What is the typical pressure for low pressure gas distribution throughout a building?

• A. 0.5 psi
• B. 1 psi
• C. 1.5 psi
• D. 2 psi

Answer: (A)

The typical pressure for low pressure gas distribution throughout a building is 0.5 psi. This is because low pressure distribution systems are designed to safely deliver gas to various appliances within a building without exceeding the capabilities of the appliances themselves or the piping system. Gas appliances, such as furnaces and water heaters, generally operate efficiently at this lower pressure level, ensuring that there is a stable supply without the risk of leaks or overpressure situations. In many codes and standards, 0.5 psi is defined as the threshold that characterizes low pressure gas systems, making it a common choice for residential and light commercial applications. This pressure allows for a balance between sufficient delivery of gas while maintaining safety and regulatory compliance in plumbing design.
