I'm redoing our master bath and as part of the remodel we are swapping the location of the shower and the tub and making the shower bigger. The shower has a 2" drain and a 1 1/2 vent coming off the drain line and up the wall to the roof. The tub has a 1 1/2 drain that dumps into a 1 1/2 pipe in the wall that is also vented through a 1 1/2 vent to the roof.
Can I dump both the shower and the tub to the 2" drain and then connect the vents as shown in the attachment? I believe I need to give the shower its own vent line since it is outside the 5ft distance for the 2" wall vent. Points I would like to have verified
1) Can i run both the shower and tub to the same 2" drain (sloped 1/4" per foot)
2) Is it necessary to use a 2" ptrap and drain line on the tub since it is more than 3 ft from the vent
3) Should I use a Wye fitting to connect the tub drain line to the drain from the shower? Is there a better recommendation?
4) When running the vent for the shower off the 2" drain line what do I need to think about? Does the vent need to stay vertical until it is 6" higher than the shower drain or the tub overflow?
What else am I forgetting?
Thanks for your advice
