What is the minimum hydrostatic test pressure?

• A. 500 PSI
• B. 1000 PSI
• C. 750 PSI
• D. 600 PSI

Answer: (A)

Hydrostatic testing checks that hoses, fittings, and connectors won’t fail when pressurized. For MWS components, the standard minimum hydrostatic test pressure is 500 psi. This level provides a safety margin above normal operating pressures, helping reveal weak spots or leaks that wouldn’t appear at lower pressures. Pressures like 600, 750, or 1000 psi would exceed the minimum and unnecessarily stress the equipment during testing, so 500 psi is the typical minimum used.
