Serving Professional Tradesman, Contractors, Remodelers, & Homeowners Since 1874
Knapp Supply has been serving professional tradesman, contractors, remodelers and homeowners for over 140 years. Knapp Supply has a strong tradition of leadership in the plumbing and building trades industry for all of Indiana, Western Ohio and Northern Kentucky.
In an era before reality TV and pizza delivery at the click of a button, Alexander Knapp founded his china and terra 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 were industrializing the area, Knapp Supply has carried on Alexander’s vision of providing the best quality material and merchandise at the most affordable price.
