    Reckers:

    You can always try to use an epoxy putty to fill the pinholes (see pic.)... it comes in a tube and works pretty good at patching small holes/tears in lead pipes.

    Here, want to rough the surface of the lead to be repaired using sandcloth or a cleaning brush (see pic.), apply the putty in thin layer, then work it around the edges with a wet finger tip to BLEND the edges of epoxy putty to the lead pipe. This works most of the time... temporary, but works well (I have some patches that are 5-7 years old and still going strong.

    Be careful not to push to hard on the lead pipe when cleaning/prepping... could puncture lead, and that could be awful!

    Anyway, if can't replace the lead pipe, try the epoxy putty. Let us know how it goes.

    Good luck... Mark
