Kit for Watts LF909 Backflow Preventers

This repair kit is designed for Watts Series LF909 backflow preventers in sizes from 1-1/4 to 2 inches. It provides the internal components needed to restore proper function to a valve that has worn or failed. The kit is intended for plumbing professionals and facility maintenance teams working on potable water systems.

Contents Support Long-Term Valve Reliability

The package includes a cover O-ring, disc assembly, lubricant, multiple O-rings, a piston, an RV diaphragm, and a seat O-ring. These parts address the common wear points that cause leakage or pressure loss during continuous service. Replacing them together helps the preventer maintain a tight seal over extended periods.

Verify Series and Size Before Ordering

Confirm that the installed unit is a Watts Series LF909 model within the 1-1/4 to 2 inch range before purchasing. The components are specific to that series and will not fit other backflow preventer designs. Check the valve body marking to ensure compatibility.
