Thanks Wayne, I'll take your posting advice to heart next time. You're right on the plumbing details. Now that I'm at least in the ballpark (drain and vent relative to island leg), I'll mock up and fold in the details like the cleanout. I think the details below the floor will workout okay...

Thanks! I know this layout well. Now the question is, does the code restrict the length of the two diagonal pipes between the 90 bend at the top and the two 45s? If not, then I'll cut them to aprx 11 inches in length so that the space between the drain and the vent is enough to fit down my...

That doesn't surprise me. In this case a sloped drain seems better than a horizontal vent.

Hi John, I was afraid of that. Still searching for a solution... At what point can the vent run horizontally? Or, can a trap arm enter a sloped (but by definition vertical) drain pipe? Other than an AAV I can't believe this problem hasn't been solved before. Thanks!

Does an island loop vent have to come to a point (45-90-45 bends), or can the top run horizontally for a few feet using two 90 bends and no 45s? I would like to run my island sink drain pipe down one leg of the island and the vent pipe down the adjacent island leg a few feet away. Thoughts...

I also understood that sewer and water could be side by side (in CA with correct pipe). With pressurized drains that doesn't hold true, the question is how much pressure do you need for it to be a "pressurized system." My guess is it's a lot more than the 10.8psi my sewage lift pump produces...

Thanks John. I appreciate you providing the ASTM standard!

Thanks. I just found out that the lift pump I'm considering only produces 10.8 PSI, not much at all. I have pulled a permit and just started a conversation with my inspector. Thanks.

You're absolutely right. I finally got through to my distributor. Only foam core is available in CA. I could special order it but I'd have to buy some 3,000 feet. Solid core PVC may be the way to go. Thanks again!

I'm installing a sewage lift pump and 2" ABS pipe from my garage up to my house (and then out to the city sewer line). I'm having difficulty getting a clear answer to four questions: 1) is foam core ABS okay in a trench (18" deep in my area) or should I use solid core ABS, 2) same question...
