Quick answer

Turn off the cold-water supply valve on top of the heater, then shut off the gas or flip the breaker. Water leaking from the bottom of the tank usually means it has failed and needs replacing, which requires a permit in Gainesville. A sudden rupture is usually covered for the water damage, but not for the heater itself.

  1. Turn off the cold water supply at the valve on top of the tank. If it will not turn, close the main water valve.
  2. Shut off the energy. For an electric heater, switch off its breaker. For gas, turn the control knob to off or pilot. If you smell gas, leave and call 911.
  3. Do not touch the drain valve or pressure relief valve unless you know what you are doing. The water inside can scald.
  4. Photograph the heater, its label, and the wet areas. The label shows the age.
  5. Get the water up and check the walls and flooring around the heater for wicking.

What should Gainesville homeowners know about water heater leaks?

  • Replacement needs a permit. The City of Gainesville lists water heater replacement among the projects that need a building permit (City of Gainesville). Unincorporated Hall County also requires a permit to install or replace a water heater (Hall County). Ask your plumber to pull it.
  • The water here is soft. Gainesville's tap water averaged 21.2 ppm hardness in 2025, about 1.23 grains per gallon (City of Gainesville). That makes heavy hard-water scale less likely, so a leak from the tank body is usually a sign of age or corrosion.
  • High water bill from the leak? Once it is fixed, you can ask the city for a leak adjustment (City of Gainesville).

Where is the water heater leak coming from?

  • Leaking from the bottom: usually the tank itself has failed. It needs to be replaced, not repaired.
  • Pipe connections on top: often a loose fitting or failed supply line, which a plumber can fix.
  • Pressure relief valve or its discharge pipe: can point to a pressure or temperature problem. Have a plumber check it before using the heater again.
  • Drain valve: a dripping valve can sometimes be tightened or replaced.

What about washer, dishwasher, and fridge leaks?

  • Washing machine: a burst supply hose can release water at full house pressure until someone shuts it off. Close the valves behind the washer.
  • Dishwasher: leaks often run under the cabinets and into the subfloor before they show. Turn off the valve under the sink.
  • Refrigerator ice maker line: a slow drip behind the fridge can soak flooring for weeks. Close the supply valve, often under the sink or in the basement.

For any appliance leak, unplug the appliance if you can do it from a dry spot, then check the floor and wall behind it.

What does a restoration company do after a water heater leak?

  • Extracts water from the floor and nearby carpet
  • Checks the walls, subfloor, and any finished rooms below with moisture meters
  • Removes damaged baseboards, drywall, or flooring that cannot be dried in place
  • Dries the area with dehumidifiers and air movers until readings are normal

The plumber replaces the heater. The restoration company deals with the water it left behind.

Does insurance cover water heater leak damage?

A sudden rupture is usually covered for the damage the water caused. A heater that leaked slowly for months often is not, and the policy typically does not pay for the heater itself (GEICO). See what homeowners insurance covers.

Common questions

Can I keep using a leaking water heater?

No. Shut off the water and power or gas until a plumber has looked at it. A tank that leaks from the bottom will only get worse.

How long do water heaters last?

Tank heaters often last around 8 to 12 years. Check the label or serial number for the manufacture date.

Do I need a permit to replace it myself?

In the city of Gainesville and unincorporated Hall County, water heater replacement requires a permit. Call the building office for homeowner rules.
