Can anyone provide a picture or typical diagram? I'll need to make a long sweeping 90 degree turn, then a straight vertical drop before connecting to a horizontal drain line with a t/y combo.
I'll need to connect two sink fixtures and a tub drain to this line. I'm thinking I can use two AAV's for the sinks, then connect the tub drain (it's a claw foot in the middle of the room) to the vent line behind the toilet.
What I really can't envision is how the toilet drain has a vent on it unless the vent line comes from the piping that I drop down vertically through the wall on the floor below it. It doesn't work like a sink where you have a trap and then can put a T fitting and send the pipe up horizontally to become a vent. The toilet isn't working the same way so I'm having trouble understanding it.
Thanks.
