The company distributes plumbing, heating, and waterworks products to contractors across North America, having moved its primary listing from London to New York in stages through 2024 and 2025. Distribution is a local business won on inventory availability and branch density, since a contractor who cannot get a part today buys elsewhere. Residential repair and remodel activity, not new housing starts, supplies most demand. Scale in purchasing is the durable advantage over regional competitors. Headquarters are in Newport News, Virginia.
