Metropolitan Property and Casualty Insurance Company as subrogee of Alex Kogan v. Pentair Residential Filtration, LLC, and Arista Air Conditioning Corp.
Attorneys and Parties
Brief Summary
Products liability for a residential water filter used in a humidification system; foreseeability of non-typical use; manufacturing and design defect theories; limits on raising failure-to-warn at summary judgment.
Denied Pentair’s motion for summary judgment on the products liability claims.
References to a strict liability failure-to-warn theory were stricken; the remainder of the order denying summary judgment was affirmed.
Failure-to-warn was raised for the first time in opposition to summary judgment (see Ostrov v Rozbruch, 91 AD3d 147, 154 [1st Dept 2012]); issues of fact remained on foreseeability, possible manufacturing defect given the pressure specification, and design defect based on a feasible more robust alternative.
Background
Alex Kogan purchased a Pentair water filter and installed it in an apartment humidification system. The filter allegedly failed, causing over $1 million in water damage. Metropolitan Property and Casualty Insurance Company (MetLife) paid the loss, became subrogated to Kogan’s rights, and sued Pentair alleging the filter was defective. Pentair moved for summary judgment, arguing the use was unforeseeable and that no manufacturing or design defects existed.
Lower Court Decision
The Supreme Court, New York County, denied Pentair’s summary judgment motion, allowing products liability claims to proceed.
Appellate Division Reversal
Modified to strike any failure-to-warn theory because it was raised for the first time in opposition to the motion; otherwise affirmed. The court found triable issues of fact on foreseeability (conflicting expert opinions on using the filter in a humidification system), manufacturing defect (unit rated for 30–125 PSI while site pressure was 110 PSI, suggesting a unit-specific defect could have caused failure), and design defect (Pentair’s expert acknowledged a feasible more robust alternative design).
Legal Significance
The decision underscores that foreseeability of a product’s use beyond its typical application is often a fact question supported or refuted by expert testimony; admissions regarding feasible safer designs can create triable issues on design defect; and a plaintiff cannot inject a new failure-to-warn theory for the first time in opposition to summary judgment.
On products liability summary judgment, defendants face denial where plaintiffs present expert evidence on foreseeability, potential manufacturing defects within stated pressure limits, and feasible safer designs; however, failure-to-warn claims must be pleaded timely and cannot be raised for the first time in opposition papers.
