Is bypassing a pressure regulator allowed?

Is bypassing a pressure regulator allowed?

• A. Yes, under certain conditions
• B. No
• C. Only with written authorization
• D. Only during testing

Answer: (B)

The main idea here is that a pressure regulator protects the system by keeping downstream gas pressure within safe limits. Bypassing it removes that protection, allowing the full supply pressure to reach pipes and appliances. That can cause overpressure, equipment damage, leaks, improper combustion, venting problems, and a real risk of fire or explosion. Because of these safety and code implications, bypassing is not permitted under any normal operation or testing scenario. Any work on the system must preserve proper regulation or use approved testing methods with proper equipment, not a bypass. So the correct answer is that bypassing a pressure regulator is not allowed.
