How many minutes is the required testing duration when using air pressure at 5 PSI?

5 Minutes
10 Minutes
15 Minutes
20 Minutes

The correct answer is: 15 Minutes

When conducting a test using air pressure at 5 PSI, the required testing duration is 15 minutes. This duration is established to ensure that any potential leaks in the plumbing system can be effectively detected. A 15-minute testing period at this pressure allows for sufficient time to monitor the system's stability and accurately assess whether the plumbing is holding the pressure properly. In plumbing practice, longer test durations help to compensate for minor fluctuations in pressure that may occur naturally or due to temperature changes. Testing for a full 15 minutes is a standard procedure that adheres to industry guidelines, providing a reliable measure of the system's integrity. Shorter durations, such as 5 or 10 minutes, might not provide enough time to identify slow leaks, which could lead to future issues if not addressed.
