Trumbull Industries was founded in 1922 in Warren (Trumbull County), Ohio. The Waterworks Manufacturing Division was formed in 1981 to offer specialty products for the Municipal and Industrial markets. Product categories include Valve Position Indicators, Tools, Polywrap, Joint Restraints, Meter Box Lids and Couplings, Valve and Curb Box Accessories as well as Valves and Accessories for Water/Wastewater Treatment Plants.

We specialize in unique and customized accessories for the valve market. We have pioneered cast stainless valve accessories such as stainless chainwheels, floorstands, wall brackets and stem guides. Other innovations include our valve position indicators and cast stainless mud valves that have been thoughtfully designed to meet the highest expectations of Engineers and Operators

In 1990, Trumbull purchased the Ludlow and Corey-Rensselaer hydrant product line. That acquisition expanded Trumbull’s manufacturing capabilities and expertise in making repair parts for obsolete fire hydrants.

We stand behind our product with experienced Engineering, Quality Control and Field Service personnel. Our products are designed for long life, and are rigorously tested, in-house and at independent labs. Our inside sales staff is passionate about customer satisfaction.

Today, the product line is sold to Waterworks distributors, valve representatives and manufacturers both nationally and internationally. Our primary inventory is maintained in Warren, Ohio with Rep warehouses in Orlando, Phoenix, Los Angeles, Atlanta, Dallas and Seattle.
