How long do water heaters last here?
Tank water heaters often last about 8 to 12 years. Arizona’s hard water leaves mineral scale in the tank that can shorten that. If you do not know your heater’s age, check the serial number sticker or ask a plumber.
Warning signs of failure
- Rust-colored water or a metallic taste
- Rumbling or popping noises from sediment
- Moisture or rust around the base or fittings
- Inconsistent hot water
- A tank that is over 10 years old
Maintenance that helps
- Flush the tank once a year to remove sediment
- Test the temperature and pressure relief valve
- Have the anode rod inspected, since it protects the tank from corrosion
- Install a drain pan with a drain line, or a leak sensor, if the heater sits indoors
What to do if it is leaking
Turn off the cold water supply to the heater, shut off power (breaker) or gas, and open a hot water tap to relieve pressure. Then call a plumber, and a restoration provider if water has spread. See water leak damage restoration and water extraction.
Consider a leak sensor and shut-off valve
An automatic shut-off valve cuts the water when a sensor detects a leak. It can turn a flooded garage into a minor cleanup.
Quick answers
Is a leaking water heater an emergency?
Yes. Shut off water and power or gas, then call. A failing tank can release dozens of gallons.
Does insurance cover a water heater leak?
Resulting water damage is often covered when the failure is sudden. The heater itself usually is not. Check your policy.
