Hey everyone. I've done some personal DIY plumbing here and there, mainly finish stuff or modifying existing. My BIL wants to add a bathroom to the house he purchased and has enlisted me to help. He's handling all the framing and boarding/mud/tape/etc, but I am up for the wiring and plumbing. Wiring is no issue, but I keep flip flopping on the best way to plumb this thing.
It's going to be a fairly easy layout. Lav, WC, Tub all on one 2x6 wall. We can install a new vent wherever through the roof. Joists run parallel to this wall so we can keep the 3" pipe nice and tidy up in the joist space (hopefully). The run isn't too long before we need to turn and follow the bulkhead so we should be good on slope.
I attached a picture I found online, but it looks like the gold standard for plumbing. Everything is individually dry vented and honestly seems a little overkill. The differences with my BIL's layout are its going to exit to the right of the tub (this picture it's on the left) and his will run parallel to the joists (this runs below the joists which are perpendicular). Flipping the bottom of the picture is easy enough, but the biggest issue is the space required to vent the WC.
Oh as for dimensions, it's going to be fairly small. 2x6 wall consists of 30" for vanity, 30" for WC and 36" for tub all side by side (8'x5' bathroom).
Should I be looking at just dry venting the lav and then using it as a wet vent for the WC? I assume I'd need a 2" vent in that case? Or do I just wye in another dry vent after the WC? Can I eliminate 1 or 2 of the vents in this layout to ease installation? Any other suggestions? We're in Canada if that matters, but I don't think this will end up being inspected anyways (still want it done right though).
Thanks!
