WARNING WARNING!!!
Most drain valves are junk, espically the plastic ones, once opened it
may NEVER close:( You can buy a cap that fits with a washer to close
the drain when your done. be prepared to replaace the valve, like start
early AM of day off not end of day:(
Turn burner off leave pilot on.
messing with the T&P valve may cause it to leak.
your better off opening valves anywhere above the height of the tank to
assist draining by allowing airr to enter
