Why Graco Paint Sprayer pump cycles but does not build pressure?
- MmichaelreevesSep 2, 2025
If your Graco Paint Sprayer pump cycles but doesn't build up pressure, try the following: * Prime the pump. * Check the inlet screen for clogs and ensure the suction tube is immersed in the fluid. Clean any debris off the inlet screen. * Refill the paint pail and re-prime the sprayer if the paint pail is empty. * Inspect the suction tube for leaks. Tighten the connection and look for cracks or vacuum leaks. Replace the tube if damaged.
