Common Questions

Will this kit fit my valve?

The RK 919-T 1 fits the 1" size 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 total repair 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-T 1 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 919, order the RV kit for rubber parts only or the VT kit to replace the complete relief valve assembly. This total repair kit covers a different part of the assembly.
