PIPE FREEZE-PREVENTION SYSTEM

摘要

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.

主权项

1. Apparatus for reducing a risk of water pipes freezing, said apparatus comprising:
a) a control valve assembly including a solenoid-operated valve having both a valve and a solenoid, said control valve adapted for attachment in a waterline; b) an electrical control circuit for energizing said solenoid to cycle said control valve assembly on and off up to 48 times per day, said control circuit including
i) a first electrical switch to activate said solenoid-operated valve;ii) at least one cycle timer [optionally] associated with said solenoid for operating said solenoid to open said valve allowing water to flow through the waterline for a set period of time on the order of one minute preventing ice buildup within the waterline;iii) a thermostat [optionally] connectable in said control circuit to activate said control valve when an atmospheric temperature drops below a set level.
