Given the opposing experts' contradictory reports, the court denied both the insured and insurer's motions for summary judgment regarding coverage for a pipe leak. Pronti v. Hanover Ins. Co., 2022 U.S. Dist. LEXIS 222306 (W.D. N. Y. Dec. 9, 2022).

The insured had a swimming poll and spa, which functioned using a subsurface plumbing system, covered with concrete decking. A subsurface pipe began to leak, preventing the pool from properly functioning. The insureds gave notice under their homeowners' policy and contended that significant portions of the pool, spa, concrete decking and other landscaping had to be torn out to do repairs. The insurer retained an expert, Sarah G. Byer, a structural engineer, to investigate. The parties agreed that the pipe had a leak, but disputed if the location of the leak was specifically identified.

The parties also disputed the cause of the leak. Byer found that the most likely cause was deterioration incurred over the pipe's lifetime based on the age of the plumbing system and Byer's personal observation of the pipe. Byer further stated that the physical qualities of flexible PVC piping made it susceptible to damage from chlorine and water over time.
