ABSTRACT:
A leak detection apparatus is shown for monitoring leakage from household water systems. Upon detection of a leak, the water supply valve is automatically shut off. A pair of spaced apart wires are imbedded in an insulating tape with liquid cell sensor elements formed at spaced intervals about uninsulated sections of the wires. The tape is placed about the pipe to be monitored so as to collect the leaking water within the liquid cell sensor elements to electrically connect the conductors within a cell. Electronic circuitry actuates a servo to turn off a supply valve and/or sound an alarm. The water collecting elements eliminate unintended alarms due to condensation.
