Hydrostatic testing applies to which scenario?

Hydrostatic testing applies to which scenario?

• A. New installation
• B. Existing system
• C. Repair
• D. Expansion

Answer: (A)

Hydrostatic testing is a commissioning test used to verify that a newly constructed system can safely withstand pressure before it is placed into service. By filling the system with water and pressurizing it to a level above normal operating pressure, you can reveal hidden defects in welds, joints, or components and confirm overall strength and leak-tightness. This requirement is most clearly applied to a new installation because it ensures the entire system meets safety and integrity standards before any product is stored or transferred. For existing systems, testing is not typically done as a routine step; repairs, alterations, or expansions may necessitate testing, but the primary scenario where hydrostatic testing is standard is when a new installation is being commissioned.
