A master plumber is working in a city that has adopted a local ordinance requiring a more stringent pipe material for a specific application than what is required by the state's adopted plumbing code. Which requirement must the plumber follow?
Answer: B. The local ordinance, as it is the more restrictive requirement.
A fundamental principle in code administration is that where different codes or regulations have jurisdiction, the most stringent or restrictive requirement shall govern. This ensures the highest level of safety and performance is met. Local amendments are often enacted to address specific local conditions or priorities.

A master plumber is installing a natural gas piping system with a proposed maximum working pressure of 0.5 psi. According to the IFGC, what is the minimum required test pressure and duration for this new piping system before any appliance is connected?
Answer: B. 3.0 psi for 10 minutes
The International Fuel Gas Code (IFGC) section 406.4.1 states that the test pressure to be used shall be no less than 1-1/2 times the proposed maximum working pressure, but not less than 3 psig (20 kPa gauge), irrespective of the design pressure. Since 1.5 times 0.5 psi is 0.75 psi, the minimum test pressure defaults to 3 psig. Section 406.4.2 specifies the test duration shall be not less than 10 minutes.
