    Just registered with the forum yesterday.
    Thanks for having me. I searched for an
    answer before asking a question, but couldn’t
    find anything.

    I have an 8 year old American Water Heater.
    It’s a 40 gallon natural gas with a power vent.

    It has been neglected and I wonder if there is
    any hope for it? Not sure if this matters, but
    it has always had filtered water down to 20
    microns (seems like can’t hurt?).

    It has never had the anode replaced, or even

    If there is hope, I’d like to start by draining it,
    but I’m concerned that if I mess with the drain,
    it may break, or get stuck “on”, or anything
    else bad. I attached a pic of the drain. It’s
    nylon, plastic or something like that (I know
    now I should have a ball valve).

    My question is:
    While I know there are no guarantees with
    anything, what are my chances that the drain
    valve will work like it’s supposed to?

    Chances being pretty good, 50/50, or just
    thinking about touching it is playing with

    If the drain will work, I’ll have a look at the
    anode, but I think the chances there’s anything
    there are miniscule to none. Is there a chance?

    Thanks for your help.

    Hello, The present drain will work for relieving pressure and for draining the tank. That’s all you need for anode checking/replacement. Once the tank is drained, then it’s time to try replacing it with a proper valve. Even if it snaps in two when trying to unscrew it, no problem. Just take a hammer and large screwdriver to remove the remaining plastic ring without doing damage to the steel tank threads. Most important is to have a look at the anode!
    Yours, Larry
