Question on Venting
 
I'm pretty sure I am going to have to hurt someone! I had some plumbing done for my bathroom remodel since I have been working to much and needed to get it completed.

He finished yesterday and I had time to go review the work today. Correct me if I am wrong but unless something changed recently...Terminating the vent pipe in the crawl space is no bueno right? :censored:

Also, would using an AAV off a dual sink and putting it in the wall cavity also be incorrect?

That doesn't look like a vent. Is that a san tee behind it? That would be the vent and the 90 appears to be a toilet bend- ready for a flange at the floor line. I'm guessing 3" pipe..
As for the AAV- I very seldom use them and I don't put them in the wall without a louvered access panel.
What has the plumbing inspector said- there is a permit right?

Where I live, AAV cannot be enclosed behind a wall at all.

Also, I am not a pro but I am pretty sure it is not a generally accepted practice to mount waste pipes on a stack of left over 2x4.

Hope you did not pay the guy yet? I would ask him to pull a permit and fix and bring everything up to code.

ps. I haven't dealt too much with pex, but shouldn't those stub outs be supported by a blocking of some sort as pex tubing does not offer structural rigidity, unlike a copper tubing?

While I would never do something like that, the code only says the piping has to be supported, not how it must be supported.

:wink:


That looks like a friggin mess. AAV should be accessible if it MUST be used.


If that is a 90 left for a closet flange, I would think it would be temporarily capped or plugged...

wow that is not a legal a a v since it has a spring in it and here you are allowed to put in wall as long as it is accessible and breathable here is he i.r.c. on aav

also pex should be supported at sub outs

and no you can not just have open vent in crawl space

was this the plumber who name you found in a restroom stall

First of all , a aav installed below the flood level of a basin is definitively

a no-no. This guy doesn't know what he is doing. The work in the other

picture looks amateurish too (IMHO). The top of the closet el isn't parallel

with the floor. Fit up might be an issue. Only takes a little time and some

knowledge to do the job right. I'd part ways with this guy.:whistling2:

Water stub outs should look like this,

and AAVs must be accessible, usually behind a grill or access panel.

One question. What exactly is being vented in your crawlspace?

Javiles 09-12-2012 10:07 PM

Wow you need to get someone that knows whats hes doing, lots of mistakes, along with multiple code violations poor workmanship. get rid of this clown!

I hate I forgot about this thread. I had completed the rest of the bathroom myself because I hate trusting others to do work. If it's going to be messed up I'd rather blame myself and still have money in my pocket.

Anywho..I managed to get some of the money back. Unfortunately the company had great reviews everywhere I looked but I guess I could have done a better job on looking at their past jobs.

I think the main problem is that a lot of people pay people like this to do things but don't know if it's right or wrong. I semi have a clue how things SHOULD be done but that doesn't mean I want to bother with doing it.

I've been busy the last couple of weeks but I'm going to get all the pex fixed this week and put copper stubouts at the vanity and shower. I am also going to finish removing all the AAVs and running the vent pipes out the roof. Thanks for all the input!!!

Depends on what code you're using. Our says minimum of 4" above the trap outlet.
