For a system in a single-family dwelling with a volume less than 10', how long should the test last?

The correct duration for testing a system in a single-family dwelling with a volume less than 10 cubic feet is specified to be between 10 minutes to 24 hours. This time frame is established to ensure that sufficient time is allotted for the examination of the system, allowing for the identification of any potential leaks or issues.

In a residential setting, particularly with smaller volumes, it's important to balance a thorough examination with practical time constraints. The 10-minute minimum ensures that the system has adequate time to stabilize and display any issues that may arise, while the maximum of 24 hours accommodates extensive testing to confirm that systems remain leak-proof and function as intended.

Testing for less than this time frame could lead to incomplete assessments, failing to catch issues that may only manifest after a period of operation. Proper adherence to this time guideline not only aligns with safety standards but also helps promote the reliability of gas systems in residential applications.
