NORTH ANDOVER, Mass. — Integrated flood sensor technology is now standard on all large diameter (2-1/2 inch to 10 inch) Watts 909 backflow preventers. Flood sensors can be easily activated with add-on cellular or BMS kits.
Sensors are designed to detect discharge from the RPZ backflow’s relief valve, so action can be taken to prevent flooding.
