TL;DR
A gas shutoff valve is any of the manual valves that stop gas flow in an installation — the main service valve at the meter, intermediate branch valves, and the appliance valve behind each range, dryer, and water heater. Handles run parallel to the pipe when open and perpendicular when closed, a convention worth knowing before an emergency.
What it means
A gas shutoff valve is any of the manual valves that stop gas flow in an installation — the main service valve at the meter, intermediate branch valves, and the appliance valve behind each range, dryer, and water heater. Handles run parallel to the pipe when open and perpendicular when closed, a convention worth knowing before an emergency. The meter valve usually needs a wrench, which is why utilities advise residents to know its location but to let professionals restore service, since relighting requires checking every pilot downstream.
