Frequently Asked Questions

Check your sprayer’s model and series label (e.g., X5/X7 with a specific series letter). If your unit is listed under the Compatible Machines section above, this kit is typically correct. When in doubt, share your model/series and we’ll verify before you order.

Common signs include pulsation at the gun, pressure instability, rough or uneven spray pattern, or difficulty maintaining prime/pressure after the pump stops cycling.

Yes—this kit includes the outlet valve assembly and associated small parts required for the service. Exact contents may vary by kit revision; if you need a contents breakdown, let us know your sprayer’s model/series.

Depressurize and unplug the sprayer, follow the service procedure in your model’s manual, keep the valve seat and bore clean, torque to spec, and test with water before paint. Replace worn inlet components at the same time if needed for a complete refresh.

The outlet valve controls flow from the pump to the hose (discharge side), while the inlet valve controls flow from the suction tube into the pump. Each has its own service kit; using the correct kit for each side ensures proper one-way flow and stable pressure.
