Back in 1921, Sam Blackman opened a small plumbing supply shop in Brooklyn with the promise of offering the best products for the best prices, with a firm commitment to the trade. Today, Blackman has grown into one of the nation's largest family-owned and managed suppliers of plumbing, heating, industrial, waterworks and HVAC equipment. With 22 fully-stocked branches and showrooms located throughout the metropolitan New York area, Blackman has become a convenient, reliable resource for today's building and remodeling professionals.
