Burst water heater: filing the insurance claim right

General information, not insurance advice. Your policy language controls — read it, and ask your agent what applies.

A water heater lets go quietly: forty to eighty gallons, plus the supply line feeding it, running until someone notices. It's one of the most common winter water claims — tanks fail more when incoming water turns cold — and one of the most winnable, if the first day is documented properly. It's also a claim with two traps built in: what's covered isn't what you think, and one word — «gradual» — can sink it.

Trap one: the heater itself usually isn't covered

Homeowners policies cover the resulting damage — floors, drywall, cabinets, the boxes of stuff stored next to the tank — but commonly exclude the appliance that failed, because equipment wearing out is a maintenance issue, not a peril. Expect to buy the new tank yourself and claim everything the water touched. Knowing this up front keeps the conversation with the adjuster clean.

Trap two: sudden vs. gradual

Policies pay for sudden and accidental water discharge and deny gradual leaks as neglect. Adjusters look for rust trails, old water staining, a corroded base — signs the tank had been weeping for months. If your tank genuinely burst, say so plainly and date it: when you last saw the area dry, when you found the water, photos with timestamps. A dated record beats an adjuster's guess about how long the leak existed.

The first hours, in order

• Stop the water — cold-line valve above the tank, or the house main.
• Cut power/gas — breaker for electric, gas valve for gas units.
• Document before touching anything — video walk-through plus photos: the tank's failure point, the data plate (brand, model, serial, manufacture date), standing water, each room, damaged items in place.
• Then mitigate — your policy requires preventing further damage: move belongings, run fans, call the emergency plumber. Keep every receipt; mitigation costs are typically claimable.
• Report the claim promptly and note who you spoke to and when.

Keep the evidence, run the diary

Don't dispose of the tank until the insurer confirms in writing — it's the proof of what failed, and if a defective part or bad install is to blame, the insurer's recovery from the manufacturer works in your favour. From there the claim is won by the boring machinery: photograph everything damaged item by item, log every call with date and name, save every receipt (plumber, fans, dehumidifier rental, hotel if you had to leave), and answer document requests same-week. Slow, complete, dated — that's what gets paid.
