Filters, Pressure Washing & Power Washing

Filters are crucial components in pressure washers, serving the essential function of removing impurities from the water supply before it reaches the pump. This protects the pump from damage caused by debris and contaminants that can clog its delicate internal components.

Types of Filters in Pressure Washers:

  • Water filters: These filters are typically installed at the inlet hose connection and remove sediment, sand, rust, and other particles from the water source. This significantly reduces wear and tear on the pump, extending its lifespan.
  • Fuel filters: Gas-powered pressure washers require fuel filters to remove dirt, dust, and other contaminants from the fuel supply. This prevents clogging of the carburetor and ensures smooth operation of the engine.
  • Air filters: Some pressure washers, particularly gas-powered models, utilize air filters to capture dust and debris from the air intake. This protects the engine from internal damage and ensures efficient combustion.

Importance of Filters:

  • Extend pump life: Filters prevent contaminants from entering the pump, minimizing wear and tear and extending its lifespan.
  • Protect internal components: By removing debris, filters protect delicate internal parts of the pressure washer from damage and malfunction.
  • Maintain performance: Clean filters ensure optimal performance of the pressure washer by preventing clogs and allowing for smooth water flow.
  • Reduce maintenance costs: Regular filter replacement minimizes the need for costly repairs and maintenance of the pressure washer.

Filter Maintenance:

  • Regular cleaning or replacement: Follow the manufacturer’s recommendations for cleaning or replacing the filters regularly. The frequency depends on factors like water quality and usage intensity.
  • Inspection: Regularly inspect the filters for signs of wear, damage, or clogging. Replace them immediately if any issues are detected.
  • Use the correct type of filter: Ensure you are using the correct type of filter designed for your specific pressure washer model.

Signs of Faulty Filters:

  • Reduced pressure: Clogged filters restrict water flow, leading to a decrease in pressure output.
  • Pump overheating: Impurities can cause the pump to overheat due to increased friction.
  • Uneven water flow: Clogged filters can lead to uneven water flow, resulting in streaking or inconsistent cleaning.
  • Noisy operation: Faulty filters can cause the pressure washer to operate at a higher noise level.
