First Check Valve Repair Kit

This kit provides the internal components required to service a Watts Series 909 first check valve in the four-inch size. It is intended for plumbing professionals and maintenance crews who need to restore proper backflow prevention on existing assemblies.

Includes Cover O-Ring Disc Assembly Lubricant

The package supplies every wear item needed for a complete rebuild so the valve body can remain in line. Replacing these parts together eliminates the need to source individual seals or springs and returns the assembly to reliable operation without full replacement.

Restores Sealing and Spring Function on Four-Inch

The components handle normal debris and pressure cycles found in commercial backflow installations. They do not address damage to the valve body itself or seats that are pitted beyond what the new disc and O-ring can seal.
