What to do if Magnum X5 Paint Sprayer pump will not prime?
- KKristin KerrAug 21, 2025
If the Magnum Paint Sprayer pump won't prime, check these potential causes and solutions: * Ensure the Prime/Spray valve is set to PRIME, not SPRAY. * Clean any debris from the inlet screen. * Reposition the suction tube so it's immersed in the paint. * Press the pump priming button twice to dislodge a stuck inlet valve check ball. * Unscrew the outlet valve and clean the assembly if the outlet valve check ball is stuck. * Tighten the suction tube connection and inspect for cracks or vacuum leaks. * Clean or replace the drain tube if the Prime/Spray valve is clogged. If the drain valve remains clogged, return the sprayer to an authorized service center.
