Repair Kit for Watts Series 909 Backflow Preventers

This repair kit is designed for maintenance of Watts Series 909 backflow preventers ranging from 3/4 to 1 inch. It contains essential replacement components including a cover O-ring, disc assembly, lubricant, seat, seat O-ring, and spring. The kit suits plumbers and facility managers performing scheduled upkeep or emergency repairs on these specific valves.

Restores Sealing Performance on Worn Series 909

Use this kit when the existing check mechanism shows wear, leakage, or failed test results on a Series 909 device. It replaces the internal soft goods and spring to restore proper sealing function without replacing the entire valve body. The jump is worth it when the valve body remains sound but internal components have degraded.

Maintains Reliability During Continuous System

Under sustained supply pressure the replaced O-rings and spring maintain consistent sealing force over long periods. The included lubricant assists smooth disc movement during repeated flow cycles, helping the assembly resist creep and degradation better than aged original parts.
