    Kitchen Sink with two horizontal drains
    :confused: Bought a house recently. Kitchen sink a mess.

    I have never seen a kitchen sink with two drains; one per basket. Each basket has a tailpiece and P-trap that goes to the horizontal drain pipe. I hooked up my new sink the way the old one was and I am having a lot of trouble.

    I can drain the righthanded sink and it will bubble out the left drain pipes or leak out the dishwasher nipple on the leftside. I recently hooked up the dishwasher think it was just pulling a vacuum there... I'm still having problems.

    I checked the ven pipe on the roof... seems okay... Any ideas? Should I just T them together and use one drain? Cap the other off?:confused:

    This sounds like a normal hook up for a double compartment sink. Two traps connecting into a wye under the cabinet.
    It sounds more like you disturbed some crud in the lateral, (horizontal) line in the wall and now it's backing up. Remove the "J" bend from a trap and send a snake up into the wall. You will hit a 90 about 8 inches in but once past that you only have to put out 6 more feet. I hope you installed a high loop in the diswasher hose when you installed the dishwasher. Regards, Tom,
