    Just got new granite counters and of course, new sinks to boot.

    Went to reinstall the garbage disposal and even with the P-Trap all the way up the garbage disposal discharge tube I am about 1.5 in low on the wall side of the wall bend. I really don't want to cut in the wall to lower the drain pipe. Have found multiple P-Trap extension tubes, but I need it on the wall bend side, not the P-trap side.

    Can't seem to find anything that will extend the wall bend (down, not out) and I'm running on one sink right now with an impatient wife to boot. Took a picture of the problem - see attachment.

    Anyone seen this problem before and can make a suggestion on how to fix without digging into the wall??

    Many thanks!

    Almost all new granite counters with new deep sinks have the problem, and yet the kitchen remodel outfits act like they've never seen it.
    Normally if a customer is getting new countertops, I suggest lowering the drain 3" in the wall before the cabinets go back in.

    Of course you can mickey mouse it by flipping the bend and creating a deeper trap, this way to tough to keep from falling off, or you can buy solvent weld plastic fittings and glue something up. In otherwards, Mickey Mouse it.

    Dearborn makes a trap that can be reversed.

    It would be nice if we could get a smaller picture of the entire space inside the cabinet, including the drain for the sink you are using.

    Terry pretty much nailed it. You should have lowered the drain in the wall while the cabinets were out, and your cabinet company should have forseen this situation. Happens all the time.

    If you make the trap deeper by cobbling it together, it will always drain too slow.

    It will not drain slower, but a "reversed" trap "J" bend will be difficult to keep from coming apart when it is bumped.
