    hello,

    i am re-plumbing the pipes under the kitchen sink. the house was built in 1946, it is a double sink going to a single wall drain whick terminates into a leaded galvanized 2 inch pipe into cast iron.

    from the bottom of the sink to the drain is 5 inches, the kitchen drains are 18.5 inches apart from center to center. i have tried all kinds of screw together pvc fittings to drain the sinks. no joy, they all leak. i replaced with glue together pvc, 1.5 inch, all is fine, except at teh tailpiece on the drain closest to the service drain into the wall. i screwed it down snugg and water then leaked from the tailpiece and the part that is screwed to the pvc glue joint. i thought okay, try another piece, no joy same thing. any suggestions would be appreciated at this point. is there a way to glue a tailpiece of pvc to the bottom of the sink and remedy this problem, or do i need to tear into the wall and replace the pipe to a level that all the drainage is farther downhill. thanks in advance. i have pictures if that would help.

    A picture would definitely help, since your description is confusing as to how you are trying to connect things together.

    hello,

    sorry for the confusion,

    what i have here is a sink side by side. tailpiece down on one side connects to a elbow that goes into a t piece connected to the other side tailpiece, which connects to a p trap, which is connected to the drain in the wall. i have removed the dishwasher piece that you see in the picture. consider it just too tail pieces connecting to pvc, via the screw together type connectors. trying to resize a photo to post.

    Apply pipe dope on the plastic washers tighten up and see if that works for you.

    You do have a problem, but it is that the pipe in the wall may be too high to make a proper installation. A Chrome plated brass "hi-line" end outlet waste might raise the horizontal pipe above the pipe in the wall, but it would be marginal. With your situation, I would install a "Y" at the wall and then pipe to two separate "P" traps, one for each sink.
