Problem
The pressure-depth ratio is too high.
Solution
Ensure air pressure is adequate for the pump depth (.50 PSI per foot of
depth). Having a high pressure-depth ratio will increase recovery time,
but decrease air consumption efficiency.
Continuous air coming out of vent
Solution

Inspect that when valve lever is in the up position there is a gap between the
valve and manifold, and ensure the vent valve is seated properly against the
O-ring.

O-rings are damaged in valve assembly. Inspect O-rings and check ball
inside manifold to ensure no cracks, tears, or damage. Replace as needed.
Springs in the valve assembly are not properly seated
Solution
Visually inspect the springs. Clean anything that could be caught in the
springs and make sure they are properly positioned.
