Common Questions

Will this kit fit my valve?

The RK 909-RC1 2 1/2-3 fits 2 1/2" and 3" sizes of Watts series 909 / LF909. Kits are size- and series-specific, so match the model stamped on your valve body or cover before ordering.

What's included in this kit?

This is a first check rubber parts kit — it carries the factory parts for that subassembly only, not a whole-valve rebuild. See the Watts spec sheet for the exact part breakdown.

Are these genuine Watts parts?

Yes. This is the factory RK 909-RC1 2 1/2-3 kit built with genuine Watts OEM components. Aftermarket parts can void your assembly approval and are commonly rejected by inspectors at annual test time.

Which kit do I need if my relief valve failed the test?

Not this one — this kit services the check valve. A failed relief valve needs the RV (rubber parts) or VT (total relief valve) kit for 909 / LF909 in your size; a total repair (T) kit covers the relief valve and both checks.
