Which 8000 Series Valve Kit Do I Need?

Frequently Asked Questions

When should I replace the valve assembly?
Common signs of a worn valve are a pump that won't shut off or keeps cycling with the gun closed, pressure that won't hold steady, or trouble priming. Debris, scale and chemical wear on the valves are the usual causes.

How do I know if I have a By-Pass pump?
Check the model number on the pump label against the list above. If your model isn't listed, or the label says By-Pass, call us at 602-371-1993 and we'll find the right kit.

Any installation tips?
Clean any scale or debris off the housing surfaces before installing, and tighten the screws in a star pattern so the assembly seals evenly.
