Water has a remarkable ability to find the weakest path into a building. Insurance companies have an equally remarkable ability to find every exclusion that might apply after it gets there.
Tinkelman v. Liberty Mutual Insurance Company 1 involved a Pennsylvania homeowner who discovered approximately four and a half feet of water in his basement. He had installed two sump pumps specifically for redundancy. Both pumps were operating. The apparent mechanical problem was not the pumps, but an underground discharge pipe that had become compressed from approximately two inches in diameter to about one inch.
The restricted pipe could not carry away enough water. The sump system was overwhelmed, and the basement flooded. The resulting damage allegedly exceeded $100,000.
Safeco denied the claim only four days after the loss, without sending anyone to inspect the property. Its denial relied upon the policy’s water-damage exclusions. The policyholder argued that the loss resulted from an obstruction or malfunction of a drain on the residence premises, which is an event specifically excepted from one portion of the water-damage exclusion.
I thought the argument had an intuitive appeal. The pumps worked. The pipe failed. If the policy provides an exception for an obstructed or malfunctioning drain on the premises, why should the loss not be covered?
The answer was found in another exclusion. The policy separately excluded water that “escapes or overflows or discharges, for any reason,” from a sump pump, sump-pump well, or any other system designed to remove water from the foundation area.
The words “for any reason” were killers. They meant the exclusion didn’t depend upon whether the pump failed, lost power, became clogged, or continued operating perfectly. The crushed discharge pipe may have explained why the system was overwhelmed, but the exclusion said that the reason did not matter. Water overflowed from a system designed to remove foundation water, and that was enough for the court.
The policy also excluded groundwater and contained anti-concurrent-causation language stating that a loss remained excluded regardless of another cause or event contributing concurrently or in sequence. Safeco thus had three routes out: the groundwater exclusion, the sump-system exclusion, and the anti-concurrent-causation clause.
The policyholder’s principal mistake was treating an exception to one exclusion as though it were an affirmative grant of coverage. It was not. Even if the crushed pipe satisfied the exception concerning an obstructed drain, the loss still had to survive the separate sump-system and groundwater exclusions.
The court granted summary judgment to Safeco on both breach of contract and bad faith. The court’s analysis of whether the discharge pipe was a “drain” was too abbreviated, and its reliance on somewhat uncertain groundwater testimony was questionable. But the broad sump-system exclusion probably carried the day on its own.
Safeco’s claim investigation deserves no gold star. Denying a six-figure water loss within four days without inspecting the property is hardly a model of careful adjustment. Nevertheless, a poor investigation does not automatically create coverage where the policy excludes the loss. Once the court found Safeco’s coverage position correct, the policyholder’s largely undeveloped bad-faith claim fell with it.
This is a federal district court decision applying Pennsylvania law and not a sweeping ruling from the Pennsylvania Supreme Court. Its broader lessons nevertheless apply to water-loss claims everywhere.
1. Read the entire policy before deciding what caused the claim.
Public adjusters and policyholders should obtain the complete policy, including every endorsement. Do not stop after finding one promising provision. Determine whether the policy includes water-backup or sump-overflow coverage, identify any separate limit, and then review every exclusion that might independently apply.
2. Map the entire journey of the water.
Coverage may depend upon where the water originated, what conveyed it, where it escaped, and how it entered the building. The broken component is only one part of that chain. A crushed pipe may be the mechanical cause, but groundwater entering through a sump well may still be the excluded pathway.
3. Never overlook “for any reason.”
Those three words can make the precise cause of a failure legally irrelevant. When a policy excludes water escaping from a sump system “for any reason,” proving that the pump itself worked may accomplish very little. Public adjusters should highlight this language during the initial coverage review rather than discovering its impact after depositions have been taken.
4. An exception to an exclusion does not create coverage.
An exception merely limits the particular exclusion in which it appears. The claim must still survive every other exclusion. Finding an exception is the beginning of the analysis, not the victory lap.
5. Preserve the physical evidence before it disappears underground.
Photograph and video the sump pit, pumps, check valves, discharge piping, standing water, and high-water marks. Preserve removed pipe sections. Obtain and retain camera footage from plumbers and drain-cleaning companies. Once the trench is filled and the damaged pipe is discarded, the best evidence may be gone with the water.
6. Use a qualified causation expert when the pathway matters.
A contractor may know what was repaired but still be unable to determine the water’s origin, measure pump capacity, calculate flow restriction, or explain whether water entered through the sump system or another source. A plumber, engineer, or hydrologist should test and document those issues before opinions harden into “undisputed facts.”
7. Describe facts carefully and build bad faith separately.
Words such as “groundwater,” “flood,” “sump backup,” and “storm water” carry coverage consequences. Report what was observed before announcing a legal conclusion about what happened. If bad faith is alleged, develop evidence about the insurer’s investigation, claim notes, internal standards, coverage research, and knowledge at the time of denial. “They disagreed with me” is not a bad-faith case.
The sump pumps in Tinkelman apparently did exactly what they were supposed to do. Unfortunately for the policyholder, the exclusion also did exactly what Safeco wrote it to do.
That is the uncomfortable lesson: sometimes the pump works, the pipe fails, the basement floods—and the most consequential failure occurred years earlier, when nobody noticed that the policy excluded water from the entire sump system “for any reason.”
