## Overview

The WaterWatcher Leak Detector is a compact, easy-to-install device that senses minimal water leaks (as low as 0.2 inches), instantly shuts off connected appliances up to 14 Amps, and sounds a loud 85 dB alarm to prevent flooding and water damage. Compatible with a wide range of household and industrial appliances, it offers a 5-year warranty and dedicated customer support, making it an essential safeguard for any modern home or workspace.

## Description

The WaterWatcher is designed to detect very small amounts of water on the floor and switch off the appliance that is causing the leak. It very easy to install. Just place the sensor puck on the floor where the risk of leakage is greatest, plug the control module into the 120 VAC outlet, and plug the appliance into the control module. Under normal conditions, the output of the WaterWatcher is on, and power is supplied to the appliance. But as soon as water is detected, the output switches off and an alarm is sounded. The switch stays in this state until its reset by unplugging it and plugging it back in. For use with 120 VAC 14 Amp max appliances. Comes with 12' sensor cable. The WaterWatcher is great for dehumidifiers, hydroponics, aquariums, dishwashers, etc.

Review: Compact sensor, not only alerts with 85 db alarm but also shuts off my dehumifier. I use a dehumidifer in the attic above my clothes closet (yes you can guess my problem). The dehumidifer did its duty, overflowed and ran down from the unfinished attic into my closet. 7 suits, numerous shirts, some Sheetrock damaged and corner tape required fixing. Found this alarm/shut off switch on desertcart. Am working right now to test a catch basin that houses the dehumidifier so if an overflow occurs it sonically notifies us while turning off the dehumidifier. So far all the “mock-ups” have worked, water in the catch basin sets off the alarm as well as turns off the dehumidifer long before there is enough water to cause damage. The alarm sets off at 0.2 inches of water in a 5 inch deep catch basin. Plenty of leeway. Easy to install, connects to a single electric receptical. Pretty loud alarm, don’t know if I really need that because of the automatic shutoff.
Review: This device works just as it was intendent. Like the added reset/mute button. I have installed on a 3/4 HP water pump. It gives me peace of mind knowing my basement won't flood if a pipe bursts or a connection fails.
