  • Plastic boiler drain leaking on H.W. heater

    The threads are all boogered up to try to put a cap on it. Anyone have success on unsrewing one, and replacing. All the ones I have seen break.

    Even if it breaks you should be able to get it with an easy-out
    or pick it out in pieces or put the torch to it and melt it out.

      I break them and take a hacksaw blade and make a cut or two in the plastic threads and pop them out with a screwdriver.

      Must be a State WH.

          i've had decent luck with wiggling them just tiny bits back and forth until they loosen up a little.... then they don't always break


          I don't voluntarily leave those plastic valves in, ever.

            I never touch a plastic boiler drain unless I have a brass one in my hand to replace it with. Legend makes a nice full port drain.
