In the context of pressure testing for a single-family dwelling, the correct duration for which the pressure reading should remain stable is 10 minutes. This timeframe is established as a standard to ensure that any potential leaks are detected effectively.

Maintaining a stable pressure reading for 10 minutes allows for adequate time to identify any decrease in pressure, which could indicate a leak in the system. If the pressure drops within this period, it signals that the integrity of the piping or fittings may be compromised, necessitating further inspection and potential repairs.

This specific duration is recognized in various industry guidelines and safety regulations to ensure reliability and safety in gas systems. Shorter testing durations may not provide a comprehensive assessment of the system's integrity, whereas longer durations might be unnecessary and could lead to inefficiencies in the testing process. Thus, adhering to the 10-minute standard strikes the right balance between thoroughness and practicality in pressure testing protocols.
