Recently had a water heater call where we eventually determined the gas was off, but the customer didn’t know it. With the recent earthquakes, people should check to see if a quake may have tripped their gas cut-off valve (if one has been installed) before they call for service. If you have one of these valves, make sure you know how to reset it yourself. Should the big one hit, it could take the gas company weeks or longer before they are able to service all the people who need them.
