What should you do if your water heater is leaking?
Turn off the power or gas to the heater, then close the cold water supply valve on top of it. Drain a little water if the tank is still leaking, and keep people away from hot water. Call a plumber for the heater and a water pro to remove water and dry the area.
Most tank water heaters last roughly 8 to 12 years. When the tank rusts through or a fitting fails, it can release 40 to 80 gallons at once. In many local homes the heater sits in a garage, a utility closet or a hall alcove. Water runs under walls into carpet, laminate and drywall before you notice.
A leak from a valve or fitting is a smaller problem than a tank that has split. Either way, wet flooring and drywall around the heater need to be dried. Call (480) 555-0143 and we will connect you with a local provider. A leaking tank can put gallons on the floor quickly, and professional water extraction services can remove it while you arrange a plumber.
What should you do right now?
- Cut the power. For an electric heater, switch off its breaker. For gas, turn the gas control knob to off or pilot.
- Close the cold supply valve. It is the shutoff on the pipe going into the top of the heater. Turn it clockwise. If it is stuck, shut off the main water valve.
- Be careful with hot water. Do not touch the tank or pipes, and do not step into hot pooled water.
- Attach a hose to the drain valve only if you can do it safely, and run it outside or to a floor drain.
- Move items off the floor around the heater: paint cans, boxes, tools and shoes.
- Photograph the tank, the label with its age and the wet areas.
- Call a plumber and call (480) 555-0143 for cleanup.
What are the signs you need water heater leak cleanup?
Water heaters often give warnings before they fail. Look for:
- Water pooled around the base of the tank
- Rust-colored drips at the pipe fittings or the bottom
- Rusty or cloudy hot water
- Rumbling or popping noises from sediment in the tank
- Dripping from the pressure relief valve pipe
- A tank older than about 10 years
- Damp drywall or baseboards in the closet or hall near the heater
- Warped flooring near the utility closet
How does the process work?
- Make the area safePower or gas is off and the water supply is closed. The pro checks for hot water and electrical risks.
- Remove standing waterWater is pumped or vacuumed from the floor. In garages it may also be pushed out the door. See emergency water extraction.
- Check nearby walls and floorsMoisture meters show whether water went into drywall, a shared wall or the flooring next door.
- Remove ruined materialsWet baseboards, bottom sections of drywall and soaked carpet or padding are cut out if they cannot be saved.
- Dry the areaFans and a dehumidifier run until the readings are normal. A plumber replaces the heater on their own schedule.

Why are water heaters often the problem in local homes?
Many homes here place the heater in a garage or a utility closet with no floor drain. When the tank leaks, water has nowhere to go but under the wall and into finished rooms. Heat in garages also speeds wear on valves and fittings.
A drain pan with a pipe that leads outside can help catch a slow leak. A plumber can tell you what your home needs.
What about a tankless heater?
Tankless heaters do not hold a big reserve of water, so a leak is usually smaller. But they can still leak at connections and from condensation lines. If you see water near yours, shut off the supply and call a plumber. Wet drywall or flooring still needs drying.
