Short answer: Usually the water damage, not the water heater. Standard homeowners policies generally cover sudden and accidental water damage from a water heater that bursts or suddenly leaks, such as soaked flooring and drywall. They usually don't pay to replace a heater that failed from age or wear, or for damage from slow leaks that went on for a long time.
What's typically covered
Under most homeowners policies, sudden and accidental discharge of water from a plumbing or heating system or household appliance is a covered peril. After a sudden water heater failure, the policy may cover:
- Damage to the home: floors, drywall, baseboards, cabinets
- Damage to belongings: furniture, rugs, stored items, subject to your personal property coverage
- Water extraction and drying
- Additional living expenses if the home is unlivable during repairs. See additional living expenses coverage.
Your deductible applies.
What's typically not covered
- The water heater itself, when it failed from age, corrosion or wear and tear
- Gradual leaks: continuous or repeated seepage over weeks or months
- Mold from long-term leaks, or mold beyond a limited sublimit. See water damage and mold claims.
- Neglect or poor maintenance
- Improper installation, in some cases
Some insurers offer equipment breakdown endorsements for homes that can cover mechanical or electrical breakdown of appliances like water heaters. See what does equipment breakdown insurance cover.
Sudden vs. gradual: why it matters
Adjusters look for evidence of how long the leak lasted: staining, rot, corrosion, mold growth and warped materials. A tank that ruptured overnight is a classic covered loss. A slow drip that rotted the subfloor over a year usually isn't.
California water heater rules
California requires water heaters to be braced, anchored or strapped to resist falling during an earthquake. See Health and Safety Code §19211. Local building departments enforce installation codes. Many home sales require compliance. A tank that tips over in a quake can break gas and water lines. Remember, earthquake damage is excluded from standard homeowners policies.
What to do after a water heater leak
- Shut off the water to the heater, or the main supply.
- Turn off power or gas to the heater.
- Stop further damage: move belongings, extract water, run fans.
- Take photos and video before cleanup.
- Call your insurer or broker promptly.
- Keep receipts for emergency repairs and drying.
- Save the failed parts if possible until the adjuster inspects.
Prevention
- Know your heater's age and replace it near the end of its expected life
- Inspect for rust, moisture and drips
- Flush sediment as recommended by the manufacturer
- Test the temperature and pressure relief valve
- Install a drain pan with a drain line
- Use a water leak sensor or automatic shutoff valve
- Keep the heater properly strapped
Some insurers offer discounts for water shutoff devices. Ask.
Renters and condo owners
Renters insurance generally covers your belongings damaged by a sudden leak, while the landlord's policy covers the building. Condo owners should check how the HOA master policy and their own policy split responsibility. See renters insurance and condo insurance.
Common scenarios
The tank ruptures overnight and floods the garage and hallway. Sudden discharge. Resulting water damage is typically covered, minus the deductible. The old heater usually isn't.
A slow drip from the relief valve stained the closet floor for months. Gradual leakage is usually excluded, and the rot may be too.
A new heater installed last month leaks because of a bad fitting. The resulting damage may be covered, and the installer may be responsible. Keep the installer's information and warranty.
A heater in a vacant rental leaks for weeks before anyone notices. Vacancy conditions and gradual-leak exclusions can limit coverage. See does homeowners insurance cover a vacant house.
Tankless heaters
Tankless units hold less water but can still leak at connections. The same sudden-versus-gradual rules generally apply.
