What should be done during the hydrostatic test to ensure that no portion of the piping is subject to freezing?

• A. Care should be taken to ensure that no portion of the piping is subject to freezing during cold weather
• B. Place ice around the test area
• C. Only test during warm weather
• D. Ignore freezing risk

Answer: (A)

Preventing freezing during hydrostatic testing is essential because water inside the pipes can freeze and expand, causing damage and making the test unreliable. The correct approach is to take precautions so no portion of the piping experiences freezing—keep the area warm, insulate exposed runs, circulate heated water, or perform the test in conditions where freezing won’t occur. The other ideas—adding ice, testing only in warm weather as a rule, or ignoring freezing risk—would promote freezing or ignore the risk, which is unsafe and not in line with good practice.
