How long must a section be tested with the minimum water head?

For plumbing systems, it is essential to ensure that they are leak-free and capable of handling the required pressure. The testing duration with the minimum water head is established based on industry standards and regulations. A section must be tested for a minimum of 15 minutes to guarantee the accuracy of the pressure test and to allow for any potential leaks to be detected.

This 15-minute time frame helps ensure that the entire section has been adequately assessed for integrity under pressure conditions that mimic actual usage scenarios. By adhering to this standard, plumbing professionals can maintain safety and reliability in their installations. In contrast, shorter testing durations may not provide sufficient time for a thorough evaluation, leading to undetected issues that could compromise the system's performance over time.
