Common Questions
- Will this kit fit my valve?
- The LFRK 909M1-RT 8 fits the 8" size of Watts series LF909M1 / 909M1, design revision M1 only. Watts changed internal parts between revisions, so check the model stamped on your valve body or cover before ordering.
- What's included in this kit?
- This is a total rubber parts 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 LFRK 909M1-RT 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?
- For a relief valve fault on LF909M1 / 909M1, order the RV kit for rubber parts only or the VT kit to replace the complete relief valve assembly. This total rubber parts kit covers a different part of the assembly.
