What test must be passed to verify the integrity of a plumbing system before it is put into service?

• A. Leak test
• B. Hydrostatic test
• C. Air pressure test
• D. Backflow test

Answer: (B)

To verify the integrity of a plumbing system before it is put into service, a hydrostatic test is performed. This test involves filling the plumbing system with water and then pressurizing it to a specified level. The goal is to check for leaks and ensure that the system can withstand the pressure it's designed for without failure. The hydrostatic test is especially significant because it simulates the stresses the pipes will experience when in actual service, allowing for the identification of any weaknesses or issues within the system. While a leak test generally refers to checking for leaks, it is not as rigorous as a hydrostatic test, which demands the system to be filled with water under pressure for a specified period. An air pressure test, although useful in certain scenarios, does not provide the same comprehensive verification for a plumbing system's integrity as a hydrostatic test does, particularly when checking for leaks in the presence of moisture. Backflow tests are related to ensuring that contaminants do not enter the potable water supply and do not assess the structural integrity of the plumbing system itself.
