Abstract

See full text

A system for reducing the risk of waterlines freezing provides a solenoid controlled valve which may be cycled twice an hour for a minute (or longer if desired) to avoid ice buildup in the lines. The control circuit allows the homeowner flexibility in determining whether to allow the cycle timers (preferably 3 inexpensive timers) to control the solenoid valve's cycling directly or to permit a thermostat to intervene, cycling only when the set point of the thermostat is reached.
