Adam!
It's not a first resort!  Not a second resort!  Not the third either.  It's
the LAST resort.

If you don't want to spend about a hundred dollars on a valve, then don't.
All we're saying it you'll never get your hatch opened if you need to as a
LAST resort even if you have divers down there to rescue you.

My hatch is 24 inches in diameter.  That's about 450 square inches.  At two
feet below the surface, it would take about 450 pounds of force to open it
if I had to ,without equalizing the pressure.

A valve is cheep,
Dan H.
