Short answer: Delaware's insurance department lists burst washing-machine hoses among the costliest home water claims, along with refrigerator and hot-water-tank leaks, and notes rubber hoses eventually fail — often in a low-traffic laundry room where damage goes unnoticed (Delaware DOI). EPA WaterSense tells homeowners to check for pooling water at the clothes washer (a supply-line leak clue) and flags washing-machine hose failure as a classic catastrophic leak that automatic shut-off devices can stop (EPA; EPA). Charleston, WV's sanitary board advises replacing washing-machine hoses every three to five years (Charleston Sanitary Board). A sudden and accidental discharge is often covered for resulting damage; gradual leaks, wear-and-tear of the hose itself, and most mold cleanup usually are not (Texas Department of Insurance; NAIC).
This guide applies in all 50 states. It is based on Delaware Department of Insurance consumer alerts, EPA WaterSense leak-detection guidance, a municipal utility prevention page, and NAIC / Texas Department of Insurance homeowners guidance, checked in October 2026.

Why washing-machine hoses punch above their weight
A washing machine sits on pressurized supply lines that can run for hours while you are at work or asleep. Delaware's Department of Insurance warns that rubber hoses on many washers eventually leak, that laundry rooms are often low-traffic, and that water into carpet, walls or other absorbent materials can become a catastrophic problem — including mold follow-on (Delaware DOI). The same alert groups burst washing-machine hoses with refrigerator water-supply line leaks and hot-water-tank leaks as among the costliest water claims (Delaware DOI).
EPA's WaterSense "Detect and Chase Down Leaks" checklist specifically tells you to inspect the clothes washer for pooling water that could mean a supply-line leak, and to check dishwashers and refrigerators with ice makers the same way (EPA). EPA's later leak-detection / flow-monitoring guide names washing machine hose failure alongside failed water heaters and pipe bursts as the kind of catastrophic leak where a device with an automatic shut-off valve can stop the water before the house floods (EPA). That guide cites industry claim data that from 2019 to 2023, 1.5% of homeowners submitted a water-damage or freezing claim with an average cost of $15,400 — higher than the typical cost to buy and install a shut-off-capable leak detector (EPA).
Prevention checklist (official sources)
| Step | Source |
|---|---|
| Replace washing-machine hoses every 3–5 years | Charleston Sanitary Board |
| Prefer steel-encased hoses over plain rubber (Delaware notes steel-encased hoses remove the need to swap rubber every three years) | Delaware DOI |
| Look for pooling water at the washer, dishwasher and fridge ice-maker line | EPA |
| Check sink, ice-maker and dishwasher lines for wear or deterioration | Charleston Sanitary Board |
| Consider an automatic water shut-off or leak-detection device, and place moisture sensors behind the washer | EPA; Charleston Sanitary Board |
| Know how to shut the house water off; turn supply valves off for weekend getaways when practical | Delaware DOI |
| Recaulk tubs yearly; watch toilet base moisture and water-heater rust / drip pans | Delaware DOI; Charleston Sanitary Board |
Turn the washer supply valves off when you leave for more than a day if your valves are easy to reach. A failed hose with the valves open can empty a large volume of water onto the floor.
What homeowners insurance usually covers
Standard homeowners policies are built around named perils. Texas's consumer guide lists sudden and accidental release of water or smoke as a covered peril on common policy forms, and separately warns that a continuous water leak is not covered, and that policies usually will not cover mold removal except as needed to repair damage from a covered risk (Texas Department of Insurance). The NAIC's homeowners guide likewise frames coverage around listed perils (fire, theft, windstorm and similar) and reminds consumers that a homeowners policy is not a maintenance contract (NAIC).
Typically covered (when sudden and accidental):
- Resulting water damage to floors, walls, ceilings, cabinets and personal property from a hose that bursts
- Tear-out to reach the failed line, on many policies
- Additional living expenses / loss of use if the home becomes unlivable (NAIC)
Your deductible applies.
Typically not covered:
- The worn rubber hose or corroded fitting itself (wear and tear / maintenance)
- Slow seepage over weeks that you could have noticed
- Mold remediation beyond limited repair of covered sudden damage (Texas Department of Insurance)
- Flood water that enters from outside — that needs a separate flood policy (Delaware DOI)
- Sewer or drain backup, unless you bought that endorsement — see sewer backup coverage
For mold and water-claim documentation tips, see water damage and mold claims.
After a hose fails: what to do
- Shut the water off at the washer valves or the main shutoff (Delaware DOI).
- Document with photos before major cleanup; move undamaged items out of the wet zone.
- Call your insurer promptly. Ask whether the loss looks like sudden discharge and what your deductible is.
- Dry the structure quickly to limit secondary damage; keep damaged hose sections until the adjuster releases them.
- Replace with steel-encased hoses and consider a shut-off device before you put the washer back in service (Delaware DOI; EPA).
Texas notes that repeated non-weather water claims can affect renewal, with special rules around appliance-related water claims after repairs pass inspection (Texas Department of Insurance). Ask your agent how a laundry-room claim would be counted under your policy and state rules.

Frequently asked questions
Does homeowners insurance cover a burst washing-machine hose?
Resulting sudden water damage is often covered under a sudden-and-accidental water peril; the worn hose itself and gradual leaks usually are not, and mold coverage is limited (Texas Department of Insurance; Delaware DOI; NAIC). Read your policy.
How often should I replace washing-machine hoses?
Charleston Sanitary Board advises every three to five years. Delaware's insurance department recommends steel-encased hoses and notes rubber hoses commonly need replacement about every three years (Charleston Sanitary Board; Delaware DOI).
What does EPA say about clothes-washer leaks?
EPA WaterSense says to check for pooling water at the clothes washer, which can signal a supply-line leak, and lists washing-machine hose failure as a catastrophic leak that automatic shut-off devices can stop (EPA; EPA).
Is a laundry-room flood the same as a flood insurance claim?
No. An internal plumbing or hose failure is a homeowners sudden-water question. Damage from rising outdoor floodwater is usually excluded and needs a separate flood policy (Delaware DOI).
How expensive are water-damage insurance claims?
EPA's leak-detection guide cites data that from 2019 to 2023, 1.5% of homeowners filed a water-damage or freezing claim with an average cost of $15,400 (EPA).
