Understanding Water Flow

In addition to pressure, water flow rate matters. A flow rate of around 2.5 to 3.5 GPM (gallons per minute) is usually adequate. This rate ensures a thorough wash while avoiding excessive force that may dislodge components.

Recommended Nozzle Types

Recommended Nozzle Types

Select a wide-angle nozzle, ideally between 25 to 40 degrees. This choice disperses water effectively and reduces the impact force, minimising the risk of surface breakage. Avoiding narrow nozzles is crucial, as they concentrate pressure in a small area and may harm the surface.

Regularly testing settings on a less visible area is prudent before proceeding to wider applications. Adjusting the pressure and flow incrementally allows for better control and reduces unintentional damage.
