Frequently Asked Questions
Why does my pump need a new valve cartridge?
Valve balls and seats wear with use — especially with abrasive or crystallizing chemicals. Worn valves cause output drop and poor accuracy.
Can I replace just the ball instead of the full cartridge?
Yes, balls are available separately. But a full cartridge is more reliable because the seat and spring wear together.
