I got to try a new way of emptying a large waterlogged water
pressure
tank.

There's no bladder, and I empty it just by opening the drain
and letting
the water glug out, which takes about 24 hours after it falls
to zero
net pressure.

Putting a twisty-tie end in the faucet sped that up to about 6
hours,
by shaping the glugs to more efficient large ones.

The new way, a drill pump sucking the water out, shortened it
to a
half hour. On the other hand, you had to be present to do it.

After it goes to glugs, pump as much water out as you can
(about a
minute of pumping); then undo the hose and let a huge suck of
air
pull into the tank; then repeat the drill pumping. That makes
it
drain in about half-gallon glugs, rather than dribbles.

Is there a fitting on this tank to pressurize it? If so, just
open the drain and blow air in. Then shut the drain off and
pressurize it. If it is appropriately pressurized, the pump will
cycle less.
