    Sink copper drain pipe leak
    Hi,under my kitchen sink the drain goes through the normal trap then into the wall where it is connected to a 1.5 inch copper pipe . This pipe runs on a slant to the main drain in the basement.the first six inches of the copper pipe runs level then through a elbow on the slant to the main drain.the house was built in 1962. On the bottom of the level pipe a leak developed which was not detected until it got bad enough that it was draining into an enclosed section under the sink.i broke through the wall under the sink and located a half inch by one quarter inch hole on the bottom of the pipe.i wrapped a piece of cork around the pipe and over that a piece of vinal tile .i secured this with metal clamps.
    I hope ,because the six inch length was level ,and some drainage always laid in this section,is the reason for etching of the copper.however the long coppoer pipe ,enclosed in the wall , that is on a slant will not have a problem.if it does do you have a solution without tearing out the wall.
    Such as a flexable pipe that would fit in side the copper pipe.
    I don't have a problem now but i like toplan ahead.

    You have already broke through part of the wall. You will be time and money ahead if you replace the copper with pvc plastic. Since it is glue together, you won't have to solder and that should make it easier to do without making too big a mess with the size of access that you need to make to replace it.

    Hi Jerry:

    The copper pipe has gone bad as you know. It will only continue to be an issue over time so you would do best to replace back to a spot where the pipe is in good shape.

    Cut the copper pipe out using a sawzall with bimetal blade and replace with PVC pipe and fittings.

    Use an 1.5" copper to PVC shielded clamp (see image) to make the transition to PVC. Purchase some PVC primer, PVC cement and appropriate fittings and pipe. Should be a pretty quick job, overall.

    Let us know if you'd like to discuss more... OK?
