Which item is NOT listed as a daily check for valve troubleshooting and maintenance?

• A. Visual inspection for leaks
• B. Temperature monitoring
• C. Unusual noise detection
• D. Pressure relief testing

Answer: (D)

During daily valve checks, the focus is on quick, observable signs that can indicate immediate issues without shutting everything down. Leaks, temperature rise, and unusual noises are typical daily indicators because they point to problems like worn seals, overheating, or loose components that you can spot or hear during routine rounds.

Pressure relief testing, on the other hand, is a safety function that verifies the valve opens at the correct set pressure to prevent overpressure conditions. Doing this test daily would be impractical and could disturb the system; it requires controlled procedures, depressurization where needed, and proper calibration. Because of these factors, it’s scheduled as part of periodic preventive maintenance rather than a daily check.

So the item not listed as a daily check is pressure relief testing. Visual leaks, temperature monitoring, and listening for unusual noises are the kinds of quick checks performed every day to catch problems early.
