A newly constructed house was flooded when a plumbing pipe ruptured in the attic during unusually cold weather well below the freezing point. This was a very large house and had been constructed with the most visually appealing and expensive finish materials in the construction industry.
Out of sight of the homeowners was a section of plumbing piping in the attic. This piping had been routed without any insulation and had frozen and ruptured, resulting in a large leak when the freezing temperatures subsided. Unfortunately, the homeowners were away for the holidays when this occurred. The leaking water flooded all three stories of the house and resulted in substantial damage repairs that far exceeded the minor cost to have properly insulated the piping section to begin with.
Modern building codes have required for the past decades that plumbing piping in unheated areas such as attics or crawlspaces be insulated to prevent freezing and rupture. However, in normally warm climates, such as the Southeastern United States, these requirements are often not followed by general contractors and plumbers and are sometimes not found during building and pre-purchase inspections. The failure to properly insulate the plumbing piping in this case was found to be a condition of defect in the construction of the house due to the improper work of the general contractor and plumbing company.
The homeowner’s insurance company was able to successfully subrogate this loss against the general contractor and plumber’s insurance companies.
