Abstract:

A fluid operated cylinder is suspended from a crane by a cable and has a piston rod connected by a cable to a cleaning unit for supporting the cleaning unit within the screened inlet portion of a water well casing extending into the ground. Air is supplied to the cylinder through a solenoid valve which is controlled in response to movement of the piston to produce reciprocation of the piston and corresponding movement of the cleaning unit within the well casing.
