Plumbing and Industrial Supply Company was founded in 1968 in Whittier, California. Almost 50 years later, the company still maintains its corporate headquarters in Los Angeles, California, and continues to offer the same professional, friendly, and service-oriented business our customers have come to expect. Plumbing and Industrial has evolved over the years to a wholesale plumbing supply company offering products for both commercial and residential applications specializing in pipe, valves and fittings.
