For single water appliances like water heaters, protect with this single appliance LeakStop PLUS WaterCop system. Alerts to water leaks and shuts off water valve automatically when either or both of the two moisture sensor probes get wet. Also has a security output. Install the water valve, install the controller and place the two moisture sensor probes where water is likely to accumulate under or near the appliance.

Use conduit at the bottom to hard wire to third party devices. Be notified via a light, buzzer, auto dialer device or security/automation system. Maintenance persons or home owners then receive immediate notification about the closed valve.

Please note this unit cannot use additional WaterCop sensors.

NOTE: Lead-free valves are approved for sale in all U.S. States, and comply with California AB1953 and Vermont S.152 laws.
