    Default How to stop bathroom sink leak

    Hello,

    I just installed a new sink and vanity, I'm having one annoying issue: the long (approx 8") portion at the end of the P-trap which goes into the wall is leaking where it meets the metal drain pipe coming from the wall (small drip from bottom where they meet). There are no fittings at this part just a straight 6" of PVC which fits snugly into the metal pipe coming from the wall, so I'm confused on how to stop this leak. Is there something that I can wrap around the PVC? It is super tight as is now so I am not sure what would work....

    Anyway any help would be appreciated, thanks

    Post a pic of what you have done.
    I'm guessing you need a trap adapter.
    Them come in plastic and metal.

    If the pipe is 1-1/2 galvanized you need a slip joint washer and lock nut.

    That is about the best way to guarantee that the end of the galvanized pipe will "rust away". Use a brass female trap adapter and prevent it from happening.

    How would a brass female adapter be any better than a brass brass or plastic slip nut?
