Greetings,

I have a water heater drain that drips even when turned off HARD. I
would like to purchase a cap to screw over the drain. What type of
threads does it have (garden hose threads?) and what is the type of
cap I need called so that I can order it online? Can anyone suggest a
good place to order such things online? Is there a different / better
solution that will be quicker and cheaper?

Thanks,
William

Go to your local hardware store and get a cap that fits a 5\8" garden hose.
I've done it more than once. This is probably a good argument for NOT
periodically draining water heaters. I've drained some waters heaters I've
owned and not others and the only consistent results I've gotten were leaky
valves.

If it HAD been drained regularly, then the valve would not have gotten crap
in it and began leaking.

I'm not sure I believe regular draining prevents valve leaks, either. I
just replaced the leaking (plastic) valve in my 6 yo gas water heater. I
have drained only occasionally, and the water always came out clear. The
old valve had no "crap", and was totally clean. I believe the washer had
deteriorated and probably could be replaced to repair the valve.

I bought a quality hose bib (the ball valve kind) to replace the old
valve. I thought I would have to totally drain the heater, but I didn't.
I closed the inlet valve and put a bucket under the drain valve. I turned
to pilot setting and waited a few hours for it to cool somewhat. I
unscrewed the valve and although some water dripped into the bucket, it
didn't all come out. I worked quickly to screw in the new valve with
teflon tape. I doubt if over a gallon came out altogether. I suspect a
vacuum forms that keeps the water from draining, as long as no taps are
open.

I was too dumb to think of the cap trick, which would be less work.
Probably cheaper too.
