Leaks can cause tremendous amounts of damage. By having a simple leak detector on your RODI system is a great insurance policy against floods. The Flow-lok Leak Detector Kit has 1/4" push connect fittings that work with all of the BRS RODI systems. With a highly absorbent replaceable Leak Detector Pad when water is detected it will expand and trip the Flow-Lok Safety lever to stop the flow of water. The Flow-Lok Drip Tray mounts directly to the canisters of your RODI system so any leaks go directly into the tray where the Flow-Lok switch can be mounted for an instant shut off.
