The Leak Detector is an innovative device that installs right below your water filtration system in minutes. No special tools are required and it does not need electricity to operate. This device utilizes a highly compressed safety disc that expands when it absorbs water. Once the safety disc has detected water it expands and trips the safety lever to shut off the water entering the water filtration device. Safety discs are replaceable and are economical.
