Water heater leaking? What to do right now
Shut it down
- Close the cold-water supply valve at the top of the tank
- Electric: turn off the water heater breaker
- Gas: turn the gas control to off or pilot
- If you can't reach the valve, shut off the main water
Figure out where it's leaking
A leak from the temperature and pressure relief valve or a fitting may be repairable. Water coming from the bottom of the tank usually means the tank has rusted through and needs replacement.
Protect the house
In DFW, water heaters are often in garages, hall closets or attics. A garage leak may just need mopping. A closet or attic leak can soak flooring, walls and ceilings. If water reached drywall or carpet, get it extracted and dried quickly. See appliance leak cleanup.
Repair or replace
Tank water heaters usually last around 8 to 12 years. If yours is in that range and the tank is leaking, replacement is typical. A licensed plumber should install it, with a drain pan and, for attic units, a drain line. Many cities require a permit for water heater replacement.
Questions
Is a leaking water heater dangerous?
The hot water can scald, and a failing relief valve is a safety concern. Shut off water and power or gas, and keep people away.
Does insurance cover a water heater leak?
The resulting water damage from a sudden failure is often covered. The water heater itself usually isn't.
