Thanks for the reminder. I am going to put it up last as it would reduce my mobility crawling around under there. No need to worry about any clothes since it's a crawl space lol.

Yep, that's what I have.

Yes, I am trying to correct someone else's work. Could I just try and cap the pipe where the AAV is? or do I need to just rip it all off and re-do it correctly?

I'm pretty sure this is incorrect...if I'm wrong that would be good.

But if I'm not what's the best way to handle this? Could I just try and cap the pipe where the AAV is? or do I need to just...

Exactly...and I would have rather had someone else do it but the last one turned out to be an idiot. :-\

Oh yea. You get to thinking about things too hard and forget the easy things. Thanks!

Would either of these setups be better than the other? It's for a tub/shower combo.

*Bump*

Looks like some 22.5 degree elbows would work better with the previous picture I posted. Any suggestions?

Would this work? Black = Drain line, Red = Vent pipe, Yellow = Approx floor joist location

Excuse my terrible drawing. Basically a wye for the vent to come off the drain line from the tub and...

Yea...good times. Perfect reason why I have done everything myself in the past. Just haven't had time to mess with the plumbing.

I've got another question. I have two different places to run a...

Lol, I just noticed that too. Definitely not planning on giving them the rest of the money until they fix all of the issues.

Well the sad part is that there is already a vent exiting the roof above the area where he just left it in the crawl space. He said that he just capped the vent on the top of the roof and didn't...

Running the pipe to the attic and using the AAV up there would be acceptable though right? Also, did you agree with the vent pipe terminating in the crawl space in picture #1 being COMPLETELY wrong?

So I had someone finish some plumbing for me since I have been too busy to mess with it.

He finished yesterday and I had time to go review the work today. Correct me if I am wrong but unless...

How bad is it that none of the plumbing supply stores I've called so far have even heard of the double fixture fitting? Looks like I'll have to order it online.

I originally planned on using a fixture fitting tee but I read a couple of posts that said not to? I thought 3" for the toilet was common? Are you suggesting a 4"?

This is what I was going...

How does this look? or is it completely messed up.

Yea, it's IPC...the link to it is http://ecodes.biz/ecodes_support/free_resources/2012NorthCarolina/Plumbing/12NC_plumbing.html

Maybe that would explain why the toilet didn't have it's own vent...

Searched but couldn't find my answer. I know(think) a toilet needs a 2" vent but is it acceptable to start the vent out as a 1 1/2" and then increase it to 2"? I have 2x4 framing and didn't want to...
