What to Do Right Now
A failed water heater is aggravating — a few quick steps keep the situation safe while help is on its way.
If you see water spreading from the unit, close the cold-water shutoff valve feeding the water heater if you can reach it safely. It is usually a lever or a wheel on the pipe entering the top of the tank. Keep away from standing water near electrical outlets, and never touch a wet electric water heater or its wiring with wet hands.
For a gas unit, if you smell gas, leave the area and contact your gas utility or emergency services first — then call a plumber once it is safe to be there. Do not keep relighting a pilot that will not stay lit; a pilot that repeatedly dies is pointing at a fault that needs professional attention.
Leave the access panels on and the tools in the drawer. Inside that cabinet, pressurized hot water shares space with gas or high-voltage wiring, and the margin for a curious mistake is measured in scalds and floods. This equipment rewards professional hands and punishes improvisation.
