I found several places online that say it's OK to have a shower share a drain with a toilet, as long as the shower drain enters the stack above the toilet. Is this really correct? Might the toilet back up into the shower if the toilet was clogged? I've attached a diagram showing what i'm thinking of doing. I'm in a bit of a bind because I can't figure out any other way to vent the shower.
