Water is recirculated in water pump storage tanks for how long?

• A. 30 minutes
• B. 1 hour
• C. 2 hours
• D. 15 minutes

Answer: (B)

Keeping water fresh and ready by circulating the full storage volume. Recirculating for one hour ensures every part of the water in the tank and its connected piping passes through the pump loop, flushing out any stagnant water, equalizing temperature, and maintaining proper disinfectant levels throughout the system. Shorter times may leave pockets of stagnant water, while longer times aren’t needed for readiness and waste time. Hence, one hour is the appropriate duration.
