Frequently Asked Questions

It fits many Ultra, Ultra Max II, Pro210ES, and LineLazer units listed above. Because sub-variants differ (Standard, ProContractor, IronMan, Hi-Boy/Lo-Boy, year revisions), confirm via your model’s parts manual or serial-specific parts list before purchase.

The kit typically includes the valve assembly. Handles, bases, pins, or extra hardware are usually not included and should be reused from your sprayer unless otherwise specified in your manual or product listing.

If the old valve is leaking or stuck, replacement often restores priming. However, also check inlet strainers, pump packings, intake valves, and tip/inline filters for clogs or wear, and flush the system thoroughly.

Fully relieve pressure, lock the gun trigger, and disconnect power. Clean threads/mating surfaces; apply sealant only if your manual requires it. After installation, cycle the valve and inspect for leaks during a controlled flush.

Flush after each use with the recommended solvent, keep the return hose clean, and avoid dried-paint buildup on the valve knob and port. Periodic inspection prevents sticking and premature wear.
