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?
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

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