Checking the Water Supply and Connections
Start by ensuring a consistent water source. If the flow is insufficient, it will impact the device’s performance. Use a bucket to measure the water output; a minimum of 7 litres per minute is ideal for optimal functioning.
Inspecting Hoses and Connectors
Examine all hoses for kinks, cracks, or blockages. Even minor leaks can significantly reduce the water flow. Ensure that your connectors are tightly fastened to prevent any air from entering the system, as this can lead to reduced efficiency. I once encountered an issue where a simple loose connection caused a significant drop in output. Tightening it resolved the problem immediately.
Water Quality Considerations
Check the quality of the water being used. Sediment and debris can clog filters and restrict flow. If the water is murky or contains particles, consider using a filter or regularly cleaning the inlet screen. In my experience, maintaining clean water not only enhances performance but also prolongs the lifespan of the unit.

Examining the Nozzle for Blockages
Inspect the nozzle for any debris or clogs. A restricted nozzle can significantly impact the flow of water, leading to inadequate performance. Start by removing the nozzle from the lance. Use a small, soft brush or a toothpick to gently clear any obstructions. Rinse the nozzle thoroughly under running water to ensure all particles are dislodged.
Different nozzles produce various spray patterns, which can affect cleaning efficiency. If you’re using a narrow nozzle and it’s partially blocked, the pressure will drop. Always match the nozzle size to your cleaning task. For heavy-duty grime, a more powerful nozzle is advisable, while a wider spray is better for delicate surfaces.
| Nozzle Type | Recommended Use | Typical Pressure |
|---|---|---|
| 0° (Red) | Heavy cleaning, stubborn stains | High |
| 15° (Yellow) | Concrete, brick | Medium to high |
| 25° (Green) | General cleaning | Medium |
| 40° (White) | Washing vehicles, delicate surfaces | Low to medium |
| Soap (Black) | Applying detergent | Low |
After clearing the nozzle, reattach it and test the equipment. If water flow improves, you’ve resolved the issue. If not, further investigation is necessary. Consider checking the lance for blockages, as dirt can accumulate there too. Regular maintenance of the nozzle will prolong its lifespan and ensure optimal performance for your cleaning tasks.
Inspecting the Pressure Hose for Leaks or Damage
First thing to do is visually inspect the hose for any signs of wear or leaks. Look closely for cracks, abrasions, or pinholes that might be allowing water to escape. Even a small puncture can lead to a significant loss of force.
Next, run your fingers along the length of the hose while applying pressure. This can help you feel any weak spots or bulges that might indicate internal damage. Pay special attention to the fittings at both ends, where the hose connects to the unit and the lance. These areas are common culprits for leaks.
If you suspect a leak, a simple test is to spray soapy water along the hose. If you see bubbles forming, you’ve identified the problem area. Make sure to turn off the unit and relieve any built-up pressure before inspecting or making repairs.
In cases of severe damage, replacing the entire hose might be necessary. Look for hoses that match the specifications of your model to ensure compatibility. For minor issues, you might be able to use a hose repair kit, which typically includes connectors and seals.
