Questions about this item

Do I already need a Powers tempering valve for this 390-580 rebuild kit to work?

Yes — the kit is designed to fit Powers tempering valves with manufacturer model numbers ES150-10 and ES150-11, so an existing valve is required.

Will the cylinder shuttle and O-ring in this kit install correctly on older Grainger items 25CC60 and 25CC64?

The kit replaces manufacturer number 390 580 and is listed for use with Grainger items 25CC60 and 25CC64, so the components are compatible with those units.

How can I confirm the poppet and springs are functioning after I rebuild the valve?

After reassembly, run water through the valve and verify steady, mixed-temperature flow without leaks or pressure surges at the outlet.
