Form has been a great resource but can't find an answer to what may be a simple question.
I'm re-plumbing a basement bathroom and Utility room, running all drain lines below the slab (original not permitted and very sketchy).
From the main stack moving upstream the order of the fixtures /tie-ins are as follows: The main line to the sewer is 4" and the lien I intend to run starts as a 3:, ends a a 2".
Toilet - 3" into a wye into the 3" new line - within critical distance of the stack, no secondary vent
Lavatory - 2" to wye into 3" new line - seperate 1.5" vent line run in wall to main stack vent tie-in
Floor drain - 3" P-trap to 3" line to wye into 3" new line - no vent, within 12' of main stack as per my code/inspector (Alberta Canada) new line reduces from 3" to 2" upstream of the wye that ties in the floor drain
Shower - 2" p-trap to wye into 2" new line - vent is 1.5" line 2' upstream of shower tie-in wye (this is part of my question)
Clothes Washer / Lanundry Tub - 2" p-trap below grade into 2" line - vent is same vent as described for the shower, but washer/laundry tub p-trap is within critical distance of the 1.5" vent.
Diagram is attached.
My question, is there an issue with the washing machine/laundry tub and the shower sharing the vent where that vent is 3' downstream of the laundry p-trap and 2' upstream of the shower p-trap? Is the 2" line large enough to act as a wet vent for the shower for that 2' horizontal run?
Effectively the laundry vent is downstream of the lanudry p-trap while the shower vent is upstream of the shower p-trap.
Thanks,
Jeff
