Choosing nozzles carefully can significantly enhance performance even in circumstances of inadequate flow. A wider nozzle reduces the intensity of the stream, which can help maintain adequate cleaning ability while optimising the available supply. Consider going for a 25-degree or 40-degree nozzle, as they offer a broader spray pattern, distributing water more effectively across surfaces while using less force.

Another technique involves altering your technique during application. Maintaining a consistent distance from the surface ensures that the force is not lost. Staying closer (but not too close) allows the stream to maintain its effectiveness without overwhelming the surface or causing damage. Make sure to move at a steady pace to achieve uniform results.

Additives designed for cleaning can enhance the efficiency of the system when supply is lacking. Using specific detergents or cleaning solutions can aid in loosening grime and dirt, reducing the reliance on water alone for powerful cleaning action. However, pre-diluting these products is often necessary to prevent clogging and maintain proper flow.
