A suction relief apparatus for relieving suction at a suction connection of a swimming pool or spa having a main valve member movable from an open to a closed position to relieve suction at the suction connection in the event of a blockage of the suction connection in the pool. The main valve remains closed until a reset valve is opened, at which time a spring returns the main valve to the open condition, enabling suction to resume at the suction connection of the pool. A switch responsive to increased suction indicative of an obstruction may be utilized to deactivate a suction pump motor. In an alternative embodiment, a frangible member may replace the main valve and reset valves to open a connection to ambient air atmosphere in the event of increased suction in the suction line resulting from an obstruction at the suction connection in the pool.
