Hey
So - taking out built in tub to replace with freestanding - need some help on the wet vent as think what is there is weird/wrong. Thanks in advance - learning a lot as an first timer.
Currently there is a 2" 12 ft wet vent running from the shower to the main 3" wet vent - and the tub 1 1/2" drain wye's into that BUT the trap arm drops 5" over 4ft (it's a weird routing with a 90 degree and other turns).
1) I think this drop is too much for code - should be 1/4" per foot - correct?
2) Is it ok for the tub to wye into the shower line, rather than direct into the main 3" wet vent?
Assuming I am correct - I think I should;
- cap off existing wye (it would be difficult to remove as very close to the 3")
- new 1 1/2" drain - with drop of 1/4" per foot
- should this 1 1/2 drain wye into the 3" or the 2" or either
Crappy diagram and photo attached
Also curious if anyone has any ideas why it would have been done like this?!
Appreciate the help
