Why Is My Water Heater Leaking?
Finding water around your water heater can be alarming.
A water heater leak can have several possible causes, and the location of the water matters.
Where Is the Water Coming From?
Water may appear:
Around the bottom of the tank
Near a connection
Around a valve
Near the top of the unit
Around piping
The visible water isn't necessarily coming from the place where you first notice it.
Common Causes of Water Heater Leaks
Loose or Damaged Connections
Connections and fittings can develop leaks.
Valve Problems
A valve may be leaking or releasing water.
Corrosion
Corrosion can eventually compromise components or the tank itself.
Tank Failure
If the tank itself has developed a serious leak, replacement may be necessary.
Is a Leaking Water Heater an Emergency?
A significant leak can cause water damage, so it shouldn't be ignored.
If water is actively flowing, turn off the water supply to the unit if you know how to do so safely and contact a plumber.
Can a Leaking Water Heater Be Repaired?
Sometimes.
The appropriate solution depends on the source and severity of the leak and the condition of the water heater.
