Air trapped in the hose causing inconsistent pressure?
Share
Air trapped in a pressure washer hose can cause inconsistent spray, pulsing, or surging. This guide will show you how to safely remove trapped air and restore smooth, even pressure.
Step 1: Turn Off the Pressure Washer
- Switch off your pressure washer (gas or electric).
- Disconnect the spray wand from the high-pressure hose for safety.
- Engage the trigger lock if your gun has one.
Step 2: Inspect All Connections
- Check hoses, quick connects, and fittings for leaks or loose connections.
- Tighten any loose fittings to ensure a proper seal.
- Replace any damaged O-rings or worn connectors.
Step 3: Bleed the Water System
- Reconnect the high-pressure hose to the pump.
- Ensure your water supply is turned on and flowing properly.
- Slowly squeeze the trigger on the spray gun to release air from the hose.
- Continue until a steady stream of water flows, free of sputtering or air pockets.
Step 4: Check for Obstructions
- Inspect the hose for kinks or sharp bends that may trap air.
- Straighten the hose completely and remove any blockages.
- Ensure the nozzle tip is clear of debris.
Step 5: Restart and Test
- Turn the pressure washer back on.
- Test the spray at a safe distance.
- Verify that pressure is consistent and smooth, without pulsing or surging.
Step 6: Optional: Prevent Future Air Traps
- Always turn on water supply before starting the pressure washer.
- Keep hoses straight and avoid sharp bends during operation.
- Periodically inspect connections and fittings for leaks.
Conclusion:
By following these steps, you can safely remove air from your hose and restore consistent pressure. Regular maintenance and proper setup prevent air from getting trapped and ensure a smooth cleaning experience.
✅ Pro Tip: If pulsing continues even after bleeding air, inspect your pump for worn valves or seals, which may also cause pressure inconsistencies.
