THE SENTRY *Under Counter Water Sensor/Alarm & Shut-off Valve*
A handy device for any under-counter water system, the Sentry is quickly and easily installed into your under counter Water-Revolution system. This battery-powered control unit shuts down water flow to your equipment when a leak is detected. The Sentry blocks the incoming supply water flow from your plumbing and generates an acoustic signal and blinks a blue light continuously to notify you of the detected problem.
Annual replacement of 9V battery is recommended.
