How often shall stand pipes with hose stations equipped with pressure reducing valves be tested?

• A. Every 3 years
• B. Every 5 years
• C. Every 7 years
• D. Every 10 years

Answer: (B)

Standpipes with hose stations use a pressure reducing valve to keep the hose outlet pressure within safe and usable limits. Because the valve’s internal components can wear or drift over time, a periodic check is needed to confirm it still reduces pressure to the intended level during flow and that it seals properly when not in use. Testing on a five-year cycle verifies the valve’s performance, including measuring inlet and outlet pressures under flow, ensuring the correct downstream pressure is achieved, and checking for leaks or improper operation. This interval reflects a balance between ensuring reliable operation of the pressure-regulating device and keeping maintenance manageable; more frequent checks are generally not required unless your local code or the system’s risk profile calls for it.
