Where did you find that? That's a copy of my plan!

Just found this under "Drainage Piping": "One and one-quarter inch (32 mm) minimum diameter piping shall be required for one and not more than three individually vented fixtures." If I'm reading that right, having three fixtures on a 1-1/4'' drain pipe just doesn't sound like a good idea to me...

Thanks hj. Agreed. You inspired me to find this (not sure why it's taken me so long): "NFPA 1192: Standard on Recreational Vehicles, 2018." It has a detailed section on plumbing. I haven't read it word for word, but so far the only reference I can find on drain pipe sizing related to my question...

OK - thanks. Families with little kids and only one bathroom might argue with that, but I get it.

OK - thanks. It seems pretty straightforward. I'm curious why a full bath group with <1.6 gal. WC is 5 f.u. Do they not include the lavatory? Otherwise seems like it would WC, shower and lav, which would be 3+2+1. I'm wondering how they arrive at caveats like that.

This is ultimately about a 1968 RV I'm restoring but hopefully has enough plumbing concepts to qualify the forum. Since I haven't found anything to tell me otherwise, I'm trying to follow residential codes/best practices as much as possible in redoing the plumbing. Due to space constraints and...

I made a PVC joint in between a 3'' 45 degree elbow and a piece of pipe where I'm reasonable sure that the pipe is only about 3/4'' into the socket. The parts were primed and I believe there was a sufficient amount of glue involved. The location made it tough to get leverage and I just didn't...

OK - sounds like a "no" on the sanitary Tee. Two 45's would be acceptable, though? Also still wondering about the two 45 degree bends in the horizontal 3'' pipe. It seems like that might not be ideal, but I can't see another way to do it. Also - if anything else in the plan looks off...

My fault, really. "After" should be on the right. I figured that out after I was done, but it was too late. So, just to be clear, with the 2'' pointing up, I can definitely use: http://images.lowes.com/product/converted/611942/611942035694lg.jpg But what about a sanitary Tee...

Thanks for the reply, Redwood. Would this be an acceptable unit: http://images.lowes.com/product/converted/611942/611942035694lg.jpg

Thanks bnitsuj007, glad to be of service. Anyone else able to comment?

As this is my first post, let me first say that over the years I've found plenty of useful, candid advise on this forum - thanks all. I need to replace a section of 4'' CI waste stack and lead closet bend in an "older" house, and hope that someone will be able to tell me if I'm on the right...
