ABSTRACT:
The present invention contains a one-way standing valve holder and a one-way traveling valve holder. Contained within a shell of the standing valve holder are a nipple at the upper end and an intake tube at the lower end. A piston rod extends down from the earth's surface to the traveling valve holder. At the lower end of the release tube is a piston. The piston end of the traveling valve holder is inserted into the nipple end of standing valve holder aligning the piston with piston stop. An elastic ball within the shell creates a one-way standing valve, and a hard ball within the piston creates a one-way traveling valve. Surface equipment connected to traveling valve holder is used to reciprocate the pump up and down opening and closing the one-way valves at alternating intervals. Water fills into the riser pipe and additional pumping allows collection of water.
