FLOWLOK Leak Detector The FLOWLOK 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. FLOWLOK Leak Detectors utilize a highly compressed safety disc that expands when it absorbs water. Once the safety disc has detected water it expands and trips the FLOWLOK safety lever to shut off the water entering the water filtration device. Safety discs are replaceable and are economical. FLOWLOK Safety Tray The FLOWLOK Safety Tray is a specially designed tray made to be used with most water filtration systems in the market today. You simply place it underneath you water filtration system and it helps contain any leaks which originate from the water filtration system. Its slightly oversized length helps capture any drips or leaks originating from connectors in the inlet and outlet of the filtration device. The adjustable holding bracket helps affix the FLOWLOK Safety Tray to most filter housings and aids to keep the tray firmly in its place. The FLOWLOK Safety Tray also has special designed placement slots so that the FLOWLOK Leak Detector can be securely mounted. FLOWLOK Safety Discs The highly compressed safety disc expands when it absorbs water, acticating the leak detector. Two pads are included with the system.
