Common Questions
- Will this kit fit my valve?
- The RK 757/RK 757DCDA-RC4 2 1/2-4 fits 2 1/2", 3" and 4" sizes 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 check rubber parts kit (first or second). Kit consists of: a check module O-ring, red silicone disc elastomer and a E-clip.
- Are these genuine Watts parts?
- Yes. This is the factory RK 757/RK 757DCDA-RC4 2 1/2-4 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 757 / 757DCDA in your size; a total repair (T) kit covers the relief valve and both checks.
