Abstract:
1. A water well pump comprising: a first member having an exterior elongated shell surrounding a tube member and an intake tube; a one way standing valve positioned above said intake tube within said first member for receiving well water, said one- way standing valve having an elastic ball supported by a first support means and maintained within said one-way standing valve by a blocking means, wherein said blocking means comprises a damper ring to reduce water hammering when said water well pump is in operation; a piston stop within said first member positioned above said one-way standing valve and within said tube member to stop a piston when said water well pump is in operation; a second member having said piston surrounding a release tube and a joining tube, said piston positioned at the bottom of said second member and movable axially within said tube member, said piston having an upper end adjacent said release tube and a lower end in axial communication with said piston stop when said water well pump is in operation; a one way traveling valve positioned within said piston, said one way traveling valve having a ball supported by a second support means and maintained within said one-way traveling valve by an angular blocking means, wherein said angular blocking means comprises an angular ball stop designed to block said ball and roll it to the side of said one way traveling valve; a plug positioned within said joining tube to block water from exiting said joining tube; a plurality of release ports positioned on the exterior of said release tube to permit water to exit said release tube into water lines; and a first sealing means used to fit said tube member within said shell comprising slits cut in the exterior of said tube member which compress under hydraulic force.
