A clogged filter can restrict water flow and put unnecessary strain on the pump. By cleaning or replacing the water filter, you can ensure that your pressure washer pump is working efficiently. Additionally, it’s important to inspect the pump’s seals and valves for any signs of wear or damage.

If you notice any leaks or unusual noises coming from the pump, it may be a sign that the seals or valves need to be replaced. Finally, it’s a good idea to flush out the pump after each use to remove any dirt or debris that may have accumulated. This can help prevent clogs or blockages and extend the life of your pressure washer pump.

So, by following these tips and tricks, you can keep your pressure washer pump in top shape and ensure it continues to perform at its best.
