Coyne & Delany Company was founded in 1879 by John J. Delany and Thomas Coyne. They were part of that first generation of lrish that arrived in America looking to escape the Potato Famine of Ireland and find a new life and opportunity in the new world. In those days, the family business was centered on the production of copper-lined wooden tubes and wooden overhead tanks for water closets. By the turn of the century, the product line had expanded to include cast iron tubs, brass plumbers trim,wooden flush tanks and fittings and ballcocks.

Then in 1910 Tom Coyne suddenly died. Leaving no male heirs to assume his stock or role in the company, his wife chose to sell his shares to John Delany. Over a 130 years later and now into its fourth generation, the company is still 100% family owned. The Company has seen many changes along the way starting with the introduction of its first flush valve, the Flushboy, in 1927, which changed the product line forever.

Having survived the Great Depression, World War II took the Company from being a regional power in the Northeast to being a national company by selling to military bases throughout the U.S. During the late 40s, 50s, and into the 60s, John J “Doc” Delany pioneer numerous patented products. In 1943, he patented and introduced the first ever rubber sleeve Vacuum Breaker to the market. Then in 1948, Doc invented and patented the hallmark feature of all Delany flush valves, the Regulating Screw, allowing a valve to be externally adjusted in the field. In 1956, Doc patented another trademark feature of the Delany valves, the Rubberflex handle. This is still the only non-spring loaded handle on the market today.
