Abstract: A small lightweight battery operated remote switched bilge pump is provided weighing less than one pound for installing in a small watercraft, including a kayak, canoe, sailboat, row boat, dingy, featuring a bilge pump having a low voltage inline pump, a housing having a compartment with an integrated strainer base to receive the low voltage inline pump, and having a watertight compartment to receive lightweight batteries to power the bilge pump for about 1.5 hours, and a switch assembly to selectively operate on/off functionality of the bilge pump remotely; and a Velcro® arrangement to couple the bilge pump to a surface of the small watercraft to allow easy installation of the bilge pump in about 15 seconds to perform bilge pump functionality without drilling or making holes in the small watercraft, and to allow easy removal of the bilge pump for cleaning and battery replacement.

Abstract: A fluid release valve includes valve housing (VH) coupled between a pump and an outlet pipe, VH chamber providing fluid from its inlet and outlet when the pump starts, and fluid release orifice (FRO) draining outlet pipe fluid flowing back into the VH when the pump stops; and check valve (CV) combination having a CV shuttle that moves towards/away from the inlet/outlet and an internal shuttle chamber (ISC), and having a CV that moves towards/away from the inlet/outlet within the ISC. The CV combination responds to a pumped fluid pressure when the pump's pumping and stops the fluid from flowing from the inlet around the CV shuttle and out the FRO. The CV combination responds to a fluid differential pressure (FDP) when the pump stops and allows the outlet pipe fluid to drain out the FRO until the FDP reaches an equilibrium.

Abstract: A utility pump is provided featuring a housing and battery configuration, where the housing is configured with a series configuration of integral pumps, and also configured with a battery receiving portion having electrical terminals for receiving power for providing to the series configuration of the integral pumps, and where the battery has a protruding portion with corresponding electrical terminals configured to contact the electrical terminals to provide power to the series configuration of the integral pumps when the protruding portion of the battery is inserted into the battery receiving portion of the housing and rotated in one direction to an “ON” position, and also configured not to contact the electrical terminals when the battery is not rotated to the “ON” position.
