Abstract
A gas system, such as an appliance or a building has a pressure sensor intermediate a master solenoid valve and at least one valve, wherein when the at least one valve is closed, shut or off, and the master solenoid valve is off, the pressure sensor senses pressure and if pressure drop over a given time exceeds a predetermined amount, an alarm condition is identified (indicating a leak). The master solenoid valve may be maintained shut until the leak is addressed.
