Common Questions
- Will this kit fit my valve?
- The LFRK 709DCDA-CK2 4 fits the 4" size of Watts series 709DCDA / LF709DCDA. 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 second 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-CK2 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.
