What is the maximum length of hose for Class II standpipe systems?

Explanation:
Class II standpipes are designed to give occupants a ready-to-use handline, typically a 1.5-inch hose. The hose length is set at 50 feet to provide enough reach from a standpipe outlet to most areas on a floor while keeping the hose manageable to carry and maneuver. Longer hoses would be heavy and accrue more friction loss, reducing nozzle pressure, while shorter hoses might not reach into many rooms. So a 50-foot hose balances reach with handling and performance.
