The Delany Difference Simplicity in Design

The TruStop is a patented innovation poised to reduce the cost of maintenance for institutional water closets, toilets and urinals.

The Problem

Control stops in flush valves will fail over time. With traditional flush valves, replacing the Control Stop requires turning off the water to the bathroom, a hall or floor, sometimes the entire building.

This is inconvenient and costly.

Fixing a control stop can be very challenging in these old buildings. We often have to shut down the water to a riser line, affecting multiple floors. This requires the work to be done at night or on weekends. Sometimes we have to call in DOE plumbers which makes what should be a simple fix into very expensive and time consuming project.

The Solution

The Delany TruStop with patented ball valve design fits right to the flush valve which allows for easy water shutoff at the stop in order to replace the failed backcheck.

  1. Vandal proof and a simple ¼ turn for shutoff
  2. Ball valve design that will last for decades
  3. Retrofits with all leading flush valve brands

Saves Time And Money

This patented breakthrough in commercial flush valve technology ends the need for costly after hours repairs.

One person can do the job in minutes — not hours.

Delany's Rubberflex Handle Assembly provides a leak free seal that lasts and is easy for owners to repair at a fraction of the cost of competitors' handles. It is also both ADA compliant as well as chloramine resistant.

“The Chesterfield County School System is the third largest public county school system in the state of Virginia. We have been using Delany Products (previously Coyne & Delany) flush valves for almost 60 years. As head of the county’s maintenance department for 35 of those 40 some years, I personally have a lot of experience with these products. the Delany flush valves are one of only two valves that we will allow in any of schools’ buildings.”
