    So we have a brand new home that we asked the builder to include plumbing in the utility room so we could use as an additional sink when needed. I've installed the cabinets and was about to install the plumbing but noticed the p trap would be too low. Reminds me of this thread:
    https://terrylove.com/forums/index.php?threads/p-trap-install-stubs-out-too-low.68736/

    Except I have 2 pipes that come from the wall and I don't know which one is for what.

    So, first question, what are the two pipes coming from the wall?

    Second, can I use the AAV option from the above thread in my situation?

    Thanks in advance!

    It may be that the upper is for the p-trap and the lower for the cleanout.

    Terry,

    Thanks for the response, that would be great! I did shine a light in there and they are connected. Any reason not to just use it that way: top P trap and bottom cleanout?

    Reach4,

    Not at all. I just don't know plumbing and so I don't know if I put the cleanout at the bottom if it will cause issues with the p trap. I've read through some of the posts and saw that moving things around can cause venting issues, etc. If I can do it this way I will. Thanks for the help!

    I was just funning. I am not a plumber.

    The concern would be if the plumber put something other than sanitary tee for the upper fitting. I expect there is a sanitary tee in there, but I also expect there is a sanitary tee in the bottom. So if there is a sanitary tee in the bottom and even if a trap adapter has been put there, you will call it a cleanout.

    Is the bottom of that cabinet that you show far off of the floor? If not, I don't know what the plumber was thinking.

    I think the lower one is the cleanout.

    It could possibly be that the top is for AAV
    And bottom for the trap I've seen it done that way

    I don't know how they do plumbing in upstate NY, but where ever I done plumbing from 2 yrs in LA, 25 years in CA,
    2 yrs in N. Id, 4 yrs in W. WA. State, 5 yrs in SLC, UT and now 9 yrs in Houston, TX
    as a plumber that is the way plumbing is done if you stub out a drain it is connected to a vent not a AAV

    Alright another internet big shot plumber. Again I've said it's possible that maybe the plumber did that not for sure cause no one can be for sure cause u can't see the plumber maybe u see it in your genius head but again it is possible.And I'm from the city I've worked in all the borough's and currently Long Island NY. By the way it's a forum to learn and discuss not to show off how many years you've worked in the West

    Long Island is known to have really lax code inspections in certain areas

    Seeing gardners installing sprinkler systems with total disregard about back flow protection and homeowners hiring so called "plumbers" standing outside a big box store with signs saying plumbing

    Also there was a good old boys club where licensed plumbers from a neighboring town would cross a country line he would have his truck confiscated and sold at auction

    It was almost as bad a westchester as I held 4 licenses and finally Westchester adopted one code

    I agree that no AAV should be used and I agree with Terry

    I have seen new kitchens plumbed with the expectation that an AAV would be in an upper location. That would be three locations.
    Starting from the bottom,
    Cleanout
    Stubout
    AAV

    You have two there. Anyway, it would be fairly easy to open the ends of those pipes, you have to anyway, and take a look.

    Like Jerrymac mentions, older homes were never plumbed for AAV's.
