Frequently Asked Questions

Erratic pressure control, inconsistent spray output or unusual valve noise may indicate spring fatigue.

Use only the OEM spring unless the manual specifies a different rate; changing spring rate can affect performance and warranty.

Inspect during each major service; replace if signs of fatigue, corrosion or inconsistent pressure control are found.
