The Burst Pipe, the Mold, and the Slow Drip
An HO-3 in Spokane covers a 1998 house for $420,000 (Coverage A) with a $2,500 deductible. The form carries a $10,000 mold sublimit and ordinance-or-law coverage limited to 10% of Coverage A. While the owners are away for three weeks, the second-floor supply line to a toilet bursts. Water runs through the ceiling: $46,000 to dry, repair, and replace ruined drywall, flooring, and a vanity. The contractor then finds $11,000 of mold behind the kitchen wall and $8,000 of rot under the powder-room sink, caused by a supply fitting that had been seeping for months. The city also requires $9,000 of code upgrades during the rebuild.
1. Allocate each item to coverage or exclusion, and state how many deductibles apply and why.

Burst supply line - covered, $46,000. Sudden and accidental discharge from a plumbing system is the classic covered water peril. The HO-3 is open-peril on the dwelling, so the carrier must find an exclusion; none fits a pipe that failed without warning while the house was occupied by nobody but still heated.
Mold behind the kitchen wall - covered but sublimited, $10,000 of $11,000. Mold is not a named peril, but it is covered as resulting loss from a covered water event. The sublimit is a hard cap, so $1,000 is the owner's.
Powder-room rot - excluded, $0. Constant or repeated leakage over weeks, plus rot and deterioration, falls squarely within the seepage and wear-and-tear exclusions. Nothing here is sudden. Because the loss is excluded, no deductible is consumed by it.
Code upgrades - covered, $9,000, within the $42,000 limit. 10% of $420,000 is $42,000, so the limit is not the issue.
Deductibles: one. The burst line and the mold it produced are one occurrence, so $2,500 is applied once. The seepage is a separate event in theory, but an excluded one, so it does not generate a second deductible.
2. Compute the likely settlement and identify what the owners absorb out of pocket. Where might the adjuster legitimately trim the code-upgrade payment?

Settlement:
- Water damage: $46,000
- Mold: $10,000 (sublimit)
- Ordinance or law: $9,000
- Subtotal: $65,000
- Less one $2,500 deductible: $62,500
Out of pocket: $1,000 (mold above the sublimit) + $8,000 (excluded seepage and rot) + $2,500 (deductible) = $11,500 of a $74,000 total.
Where the code payment can be trimmed. Ordinance-or-law coverage is written to pay the increased cost of repairing the damaged portion to comply with current code, not to bring undamaged parts of the house up to code. If the city's demand covers arc-fault breakers for the whole panel and an egress window in an untouched bedroom, only the portion tied to the repaired area is payable, and the adjuster should ask the inspector to break the requirement into damaged-area and voluntary-upgrade components. That is a coverage argument, not a negotiation.
3. The insured insists the powder-room fitting 'just started leaking.' What should the adjuster ask before closing the file?
Read the worked answer
The insured's label does not decide the exclusion; the timeline does.
- When did the seepage begin? Staining, a soft cabinet floor, or a swollen toe kick usually predates discovery by far more than 14 days. Photograph and date everything.
- Maintenance and repair history. Any prior plumber visit, prior staining complaint, or DIY tightening matters.
- The plumber's failure analysis. A corrosion pinhole that developed over months reads differently from a fitting that cracked last Tuesday. Ask for the removed part.
- Are the two events connected? If the powder-room fitting failed because of pressure from the same shutoff work, the insured will argue one occurrence, which changes the deductible and may pull the rot inside the covered event. The carrier will argue independent causes.
- Occupancy facts. Who checked the house, was the heat on, was water shut off. A freeze explanation would move the analysis back toward a covered sudden event.
If the evidence is genuinely ambiguous, document the ambiguity in the file rather than resolving it unilaterally; a $8,000 denial is worth a second look before it becomes a bad-faith allegation.
