What is the minimum working pressure for a plumbing system in NYC?

• A. 10 psi
• B. 15 psi
• C. 20 psi
• D. 25 psi

Answer: (C)

In New York City, the minimum working pressure required for a plumbing system is established at 20 psi. This standard ensures adequate water flow and pressure for fixtures and appliances throughout a building. The requirement helps to maintain reliable service, minimizing the risk of insufficient water pressure that could lead to operational issues in plumbing systems, particularly in high-rise buildings where gravity can significantly affect pressure. By setting the minimum at 20 psi, the regulations ensure that there is enough pressure to deliver water effectively to all areas of a building, thereby supporting public health and safety standards.
