One task you don't want to skip is priming your pressure washer pump.

Why Should You Prime a Pressure Washer Pump?

Priming your pressure washer pump is all about ensuring it's ready to function properly by removing any air trapped inside the pump. Without priming, your pressure washer may struggle to draw water or could operate inefficiently, leading to poor cleaning results and potential long-term damage.

Failing to prime the pump means air pockets can remain inside, and when this happens, the pump won't be able to build up the pressure needed for effective cleaning. It's a bit like trying to drink through a straw that has a hole in it — air gets in the way and ruins the flow! In summary, priming your pressure washer:

  • Prevents damage to your pressure washer
  • Prolongs pressure washer pump life
  • Ensures optimal performance

Signs Your Pressure Washer Needs Priming

  • Loss of pressure: A significant drop in water pressure could indicate air has entered the pump.
  • Pump overheating: An overheated pump can be a symptom of air pockets preventing proper cooling.
  • Gurgling or sputtering noises: These sounds might indicate air trapped in the pump.
  • Difficulty starting: If your pressure washer struggles to start, it could be due to air in the pump.

When Should You Prime A Pressure Washer?

You should prime your pressure washer pump before each use, especially if the machine has been idle for a while or if you've recently changed any hoses or attachments. Air can easily get trapped in the pump when it sits unused or when components are disconnected, leading to performance issues.

Step-By-Step Guide to Priming a Pressure Washer Pump

  • Check for air leaks: Before you start, inspect the suction hose and connections. Make sure everything is tightly sealed to prevent any air from entering the pump.
  • Position the pressure washer: For optimal performance, place your pressure washer as close to the water supply as possible. The shorter the distance, the better the water flow.
  • Open Water Supply: Turn on the water supply and allow it to flow freely. Without connecting the high-pressure hose just yet, run water through the pressure washer. This helps remove any air and primes the pump.
  • Prime the pump: Most modern pressure washers have self-priming pumps. However, if your model requires manual priming, follow the manufacturer's instructions. This often involves opening a bleed valve or manually pumping the handle.
  • Run the pressure washer: Attach the water supply and switch on the machine. Let it run for about a minute to flush out any remaining air and free up any sticking valves.

Troubleshooting Priming Issues

If you notice the water pressure fluctuating, there could still be air trapped in the pump. To fix this:

  • Turn off the machine: Safety first! Always switch off the power before working on your pressure washer.
  • Disconnect the high-pressure hose: This allows any trapped air to escape from the system.
  • Check for air leaks: Inspect the suction hose and connections for any leaks.
  • Reconnect and repeat: Reconnect everything and try again until the pressure stabilises.
  • Consult the manual: If any issues persist, refer to your pressure washer's manual for specific troubleshooting guidelines.
