Air trapped in the hose causing inconsistent pressure?

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

  1. Switch off your pressure washer (gas or electric).
  2. Disconnect the spray wand from the high-pressure hose for safety.
  3. Engage the trigger lock if your gun has one.

Step 2: Inspect All Connections

  1. Check hoses, quick connects, and fittings for leaks or loose connections.
  2. Tighten any loose fittings to ensure a proper seal.
  3. Replace any damaged O-rings or worn connectors.

Step 3: Bleed the Water System

  1. Reconnect the high-pressure hose to the pump.
  2. Ensure your water supply is turned on and flowing properly.
  3. Slowly squeeze the trigger on the spray gun to release air from the hose.
  4. Continue until a steady stream of water flows, free of sputtering or air pockets.

Step 4: Check for Obstructions

  1. Inspect the hose for kinks or sharp bends that may trap air.
  2. Straighten the hose completely and remove any blockages.
  3. Ensure the nozzle tip is clear of debris.

Step 5: Restart and Test

  1. Turn the pressure washer back on.
  2. Test the spray at a safe distance.
  3. Verify that pressure is consistent and smooth, without pulsing or surging.

Step 6: Optional: Prevent Future Air Traps

  1. Always turn on water supply before starting the pressure washer.
  2. Keep hoses straight and avoid sharp bends during operation.
  3. 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.
