Please reference the attached image of my sketch for the questions below - thanks so much in advance for your help. The long sweep combo is tilted at 45 degrees to get to the wall, then 45 to get it back vertical again in the wall. Do I need a clean out above the 45 above the floor? Can I use...

Great, thanks for the clarification

So to clarify, I could have a 1.5" trap/arm going into wall with a 3x3x1.5 santee, even if the lav is the only thing on the branch?

I have a (hopefully) quick question that I haven't been able to find a straight answer on.. When I put drain pipe in for a lav, code (UPC 2009) requires 1 1/4 in. I've heard you can go up one "nominal" size (so I think that would imply going to 1 1/2 in.). What if you want to grow to 2" or...

Hi all, I got more planning done on my DWV project this week and I'd just like to run it by everyone and see if anything is glaringly obviously wrong (UPC 2009). The images I attached don't show the connecting pipes, but the fittings and relatively close position where I'm thinking about...

Thanks Terry, that clean-seal looks perfect and I'll see if I can find one. jadnashua, I was a little concerned over the slope because I've seen conflicting advice in other forums, such as "Water can run away from solids leaving them stranded" and "If you need to exceed 1/2" per foot slope...

Here is a good example, is this considered horizontal or vertical? If horizontal, can it have more than .25"/ft slope? If vertical, what makes it vertical and how long of a run can this be at 45 Deg? (UPC 2009) Thanks

I may have found something that could answer my first question. I found an inflatable plug that I could stick into the pipe provided I have a wye installed. I attached a picture of it to this post. It wouldn't test the ABS to CI interface but it could do the rest without the need to detach...

Hi, I've been learning a lot from this site, but this is the first time I'm posting. I have a couple questions related to a job in my home that I'm going to do. I have not done any work on it yet, but I'm trying to plan this all out so I can do quality work and do it quickly. I'm going to be...
