Questions about this item

Will the Watts 909 repair kit components withstand continuous high-temperature discharge cycles?

The kit includes a cover O-ring, disc assembly, lubricant, seat, seat O-ring and spring designed for Watts Series 909 relief valves; these parts are engineered to handle the thermal and pressure loads the valve encounters during normal operation.

Which existing valve body must I already have for this kit to fit?

This repair kit is made for Watts Series 909 relief valves in the 3/4 to 1 in size range; you need the matching Series 909 valve body installed in your system.

Can I use the seat and spring from this kit in an older Watts 909 valve that has been in service for years?

Yes, the seat, seat O-ring and spring are direct replacements for the original components in Watts Series 909 valves, so they will work in an older unit of the same series and size.
