Abstract
A vacuum relief valve releases vacuum force at a pool suction cover when the suction cover is obstructed. A valve plunger rests against a valve seat within a valve body under normal pool operating conditions. A biasing member maintains the valve plunger against the valve seat. The biasing member compresses and moves the valve plunger to a position away from the valve seat when the suction cover is obstructed. Once the obstruction is removed, the valve plunger is automatically returned to its resting position against the valve seat. The valve body is attached to fluid conduit that carries a source of air to the pump when the valve plunger is moved away from the valve seat.
