How Tight to Turn Tank Drain Valve

Hi Bill. How tight should a tank drain valve be? Until the air stops flowing and maybe another quarter turn. Or, until the valve can't be tightened anymore.

Thanks Bill. That's what I thought, but I wanted to check.

Like any valve, in my opinion, you turn it to the point where whatever is behind the valve stops flowing.

Pointless to keep reefing on the valve to tighten it unnecessarily, and for valves with rubber seals, over tightening might damage the seal.

Assuming this is the tank drain valve we are talking about, this is the answer I use... "Until the air stops flowing "
