Common Questions
- Will this kit fit my valve?
- The RK 757/RK 757DCDA-CK2 8 fits the 8" size of Watts series 757 / 757DCDA. 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 first check module, check module O-ring, and red silicone disc elastomer.
- Are these genuine Watts parts?
- Yes. This is the factory RK 757/RK 757DCDA-CK2 8 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 757 / 757DCDA in your size; a total repair (T) kit covers the relief valve and both checks.
