Hello everyone, this is my first post. I just wanted to say I have found this sight invaluable for advice through the years, I just haven't needed to post a question before that I wasn't able to answer by searching. I am located in Canada for code reference, though I would be happy to accept advice based on the UPC if you are unfamiliar with the NPC.
The plumbing diagram below is for a mother-in-law suite attached to my house. The drain lines are how things are currently plumbed. There are currently only two areas with venting. The main floor toilet (which I'm not sure is vented ok) and most likely the three basement fixtures (which I'm fairly sure are wet vented but the drain lines are beneath the slab and I don't intend to check unless it causes me problems down the line).
This is not a pretty setup, but I want to make it function right while changing as little as possible. I have a few questions about my proposed diagram below.
1. Do you see any code violations in the drainage setup? All pipes have a proper 1/4" slope.
2. Is the venting for the main floor toilet acceptable? I have never seen one done this way before.
3. Any red flags in the rest of the venting?
4. Does anything need to be changed/added?
Thank you for your time,
Kurt
