Company History / Overview

For over 90 years, Plumbers Supply Co. has stood proud as the region’s ultimate supply and service source in the plumbing, heating and piping industry. In 1921, John Werst Sr. co-founded the first of what have become five separate divisions, 10 branch offices, and a main warehouse facility boasting 50,000 different products at a value of more then $20,000,000.

With so many divisions and branches, Plumbers Supply Co. has grown to become the preferred source in the region. Plumbers Supply Co. prides itself on continuing what allowed it to grow so successfully; extensive inventories, close customer relationships supported by knowledgeable staff, and quick response times.

Plumbers Supply Co. is organized into five separate divisions; Industrial/PVF, Plumbing, Hydronics/Pump, HVAC, and Fire Protection. Each of our branches maintains an impressive inventory, and has the added advantage of drawing upon the 50,000 plus item inventory of the Louisville location.

Equipped with a massive fleet of trucks at each location, Plumbers Supply Co. can quickly dispatch everything from pick-up trucks to tractor trailers to your jobsite. Deliveries can be arranged for specific times, or in an emergency, one hour deliveries can be made from each branch.

We have personnel on call around the clock, every day of the year, to allow our customers access to our inventory during emergencies. Ask us how you can check your pricing, stock and even place orders 24/7 via a secure Internet Account.


Don’t let our name fool you. Plumber Supply Co. is much more than a plumbing distributor. In fact, we are the area’s most complete, advanced, and experienced supplier of commercial and industrial pipe, valve and fittings. In fact, PSC carries one of the Midwest’s largest inventories of plastic, carbon steel, and stainless steel pipe, valves, and fittings to provide “one stop shopping”. Our valve, and fitting inventory includes PVC, CPVC, carbon steel, stainless steel and forged steel.

For large projects, we will gladly supply jobsite storage trailers outfitted with pipe racks and bins, and fully stocked with an inventory tailored to the project requirements.
