Patent ID: 6945267

Claim:
A self-restarting pool cover siphon comprising: a housing adapted to be placed on top of a pool cover where water drainage is desired, the housing having a hollow interior and at least one opening through which water on the pool cover can drain into the hollow interior, the housing being weighted to remain on the pool cover, a tube having one end secured to said housing and in fluid communication with the hollow interior and an opposite open end through which water traveling through the tube drains, the tube adapted to be bent to form a loop therein, and the tube having an opening between the opposite ends thereof to be positioned at an upper position of the loop, and a differential pressure causing device removably connected to the opposite end of the tube for initially causing a differential pressure in the tube to cause the water in the housing to drain from said pool cover through the housing and said tube, and thereafter being removed from the opposite end of the tube, wherein additional water deposited on the pool cover will cause water remaining in the loop to pass by the opening in the loop to re-prime the siphon and cause drainage of water from the pool cover without further use and actuation of the differential pressure causing device.
