Going through this because the bid we got from any local plumbers was over twice what we were expecting, so I'm buckling down and taking this on myself. I have no concerns over the actual work but want to ensure I've laid everything out properly.
Appreciate any insight! I believe I have everything correct but want to ensure I do before proceeding
- Current DWV is all cast iron. I'm planning to replace with PVC. No particular reason for PVC over ABS, I just see PVC used by many and it's more readily available around here at big box stores
- This branch is for a single guest bathroom sink and a single toilet
- The drawing has 2" and 1 1/2" written for the sink branch (vent and drain); I plan to use 1 1/2" as I understand that's what is required by UPC and there is no need for 2"
- IMPORTANT: I didn't draw this, but the current vent is directly above the sink vent line (opposite of what the drawing shows, don't ask why I drew it that way). If the incoming vent from the roof is 2" I'm guessing I can use a 2" x 1 1/2" x 2" sanitary tee so that the incoming vent is 2", the vent straight down to the sink is 1.5", and the vent going right towards the toilet is 2"?
- I believe main line is a 3" cast iron but I need to verify
