Hi I’m from Snoqualmie, WA (unincorporated King County). I’m looking for some drain/vent rough in help. I will post two pictures here. One of the way the plumbing has been done by a plumber. The other of just a blank canvas of what it is we’re working with. Forgive me if this is not the group for this type of stuff. (Please note the notations all around one of the images)
I’m concerned because although I hired a plumber to rough in this dwv bathroom (remodel project) the local inspector (king county, Seattle area, Washington) said he would rather see a wet vent... that would seem to me a major error on my plumbers part if this is actually absolutely necessary. He wants both the toilet and shower/tub be wet vented through the 2” vanity drain and he told me to look up wet vent bathroom group, and I didn’t understand any of it and none of the layout examples ever came close to matching my bathroom layout. Is a wet vent in my situation even possible considering the double lav is downstream from the toilet/tub?
However another inspector seemed to be OK with at least what I described to him over the phone with my venting under the floor, but something may have been lost in translation of course considering I’m just a layman. But I do believe he mentioned there are exceptions when doing venting horizontal if absolutely necessary.
(I should mention this is the same setup/layout as it was before. (except now lav on 2” drain/2” vent and went from 1 lav to double and before drain and vent were 1.5”) Vents have just been added under the floor. I cannot speak to how effective that dwv arrangement was as it was never used personally. Was all this adding of vents counterproductive? So, it would seem that before perhaps the tub/toilet were wet vented in the 2” laundry possibly?)
I’m competent enough to fix anything the plumber messed up, although I hope to avoid that/something major as we’re already out $1500 on him. If this can work fine, great, if something needs to be changed, let me know. Hopefully I can get this up to snuff if it needs the work done. If not great! I just want to feel comfortable tiling and drywalling over this if you know what I mean..
Anything I need to clarify let me know! Thanks!
