    Default 1/2 coper out of anode port

    hi,

    i have a 1/2 coper line coming out of my hwt and going into the ceiling im unable to trace where the line goes.

    just wondering generally why you would have a line into the anode port? there is 3/4" and both the hot and cold supplying the house and tied into the well pump

    thanks

    Does it get as hot as the outlet pipe does, suggesting that it supplies hot water to somewhere? Do you get instant hot water at any faucet? Do you have any in-floor radiant heat?

    It might be a return line on a recirc pump.

    The anode port usually has either an anode rod or a plug in it. The only explanation for what you describe is that someone needed a place to connect a hot water pipe and that was the easiest spot. WHERE it goes, howver, we cannot even begin to tell you that.

    Removing the (sacraficial) anode from a WH could significantly shorten its service life. Depends some on your water quality. The anode gets preferentially eaten away rather than the steel lining of the tank. Remove it, and you are totally at the mercy of the quality of the liner. WIth it, even with a small defect in the liner, the anode gets eaten up rather than the tank. If you keep a good anode in the tank, it can last a very long time.

    there is no radiant heat in the house and no instant hot water, Im gonna hook up a new tank and just hook it up the same way the old one was hooked up and hope for the best ;-)

    Jim is right, and removing the anode could void warranty on your new tank as well as shorten its life. Why not just cut a valve into the line and turn it off, then go around and see where there is no more hot water. Then you will be able to plumb it up right when you put in the new tank.

    I do not believe the anode threads are pipe size. Finer. You might have a remote PRV somewhere?
