About Plumbers Supply CO.
Plumbers Supply CO., a for-profit Subchapter S corporation headquartered in Louisville, Kentucky, supplies plumbing fixtures, heating equipment, sprinkler components, and related supplies to federal agencies as a prime contractor under full-and-open competition, with no set-aside designations across its federal footprint. The vendor operates as a pure supplier — 100% of its 175 federal awards are prime purchase orders, with no subcontract or grant-recipient activity.
The vendor's capability portfolio centers on plumbing and heating equipment distribution. Recent awards include a $112,244.70 firm-fixed-price purchase order from the Federal Correctional Institution Berlin for water heater replacements at a secure housing unit (May 2026), a $32,540.00 emergency replacement order from the Federal Correctional Complex Terre Haute for water heaters in support of Project 24Z4AU8 (July 2025), and a $39,407.96 order from the US Census Bureau for fire suppression sprinkler system repair parts to support the National Processing Center in Watson, Indiana (November 2023 through March 2024). Top NAICS categories reflect equipment distribution and light manufacturing: Plumbing and Heating Equipment and Supplies Merchant Wholesalers (16 awards), Plastics Plumbing Fixture Manufacturing (5 awards), and Other Metal Valve and Pipe Fitting Manufacturing (3 awards). Top PSC codes align with product supply — Plumbing Fixtures and Accessories (99 awards), Miscellaneous Construction Materials (15 awards), and Valves, Nonpowered (14 awards).
Customer concentration is dispersed across twelve distinct federal agencies, with the top five agencies accounting for only 15% of award count. The Department of Veterans Affairs Veterans Health Administration Veterans Integrated Service Network 9 leads by potential value at $139 thousand across six awards, followed by the Federal Correctional Institution Berlin with $112 thousand from a single large order. The Department of the Army Installation Management Command Southeast Region contributes $92 thousand across eight awards, and the Census Bureau contributes $53 thousand. Activity has been episodic — one award in 2025, one in 2026, and sparse prior years — with combined potential value of $667 thousand across the entire twenty-four-year award history and near-parity between potential value and actual obligations ($671 thousand obligated).
