Determining the appropriate nozzle size for a pressure washer involves considering the machine’s flow rate, measured in gallons per minute (gpm), and the desired cleaning intensity. A tool designed to facilitate this process often takes the form of a chart or an online application. For example, a user might input their pressure washer’s flow rate and desired pressure, and the tool would recommend a corresponding nozzle size, typically identified by a number or color code.
Correct nozzle selection is crucial for efficient and safe pressure washing. Using an undersized nozzle can lead to overworking the pump and premature wear. Conversely, an oversized nozzle may result in inadequate cleaning power. Historically, selecting the right nozzle often relied on trial and error or consulting manufacturer guidelines. Modern tools streamline this process, promoting optimal performance and prolonging equipment lifespan.
