Ferguson Enterprises is part of the pipeline for pipes. The US's largest wholesale distributor of plumbing supplies, the firm offers pipes and valves, faucets and fixtures, and heating and air-conditioning parts, as well as waterworks products (such as water hydrants and meters), safety equipment, and tools. It has more than 700 locations throughout the US and in Barbados, Columbia, Mexico, and Trinidad. Ferguson's customers include plumbers, kitchen and bath dealers, municipalities, and manufacturers. Ferguson, which was formed in 1953, is growing through acquisitions. Wolseley, the world's #1 plumbing and heating equipment distributor, bought Ferguson in 1982 and combined it with subsidiary Familian in 1998.
