Looking for diagram or picture that shows rough in ABS pipe installation in new concrete slab that is not poured yet. Trying to accomadate a toilet and vanity. What size pipe do I need coming up for the toilet? 3" or 4"
the top of the pipe should be flush with slab or recessed?

Is there some type of flange that should go in the concrete?

Dave,

Is there a software program that allows one to put together computer generated rough-in drain line system? Realistically all I need is the dranage system and don't need all the bells and whistles that I find in most CAD facility software.
Thank you in advance for your help with this...

Tim,

I had a problem the other day. Let me start by saying that I have a new house. My upstairs bathroom toilet was clogged so, when I unclogged it I went downstairs. About 2 min. later, water started to come out of my ceiling fan. What's going on? It wasn't fresh water but drainage water. Did I plunge to hard or what? Is it possible that I plunged so hard that some water came out of some vent or something. I don't know anything about plumbing. My upstairs toilet is almost right above my ceiling fan if this helps you out.

Thanks,
James
