What is the minimum pressure for a water test in a storm and sanitary system?

• A. 5 psi
• B. 10 psi
• C. 10 ft wc
• D. 100 ft wc

Answer: (C)

The minimum pressure for a water test in a storm and sanitary system is specified as 10 feet of water column (wc). This measurement is significant because it provides a quantifiable standard for testing the integrity of piping systems. The water column measurement is a way to represent pressure in terms of the height of a column of water that the pressure can support. In practice, a pressure of 10 feet of water column equates to approximately 4.3 psi. This value is used because it is an easily measurable standard that ensures the system can withstand typical operational pressures and potential leaks can be detected effectively. The use of 10 feet wc is particularly relevant in plumbing design as it reflects the pressure exerted by a column of water that is sufficient to identify leaks or weaknesses in the system components, while ensuring compliance with applicable plumbing codes and standards. A higher pressure might not be necessary or practical for typical testing scenarios, while lower pressures may not sufficiently validate the system's integrity. Therefore, this standard is crucial for ensuring that storm and sanitary systems are functioning safely and effectively.
