Installation & Care
- Depressurize sprayer and isolate fluid supply before disassembly.

Frequently Asked Questions
Check your machine’s parts list for the check/outlet valve in the fluid section. If it specifies 101701, this is the correct ball. If unsure, share your model and pump/fluid-section number with our team for verification.
If the seat shows pits, grooves, or a dull sealing ring, replace it along with the ball. A worn seat can prevent proper sealing and shorten the life of a new ball.
Difficult priming, loss of pressure, excessive pulsation, or fluid leaking back through the check valve often point to a worn ball or seat. Inspect both components and replace as needed.
