What is the required annual test pressure for supply hoses?

Answer: C — 200 psi

The required annual test pressure for supply hoses is indeed 200 psi, which is important for ensuring that the hoses can withstand operational pressures and potential surge pressures in the fire suppression system. This test helps identify any weaknesses or leaks within the hose, which could jeopardize water delivery during firefighting operations. Testing at 200 psi provides a safety margin that is essential for maintaining the integrity of the hose while also ensuring compliance with industry standards, particularly those set by organizations like the National Fire Protection Association (NFPA). Meeting or exceeding this testing pressure helps to confirm that the hoses are reliable and ready for any emergency response needs they may face.
