Which of the following is one of the Pre-Service tests?

• A. Hydrostatic Test
• B. Final Acceptance Test
• C. On-site Readiness Test
• D. User Training Test

Answer: (A)

Before a Mobile Water Supply system goes into service, the piping and components must be proven to handle the pressures they’ll face. A hydrostatic test accomplishes this by filling the system with water and pressurizing it above normal operating pressure for a defined period. This method reveals leaks, cracks, or weak joints without introducing air into the lines, ensuring the entire water path—tanks, hoses, valves, and fittings—is sound before use. The other tests are staged differently: a Final Acceptance Test occurs at the end of construction to confirm all requirements are met; an On-site Readiness Test focuses on whether the site and setup are ready for operation; a User Training Test checks that personnel have completed training.
