Keller Supply's 50+ branches are located throughout 8 states, with headquarters in Seattle, Washington.   We've long been recognized as the leader in the Pacific Northwest residential plumbing supply market, both in new construction, as well as repair and remodeling.   We took what we learned in the residential market and built upon that success. Keller Supply is continually embarking on a plan of significant growth in new markets, both geographically and through product diversification.   With several branches specializing in commercial plumbing supplies and industrial pipe, valves and fittings, mechanical contractors now rely on Keller Supply to meet their commercial and industrial needs, just as residential plumbing contractors have for years.   We were recently ranked the nation's 23rd largest plumbing supply wholesaler and the 34th largest privately company in Washington State
