What's included in this kit?

This is a first check kit. Kit consists of: a disc assembly, spring and a cover O-ring.

Are these genuine Watts parts?

Yes. This is the factory LFRK 709DCDA-CK1 4 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 709DCDA / LF709DCDA in your size; a total repair (T) kit covers the relief valve and both checks.
