True or False: The minimum pressure rating of a fitting must be equal to or greater than the maximum allowable operating pressure of the system.

The statement is true because the minimum pressure rating of any fitting in a distribution system must meet or exceed the maximum allowable operating pressure to ensure safety and reliability. This principle is fundamental in engineering and plumbing practices, as fittings are critical components that must withstand the pressures exerted within the system. Using a fitting with a lower pressure rating than the operating pressure could lead to failures such as leaks or catastrophic ruptures, posing risks to both the system and the surrounding environment.

This adherence to pressure ratings is vital for maintaining the integrity of the entire distribution system. It ensures that under typical operating conditions, which may include pressure variations due to system changes or environmental factors, the fittings will function properly without degradation or failure.
