Common Questions
- Will this kit fit my valve?
- The RK 957/957RPDA-CK1 10 fits the 10" size of Watts series 957 / 957RPDA. 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 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 957/957RPDA-CK1 10 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 957 / 957RPDA in your size; a total repair (T) kit covers the relief valve and both checks.
