Justin, et al,

I don't see how venting can possibly be the problem. To run into the
shower pan, there MUST be liquid up to that level. H20 being a bit heavier
than air, even if the tank had no vent (which it apparently now has two of,
the original and the newly added one), the water would STILL go to the
bottom of the tank, not up into the shower. Admittedly increased pressure
in the tank MIGHT force a little bit, maybe a cup full, of water out of the
P-trap, but no more.
