    Hello,
    I have an unfinished basement and opted for the 3 piece rough in versus the 2 piece rough in. I have 3 pipes sticking out of the concrete basement floor, (1) larger one assume is toilet, (2) 12" behind the toilet along the wall is a 2" pvc pipe, (3) then in the middle of room is another 2" pvc pipe.

    I assume(1) is toilet, (2) is sink drain, and (3) is shower drain. However, I can tell if (3) is in fact for the shower because unable to see if there's a p trap below grade. Is it possible that they would have put a p trap some 3 feet away under or near the toiler drainage, and then into my sump pump container located below grade ?

    I poured water into the shower drain (3) and the water ran out into the sump pump container. I'm just concerned that perhaps (3) is not a shower drain, and furthermore, that (2) is not a sink but rather a vent for the toilet.

    Any help that can be

    If it was roughed in for a shower, then yes it would be out from the wall a bit. Poor water down the pipe and if you see it there is a trap.

    Thank you for the reply. I already poured water down the drain, but couldn't see the water sitting anywhere, so there's definitely not a trap directly below the shower. I'm not sure if they would have put a P trap further away, near the toilet / sink plumbing, for whatever reason ?

    Are there any tricks to figure out if there's a P trap in the system somewhere ?

    Sounds like you built the house. Can you ask the builder what was done?

    The only other trick is have a drain cleaning company run a camera in. I doubt if they put a running p-trap down the line though.
    You might have to break up the floor and put a 3" ptrap in.

    Is that sump pit for more than your basement?
    How many lines enter the pit?
    I have arranged a sump pit to act as a trap for various municipal/industrial applications. Don't know if it's legal for residential.

    Blow into the pipe, if air comes out the other end, no trap.

    If that is a shower line going into a sewage pit then it must have a trap put in.

    You can get a waterproof inspection camera very cheap.
    I’m not saying to get this exact one, just posting a link to show what I mean.

    I got a nine foot waterproof snake type camera a few years ago, I use it for all kinds of jobs where you want to see into a wall, to look before you plan a route for plumbing or wiring,
    Or behind or under an appliance, into a ceiling, whatever.
    It beats cutting big holes that need patching.

    If you buy one to see if you have a trap, you will use it again many times.
    Or maybe you can rent one, but they are cheap.
    The one in this link is about $40.00.

    And yes, post pictures!

    Is there some way that “Always Include Pictures” advice can be posted to this site, on the sign-in page, in giant flashing letters?

    Maybe it is there, and I missed it.

    Hello everyone, thanks for the replies. Attached is the picture. I am essentially standing on top of the pit where the sump pump will be located.

    To answer a question from another response, there is only one pipe entering the pit, and assume all 3 pipes sticking out of the ground are connected under the ground and eventually the pit. As mentioned previously, there is definitely NOT a P trap directly below the pipe that is in the middle of the room.

    The clowns that put the rough in some 15 years ago, placed the toilet about 2 feet from the wall, and may have put the shower pipe in some other area that I was not happy about, so they re-did the plumbing hence why you can see new cement work. At any rate, I just need to know if the pipe coming out of the ground (assuming the shower one) has a P trap somewhere in the system which is compliance and correct.

    Thanks again all .....

    That pipe in the middle of the room, if it is going to be a shower, needs a p-trap right there as code requires.
    Also, I highly recommend Liberty sewer ejector systems. I only recommend the duplex (twin pump) system. It comes fully pre-assembled, and includes the high water alarm and electronic panel.
    Do yourself a favor and only get a duplex system. IMG_5497.JPG

    insert your measure tape into the pipe you believe may be the shower/tub drain

    you can ease the tape down the pipe, you can ''feel'' if you are going into an elbow or a ptrap
