When using a test gauge, what range is considered acceptable for a proper plumbing system test pressure?

The acceptable range for a plumbing system test pressure is 10 psi to 100 psi. This range is considered appropriate because it allows for the identification of any potential leaks in the system while ensuring that the pressure is high enough to test the integrity of the plumbing components effectively. A lower range might not sufficiently stress the pipes and fittings to reveal potential weaknesses or leaks, while a range above 100 psi could impose excessive pressure on the system, risking damage or failure during testing.

Testing within this range helps ensure that the plumbing system can withstand typical operational pressures encountered under normal use, providing confidence in the reliability of the system. By adhering to the standard testing range of 10 psi to 100 psi, plumbers can ensure compliance with safety codes and standards while effectively evaluating the plumbing installation.
