Abstract
A well pump system having a motor-driven pump and a pressure tank for delivering water from a source to a utilization point. A sensing device detects a parameter correlated to the rate of flow into and out of the pressure tank. The parameter is utilized to regulate flow into the tank so as to establish at least approximate equality between flow into and out of the tank.
