Standard homeowners policies exclude flood, which in insurance means rising water from outside — rivers, storm surge, surface runoff. Flood is covered separately through the National Flood Insurance Program or a private flood policy. A pipe that bursts inside your house is not flood, and that internal water damage is generally covered. NFIP building limit $250,000 NFIP contents limit $100,000 Waiting period 30 days Burst pipe is flood? No ## The short version - "Flood" in a policy is a technical term meaning water arriving from outside and rising. It is not a synonym for "a lot of water". - Internal water — a supply line, a water heater, an appliance hose — is a different peril and is generally covered. - NFIP policies have their own limits, their own deductibles and a waiting period before coverage starts. - Where the water came from decides the coverage question before anything else does. ## The word does not mean what people use it to mean # Link to this section In ordinary speech, “ flood ” means a lot of water somewhere it should not be. In an insurance policy it is a defined term with a narrow meaning: water arriving from outside the building and rising — rivers and streams leaving their banks, storm surge, surface runoff, mudflow. That gap between the everyday word and the policy word is where a great deal of avoidable confusion lives, and it is the reason a homeowner with a burst supply line sometimes believes they have no coverage when they do. ## Where the water came from, in order of how it is usually treated # Link to this section Where the water came from Usually treated as Usually covered by Supply line, water heater, appliance hose Sudden and accidental internal water Homeowners policy Rain through an opening the storm created Wind-driven rain Homeowners policy River, storm surge, surface runoff, mudflow Flood NFIP or private flood Sewer or drain backup Backup Often an endorsement, not automatic Long-term seepage or a leak left unrepaired Gradual damage Usually excluded The last row is worth reading twice. Policies generally cover losses that are sudden and accidental. Damage that developed slowly over months, from a leak that was there to be found, is treated very differently from a pipe that failed on Tuesday. ## The NFIP definition, in full # Link to this section This is the actual definition, and the detail most summaries drop is in the first line: A general and temporary condition of partial or complete inundation of two or more acres of normally dry land area or of two or more properties (at least one of which is your property) from: - Overflow of inland or tidal waters - Unusual and rapid accumulation or runoff of surface waters from any source - Mudflow - Collapse or subsidence of land along the shore of a lake or similar body of water as a result of erosion or undermining caused by waves or currents of water exceeding anticipated cyclical levels Read that first line again. A flood, for NFIP purposes, has to affect two or more acres or two or more properties. Water that entered only your house, from a source inside it, does not meet the definition — which is the technical reason a burst pipe is not “flood” no matter how much water there was. ## NFIP limits and the waiting period # Link to this section Building coverage up to $250,000 Contents coverage up to $100,000 Waiting period 30 days from purchase Contents are not automatic — they are bought separately from building coverage. If the limits are below what your home would cost to rebuild , excess flood coverage is a separate private product. The 30-day waiting period has four exceptions , and they are worth knowing because they are the only ways to have coverage sooner: - Buying while making, increasing, extending or renewing a mortgage — no wait. - Changing coverage at policy renewal — no wait. - Property newly designated in a high-risk flood zone, bought within 12 months of the map update — one day. - Flooding caused or worsened by wildfire on federal land, bought within 60 days of containment — one day. Outside those, buying as a storm approaches does not work. That is the point of the waiting period. Verify current limits and terms with FEMA before relying on them. Program terms change. ## What this means for your claim The first question anyone should ask about a water loss is not how bad it is. It is where the water came from , because that single fact routes the claim to an entirely different policy. Water that entered from outside and rose is flood. Water that escaped from a system inside the building is not. A roof opened by wind that then let rain in is a third situation again, and is usually handled as wind-driven rain under the homeowners policy rather than as flood. This is also where the most common denial comes from. A claim filed under the wrong peril, or described loosely in the first phone call, can be routed to an exclusion that never actually applied. This depends on your state Insurance regulation, assignment-of-benefits rules, mold and biohazard requirements, and licensing are all set by state. This page reflects FEMA / NFIP published program materials as of 2026-08-21. Verify with your state department of insurance before you rely on it. ## Common mistakes - Describing a burst pipe as "my house flooded" on the first call, which is how an internal water loss gets looked at under a flood exclusion. - Assuming an NFIP policy pays the same way a homeowners policy does — the limits, deductibles and contents treatment are different. - Buying flood coverage during a storm watch and expecting it to apply, without accounting for the waiting period. - Assuming a basement is covered the same way as the rest of the house under NFIP. It is not treated identically. ## Common follow-up questions ### Is a burst pipe considered a flood? No. In insurance terms flood means water arriving from outside and rising. A pipe failing inside the building is internal water damage, a different peril, and generally covered under a standard homeowners policy. ### Does NFIP cover my basement? NFIP treats basements and areas below the lowest elevated floor differently from the rest of the dwelling, with narrower coverage. Check the current program terms before assuming a basement is covered the same way. ## Related questions - The first hour after a water loss - Water categories 1, 2 and 3 - Mold coverage is capped — here is roughly where - Additional living expense - What an assignment of benefits does ## Sources Every source cited on this page - T1 The National Flood Insurance Program — FEMA (accessed 2026-08-21) - T1 Flood Insurance — FEMA (accessed 2026-08-21) - T2 Homeowners insurance basics — Insurance Information Institute (accessed 2026-08-21) Written by: PLACEHOLDER — Claims Reviewer Reviewed by: PLACEHOLDER — Claims Reviewer Last reviewed: 2026-08-21 This page is general information, not insurance, legal or medical advice.
