    Pool Heater Drain Plug Bolt Sheared


    I was putting together the equipment in order to open the pool for the season. I was tightening up the heater drain plug bolt when it suddenly sheared in half. Does anyone have any clue how I get remove the sheared bolt? I'm hoping this won't be a major expense to repair.

    I have a Jandy Lite 2 heater.

    I know a few ways including drilling it out and retapping it, tapping it around with a cold chisel, applying heat (lots of eg OxyAcet), and my favorite, welding a tower of weld onto the stub and then a "T" bar to turn it.
    Whatever way you look at it it's usually a pig, I'd ask a mobile mechanic and let someone else swear at it.

    The brass plug? Stripped I've had happen, never sheared.
    There is a tool called an Easy Out. Since the brass plug is hollow, you don't need to drill. just a reverse threaded Easy Out on a T handle or drill the is a bit bigger than the hole. The reverse thread will bite into the soft brass and unthread the remaining piece of the plug.

    Like poolguy said, easyout. It works so well I've often been amazed, plus you already have the hole in it.

    you can get it at napa or uap. Take along the broken piece.
