During hose testing, what is the maximum length of the connected hose?

• A. 100 feet
• B. 300 feet
• C. 500 feet
• D. 1000 feet

Answer: (B)

When testing hoses, you want to balance the length of the connected run with the ability to maintain the required test pressure. Friction losses grow with longer hose lengths, so if the connected hose is too long, the pump must deliver much more pressure to achieve the same pressure at the far end, making the test unreliable and potentially unsafe. A length of 300 feet keeps the test representative of real-world use while keeping friction losses manageable and within the pump’s capability. Longer lengths would push friction losses higher and could mask leaks or damage, while shorter lengths wouldn’t adequately simulate longer hose runs.
