Questions about this item

How do I install the Watts 009 Total Relief Kit and what step is commonly missed?

Shut off water, remove the old relief valve, then fit the new cover O-ring, RV spring, seat, seat O-ring, stem and diaphragm assembly, and stem O-ring; the step often missed is seating the cover O-ring fully before tightening the bonnet.

Which parts of the Watts 009 Total Relief Kit will need replacement later?

The rubber components — cover O-ring, seat O-ring, stem O-ring, and diaphragm — wear with pressure cycles and mineral build-up; the RV spring and metal seat typically last longer but should be inspected during each service.

What limit appears first on the Watts 009 Total Relief Kit under sustained use?

Continuous high-pressure cycling and heat accelerate diaphragm fatigue and O-ring hardening, causing the relief valve to weep or fail to reseat before the metal parts show wear.
