I am installing a new linear shower drain. What I hope to do is install the new drain upstream of the 1.5” dry vent, however there is already one 2” vented drain that discharges just above the vent (originates at my washing machine).
Reading code 909.2, it appears that I should not install the shower drain onto the 3” main wet vent where I hope to.
But really, the washing machine wet vent drain is rarely with water so it’s pretty much a vent, right . This is my attempt at trying to justify why I should go forward.
Attached is a diagram that has a”blue” wye where I want the drain to connect and a photo that shows the wye and ptrap approximate positions. The other photo includes the vent in the wall, the clean out, and the overall layout where the tub and shower were (capped fixtures now).
I have also considered running my new drain arm into the old shower drain arm but that would require a lot more concrete destruction. Not my first choice.
I thank you all for any advise on my ideas?
