Water heater leaking: what to do first
Cut the energy, close the cold water, then call: those three moves, in that order, limit the damage while the plumber is on the way.
- Cut the energy supply. For an electric unit, switch off its breaker at the panel. For a gas unit, turn the burner to pilot or off, following the label on the appliance. If you smell gas, leave the house and call your gas utility before doing anything else.
- Close the cold water valve. It sits on the pipe that enters the top of the tank. The unit stops refilling and the leak slows down.
- Protect and document. Move boxes and belongings off the floor, let the water run toward a floor drain if it is heading there, and take a few photos for your insurer.
- Call us. Someone on the team picks up and tells you what to check while the plumber is on the way.
