Water Damage
Water Heater or Appliance Leak: Cleanup and Claims
When a water heater or appliance leaks, shut off the water to it first, then turn off its power or gas if you can do that safely. Take photos, get the water up, and start drying right away. For insurance, the water damage to your home is often treated differently from the broken appliance itself, which a standard policy usually does not replace.
Appliance leaks often happen in a basement, laundry room, or kitchen, and they can run for hours before anyone notices. Here is how to handle the cleanup and the claim.
First steps by appliance
Find the shutoff before you need it. Here is where to look:
| Appliance | Where to shut off the water | Power or gas | Things to watch |
|---|---|---|---|
| Tank water heater | Cold water valve on the pipe at the top of the tank | Electric: turn off its breaker. Gas: turn the control to Off, following the label on the tank. | Water may be hot. Let it cool before you touch it. |
| Washing machine | Two valves on the wall behind the washer | Unplug only if the plug and floor are dry | Check the fill hoses for splits and bulges |
| Dishwasher | Valve under the kitchen sink | Turn off its breaker | Water often spreads under cabinets and flooring |
| Refrigerator ice maker or water line | Valve under the sink or behind the fridge | Usually no need to unplug | Small lines can drip slowly for weeks |
| Air conditioner or furnace drain | Turn the system off at the thermostat | Turn off at the service switch if it is wet | A clogged drain line can overflow the pan |
If you cannot find the appliance valve, shut off the main water valve to the house. Every adult in the home should know where it is.
If you smell gas near a gas water heater, do not touch anything. Duke Energy says to evacuate everyone and call 911 and Duke Energy from a safe location, and not to use anything that could make a spark.
Cleanup checklist
- Photograph and video everything. Get the appliance, the leak point, the water on the floor, and anything wet. Do this before cleanup.
- Remove standing water. Use towels, a mop, or a wet/dry vacuum.
- Pull up wet rugs and move belongings. Lift furniture off wet flooring.
- Check under and behind. Water spreads under cabinets, baseboards, and flooring. Look in the room below, too.
- Start drying. Run fans and a dehumidifier. The EPA says to dry water-damaged areas and items within 24-48 hours to prevent mold growth.
- Keep the failed part. Save the burst hose or failed fitting. Your insurer or a plumber may want to see it.
- Keep receipts. Fans, dehumidifiers, a plumber's visit, and emergency services all count.
Is appliance water clean or dirty?
It depends on the appliance. Water from a supply line or a water heater starts out clean. Drain water from a washing machine or dishwasher is dirtier, and is often treated as grey water. Our guide to clean, grey, and black water explains how that changes cleanup.
Clean water does not stay clean forever. Water that sits in a warm basement in August, soaking into carpet and drywall, gets worse with time. One more reason to move fast.
Water heater warning signs
Rheem, a major water heater maker, says traditional tank water heaters typically last 8 to 12 years. It lists water leaking from the base of the tank, rusty or discolored hot water, and rumbling or popping sounds as signs a unit should be replaced.
Rheem also says that if the leak is from the tank itself, replacement is usually required. Small valve or fitting leaks may be repairable. A licensed plumber can tell you which you have.
To find your water heater's age, look at the label. Rheem notes the manufacture date is often encoded in the serial number.
Does insurance cover an appliance leak?
Usually the answer has two parts: the water damage, and the appliance.
The water damage. Sudden, accidental water from plumbing or a household appliance is often covered. In the standard homeowners form, damage from water that escapes a plumbing system or household appliance can be covered, including the cost to tear out part of the house when that is needed to repair the system.
The appliance. The same form says, "We do not cover loss to the system or appliance from which this water or steam escaped" (sample HO-3 policy, Insurance Information Institute). It also excludes "wear and tear, marring, deterioration" and "mechanical breakdown." So the policy may pay to dry and repair your floor and walls, while you pay for the new water heater.
Slow leaks. A drip that went on for months behind the fridge is treated differently from a hose that burst this morning. Gradual damage is often excluded.
Sump pumps are different. The standard form says a plumbing system or household appliance does not include a sump or sump pump. Sump overflow usually needs a backup endorsement. See our guide to sewer backup insurance in Ohio.
Your policy also expects you to limit the damage. The standard form says you must "make reasonable and necessary repairs to protect the property" and keep an accurate record of what you spent. Report the claim promptly. Our Ohio insurance claims guide covers the steps.
How to prevent the next leak
- Replace washer hoses on schedule. Whirlpool recommends replacing washing machine inlet hoses every 5 years to reduce the risk of hose failure and leaks.
- Maintain the water heater. Rheem recommends flushing the tank once a year and replacing the anode rod every 3 to 4 years.
- Put a drain pan under the water heater. If it drains to a floor drain, a small leak has somewhere to go.
- Add leak sensors. Inexpensive water alarms under the water heater, washer, dishwasher, and sink can warn you early.
- Know your shutoffs. Tag the main valve and appliance valves so anyone in the house can find them.
- Turn off the washer valves before a trip. It takes ten seconds.

FAQ
My water heater is leaking from the top. Is it the tank?
Not always. Leaks at the top often come from the pipe connections or a valve, which may be repairable. Leaks from the bottom of the tank more often mean the tank has failed. Have a plumber check it.
Water is coming from the pipe on the side of my water heater. What is that?
That is usually the temperature and pressure relief valve discharge pipe. It is a safety device. Do not cap or plug it. Call a plumber to find out why it is releasing water.
Will my insurance pay for a new water heater?
Usually not under a standard homeowners policy, which excludes the appliance the water came from. The water damage it caused may be covered. Ask your agent.
Do I need to replace flooring after a dishwasher leak?
Not always. If you caught it early and the subfloor dries fully, some flooring can stay. Laminate and engineered wood often swell and need replacing. A moisture check under the flooring tells you more than looking at the top.
