Mechanical waterflow devices, including water motor gongs, shall be tested ______.

Mechanical waterflow devices, including water motor gongs, shall be tested ______.

• A. Daily
• B. Weekly
• C. Monthly
• D. Quarterly

Answer: (D)

Mechanical waterflow devices, such as water motor gongs, are flow-activated indicators that must be proven ready to respond to water movement. They can suffer from wear, seized parts, or obstructions that prevent proper action, so regular testing confirms that when water starts to flow, the device spins and the gong sounds, and that any related signaling or supervisory circuits function and report to the monitoring system. The quarterly interval provides a reliable balance between catching mechanical issues in a reasonable timeframe and not overloading maintenance with overly frequent checks. Testing more often (daily, weekly) isn’t typically necessary for these devices, and waiting longer than quarterly (monthly or yearly) risks undetected failures.
