Abstract:
An automatic shutoff valve installed at the opening of a skimmer outlet pipe that communicates with a pool circulating pump inlet, said valve comprising:(a) a float disposed within a retainer and above a valve body attached to said retainer, said valve body containing a valve seat, said float being sized to sealably seat on said valve seat, and is free to move within the retainer, (b) said float is normally in an open position removed from said valve seat; (c) said float is a resilient material of positive buoyancy in water; (d) said float comprising a ping-pong ball; (e) the resilient float creating a water and airtight seal with the valve seat, thereby eliminating the need for an â€œoâ€  ring or other form of resilient seat material; (f) the valve being design to be installed and removed from a position above the outlet skimmer pipe without the need for tools; (g) the valve communicates with the pool's circulation pump inlet when water level in the skimmer outlet pipe is restored, thereby releasing the float from the valve seat without the need for lifting device; (h) the valve body being substantially cylindrical; (i) means for securing said shutoff valve to a skimmer outlet pipe.
