Abstract: A water system includes a reciprocating pump operated by pedal and motor delivered solar power, including one-way engagement clutch elements preventing hazardous pedal movement and potential motor damage. The pumpstand includes a housing in which a foot pedal and a drive shaft rotate. An eccentric pin, rotating with the drive shaft, moves a connecting rod, which in turn causes a pushrod to oscillate vertically. The pushrod extends into a pressure-tight chamber formed above the rising main (well pipe). A pumprod connected to the pushrod extends to move a conventional plunger through vertical oscillations. A flywheel is attached to the drive shaft, and a counterweight is mounted on the flywheel diametrically opposite the eccentric pin. The radial distance from the drive shaft to the counterweight can be adjusted. A discharge pipe extends from the pressure-tight chamber to an elevated or pressurized storage tank.

A distribution pipe from the storage tank feeds water to a number of distribution points, such as faucets in houses.
