attached photo - We are looking from the floor below the bathroom being remodeled. the new bathtub is over our head and I am looking to run the drain line.
(C) is the existing p-trap for the shower with (A) being the vent up and drain down.
Two plumbers have told me they will tie the bathtub drain into the existing shower drain going through joist at (E) and tieing in behind the joist (D) and use existing vent/drain (A).
Shouldn't I run the bathtub drain through joist at (E) and run to (B) with a vent that will tie into the vent (A) halfway up the second floor wall and 90 to (A) for the drain? 1/4" slope per foot
Can I tie into drain at (A) with fitting one on top of the other or do they make a fitting that will tie both into (A) at the same level?
