    Tackled project today. Took old fitting off and sweated new one on. Everything went great just hard to get to behind hot water tank. Feel better nothing to worry about now. Again thanks for all the suggestions.

    If this is all accessable and you have a torch then you can most certainly sweat the joint apart providing it is dry. You can also clean all the fittings up and resolder it or replace the fitting. very easy just pay attention to your heat control. If the flame turns green then BACK OFF. Solder is drawn into the joint by capillary action.

    And once again DEBBIE, please stop it. You are dangerous.

Solder it up and you're all done.


    Another method that works, but I don't recommend it if you can do the above repair, is to use a bandaid. You cut a union fitting in half along it's length and it's width to come up with a arched piece of copper. Shine up the patch and the repair area and solder it in place.
    This "arched piece of copper" idea is intriguing, BUT how do you hold it in place while attempting to heat it and apply solder ??

    richard,

    A little piece of light gauge wire cinched around the thing should do the trick.

    A big clothespin will work also and doesn't act as a heat sink.

    Another method would be to pre-tin the patch and the pipe, then hold the patch in place with pliers and apply the heat.
