Inspection requirements for water supplies, standpipe hose valves, regulating devices, and fire department connections (FDCs) focus on accessibility, operability, condition, and identification. Water supplies must be inspected to ensure control valves are open, properly supervised, clearly labeled, and free of leaks or damage. Standpipe hose valves must be accessible, unobstructed, properly capped, free of corrosion, and securely mounted at the correct height. Pressure-regulating devices must be visually inspected to confirm correct installation, intact seals, proper settings, and absence of damage or tampering.

Fire department connections must be visible, unobstructed, clearly marked, equipped with approved caps, and free of debris or deterioration. Inspectors also verify that signage is present and connections are compatible with local fire department equipment. Inspection frequency and procedures are typically guided by NFPA 25, which establishes standards to ensure systems will function reliably during a fire event.
