drain valve won't reseal after opening

by Carl James

Drained tank like I was supposed to, reinstalled nut. Now air flows out of it freely.

Carl, does the air flow when you rotate the nut both ways? By this, I mean, turn the nut all the way to stop one way. If air continues to flow, turn the nut all the way to stop the other way.

If air continues to flow after turning the nut all the way to a full stop in both directions, and by the way, mine does not "screw off" like it sounds like yours did, then it's likely time to replace the valve.

Cheers,
