Commercial service lines can be up to how many psi?

• A. up to 60 psi
• B. up to 0.3 psi
• C. up to 12 psi
• D. up to 5 psi

Answer: (D)

Gas service lines to commercial buildings are treated as low-pressure conduits. They’re designed so the utility can regulate the pressure down to safe, appliance-friendly levels, and five pounds per square inch represents the upper limit typically allowed for a service connection. This keeps the line within the range that standard regulators and safety practices can manage. Pressures above this are not considered service lines and require different handling and equipment. So five psi is the standard maximum for commercial service lines, which is why that option is the best fit.
