That's awesome! Such a great idea.

Ahhh! Both comments make perfect sense to me. Thanks again Wayne, and everyone else who commented. You guys are lifesavers!

Wayne! Thank you so much for the awesome comment, I completely forgot about the horizontal dry vent. (On that note, during all of this research I've been perplexed as to why a horizontal wet vent is allowed, but a horizontal dry vent isn't). I made a quick sketch of the revised plan as I...

My apologies, I should have better explained the "Addition" line. That 3" line comes from an addition that was built onto the house in 1992. It has a shower, wc, lav, and laundry on it. The issue was that it ran through the headspace of what I would like to be finished space, so instead, I'm...

Thank you guys for the replies! So already existing is a backflow preventer outside the house, between me and the main sewer line. But I am fond of the idea of having a backflow preventer between the basement plumbing and the rest of the house. I also have been really firing from the hip on...

Ahh that's an awesome idea. Thank you for the reply. Ok it sounds like I need to re-think this entire design. I want to do it by code and proactively avoid any plumbing issues. Preferably BEFORE it's buried under concrete, haha.

Thank you for the response Wayne! The "new addition" line unfortunately also has a WC on it. I could maybe spare 5-6 inches in height, but unfortunately I think that wye to transition between the lower and upper line will push the WC far enough left to be awkwardly placed (the idea was the have...

Thank you for the reply! The system thankfully already has one just outside the house. Although I am looking at options for the shower drain, as any internal clog (especially at the backflow preventer) will hit the shower drain first.

Shoot, okay. I appreciate the candid response. Do you see any way I could reasonably make this configuration work? The toilet and shower straddling the main line seems like a challenge. Also, I thought I had mentioned it in the original post, but it looks like I totally neglected to mention...

My county follows IPC for plumbing code. My basement currently has a decent amount of concrete busted up for a separate project so I'm taking advantage of that to run plumbing for an eventual bathroom down there. I'm worried what I've done isn't to code, and would love a second opinion. In the...
