Liner Pressure ( Hydrostatic) Relief Valve

Relieves the air and water that can build up under pond liners from the water table. This is a spring loaded device that opens when the pressure is built up underneath. Then when the pressure is relived the valve will close back again.

A minimum pressure of 1.25lbs is recommended to get enough pressure for the valve to open.

The hydrostatic relief valve threads into a 1-1/2" or 2" bulkhead fitting.
