Water piping pressure shall be maintained for a minimum duration of?

The requirement to maintain water piping pressure for a minimum duration of 15 minutes is essential for testing the integrity and reliability of plumbing systems. This duration allows for sufficient time to observe any pressure loss that may indicate leaks or weaknesses in the piping system.

When a plumbing system is pressurized, it's important to ensure that the materials used, the joints, and fittings can withstand operational pressures without failing. The 15-minute timeframe has been established as a standard in the plumbing industry, providing a balance between thoroughness and efficiency.

Maintaining pressure for this length of time not only helps in identifying immediate issues but also ensures that the system can perform well under regular usage conditions, minimizing future maintenance needs and potential water damage. Such pressure testing protocols are critical for safeguarding the long-term functionality and safety of plumbing installations.
