What is the purpose of hydrostatic pressure testing a new water main?

• A. Determines the total dynamic head
• B. Verify the exterior strength of the pipe
• C. Calculate the static pressure in the new water main when the closest water tank is full of water
• D. Determine that all pipes, valves, and fittings were installed properly by checking for visible leaks, and monitoring the water pressure, which will drop if there are leaks

Answer: (D)

The purpose of hydrostatic pressure testing a new water main primarily focuses on ensuring the integrity and reliability of the installed system. Hydrostatic testing involves filling the system with water and subjecting it to pressure beyond its normal operational levels to check for any leaks or weaknesses. When option D is the selected answer, it reflects the comprehensive objectives of the hydrostatic test. This testing method serves to verify that all components, including pipes, valves, and fittings, have been installed correctly. By monitoring for any visible leaks and measuring the water pressure during the test, operators can identify potential failures before the system goes into service. If there are any leaks, the pressure will typically drop, indicating areas that need repair or adjustment. This approach is crucial to maintaining the safety and functionality of the water distribution system, as even minor leaks can lead to significant issues over time, such as water loss, contamination, and structural integrity failures. Thus, the focus on monitoring pressure and detecting leaks makes option D the most accurate representation of the testing's purpose.
