Why is air always coming out of the Kremlin-Rexson Water Pump spray gun when priming?
- JJeffrey GeorgeAug 4, 2025
If air is constantly coming out of the spray gun during priming, or if air (or material) fails to come out at all, it could be due to air intake at the fitting or suction rod. Ensure the spray gun is fully opened to allow air to evacuate. Inspect the pump valves. If a valve is stuck due to dried paint, try dislodging it by blowing air pressure directly through the suction fitting without disassembling the pump.
