What is the standard pressure for conducting an air test on plumbing systems?

The standard pressure for conducting an air test on plumbing systems is typically set at 100 psi. This pressure is established to ensure that the plumbing system is tested adequately for leaks and proper functionality.

When performing an air test at this pressure, it allows for a sufficient differential to identify any potential weaknesses in joints, pipes, and fittings. Testing at lower pressures may not pinpoint leaks effectively, as they could require a higher force to expose weaknesses.

Additionally, regulatory guidelines often specify 100 psi as a standardized practice, making it a widely accepted benchmark in the plumbing industry. This consistency across jurisdictions helps ensure that plumbing systems are safe and reliable, meeting the necessary building codes and standards.
