Corrosion in the pump or fittings?

Corrosion in your pressure washer pump or fittings can reduce efficiency, cause leaks, and shorten the life of your equipment. Regular inspection and proper maintenance can prevent serious damage. Follow these steps to identify and fix corrosion issues.

Step 1: Turn Off and Disconnect

  1. Turn off your pressure washer and disconnect it from the power source or engine.
  2. Release pressure from the system by squeezing the trigger on the spray gun.
  3. Disconnect hoses, wands, and fittings to access the pump.

Step 2: Inspect for Corrosion

  1. Examine the pump body, fittings, and connectors for rust, discoloration, or pitting.
  2. Check threaded connections for buildup or damage.
  3. Identify any areas where corrosion may have compromised seals or O-rings.

Step 3: Clean Corroded Areas

  1. Use a wire brush or soft abrasive pad to remove surface rust from metal fittings.
  2. For tougher corrosion, soak small metal parts in a vinegar or rust remover solution for several hours.
  3. Rinse thoroughly with clean water and dry completely before reassembly.

Step 4: Replace Damaged Components

  1. Replace any fittings, O-rings, or connectors that are pitted, cracked, or too corroded to clean.
  2. Check the pump seals—corrosion can damage them and cause leaks. Replace as needed.

Step 5: Prevent Future Corrosion

  1. Always flush the pump with clean water after each use.
  2. For long-term storage, use a pump saver or antifreeze solution to protect metal parts.
  3. Store your pressure washer in a dry, covered area to minimize exposure to moisture.

Step 6: Reassemble and Test

  1. Reconnect hoses, fittings, and wands securely.
  2. Turn the pressure washer on and test for leaks or pressure drops.
  3. Ensure the spray is smooth and even.

Conclusion:
Addressing corrosion early prevents leaks, pressure loss, and pump failure. Regular cleaning, proper storage, and preventive maintenance extend the life of your pressure washer equipment.

✅ Pro Tip: Inspect your pump and fittings monthly if you use your washer frequently, and always flush and dry after chemical use to prevent corrosion.
