The Knapp Supply Co, Inc. is a wholesale distributor of Plumbing Supplies, Industrial Supplies, Kitchen Cabinets, Bathroom Cabinets to professional tradesmen, contractors, and home centers. In continuous business since 1874, Knapp Supply has a strong tradition of leadership in the plumbing and building trades industry for eastern Indiana and western Ohio.

Alexander Knapp founded his china and terrra cotta pipe business on the border of Ohio and Indiana in Union City. Since that time when indoor plumbing was in its infancy and the gas-boom days was industrializing the area, Knapp Supply has carried on Alexander’s vision of providing the best quality material and merchandise at the most affordable price.

Much like our store, you will find our website divided into three sections: plumbing supplies, industrial supplies, and those plumbing and cabinetry items found in kitchens and bathrooms including kitchen cabinets and bathroom cabinets.
