In hydrostatic testing of standpipes, what is the primary purpose?

• A. To test electrical systems related to pumping.
• B. To measure water temperature at outlets.
• C. To verify the integrity of piping and joints and to identify leaks or failures.
• D. To evaluate finish color.

Answer: (C)

Hydrostatic testing of standpipes is about confirming the piping network’s physical integrity under pressure. By filling the standpipe with water and raising it to a specified test pressure for a set period, you stress joints, fittings, and the pipe itself. Any leaks, cracks, or weak connections will reveal themselves as pressure loss or visible leaks, allowing you to verify that the system is watertight and capable of carrying the intended standby water. This testing focuses on the structural and sealing quality of the piping, not on electrical systems, water temperature, or cosmetic finish.
