    I need help with a kitchen sink drain, we had a new granite counter top and sink installed, I had the sink sent directly to the installers for proper fitting, didn’t realize they where sent the wrong depth sink till after everything was installed, Sink is 9 inch deep not the 6 inch I ordered. My drain inlet is to high now to connect both sides of sink to current drain. I could possibly hook up one side of sink with a very short tail pipe piece, the other side I was wondering if I put a 45 wye in the vertical drain stack in the basement, I could add another drain line up to the other side of the sink and also get a dishwasher wye in for a new dishwasher we want to install along with an AAV required now by MN code.

    You might want to consider removing the 45 near the wall and installing a wye there to pick up the two bowls.
    Having sinks that are that deep makes things harder and you need to be more inventive.
    Having baskets that take less space helps too.

    Thanks for your suggestions, unfortunately even with shorter baskets the piping leaves me no room to get the dishwasher wye in and no room for a dishwasher tail piece either. I opened up the wall more and the 45 near the wall is really a wye 45 and a 45 degree coupling connected to some other pipe I think it might be an up line vent.

    I’d like to cut the metal pipe in this area or in the white circled area. I’d add a small piece of pvc to the wye and add a rubber couplings to the top and bottom existing metal pipe. The little green line is the 45 wye

    I have a concern about the pvc pipe being right up next to the hot water pipe running up to the radiators. You can see in the yellow circled areas that the current metal pipe is almost on top of it and I wonder if the PVC would be effected by it.

    A small section of the pipe in the basement was replace before due to rusted out coupling. I would just rebook up to that splice on the lower end.

    Again thanks for the help

    I would jog around that in plastic with a pair of 22.5 degree bends.

    Alternatively, you could put a section of 2 inch type K copper pipe in place, with the appropriate couplings.

    Type L may be thick enough
