What is the maximum length, in feet, for a standard 1 3/4 inch cross lay?

• A. 200 ft
• B. 250 ft
• C. 300 ft
• D. 350 ft

Answer: (C)

The length limit hinges on keeping enough pressure at the nozzle after accounting for friction losses in the hose. A standard 1 3/4 inch cross lay is designed for a balance between reach and the operator’s ability to maintain a usable flow. As hose length increases, friction loss grows and the line becomes heavier, which reduces the pressure available at the nozzle and makes it harder to advance and control the stream. About 300 feet is the practical upper limit where you can still maintain effective nozzle pressure with typical pump settings; longer lengths would require excessive pump pressure and hinder maneuverability. If more reach is needed, a longer or additional line should be deployed through another method.
