the slab. Everything works fine as far as I can tell. The only
drainage problems I've ever had in 24 years were caused by roots in
the town owned section of the drain out by the street.
