Common Questions
- Will this kit fit my valve?
- The RK 919-SV 1/4-1/2 fits 1/4", 3/8" and 1/2" sizes of Watts series 919. 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 relief valve seat 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 919-SV 1/4-1/2 kit built with genuine Watts OEM components. Aftermarket parts can void your assembly approval and are commonly rejected by inspectors at annual test time.
- My relief valve failed the test — is this the right kit?
- Yes. A relief valve that opens late, weeps continuously or fails to open is a relief valve fault, and this relief valve seat kit carries those parts for 919. If the checks also failed, a total repair kit rebuilds every subassembly at once.
