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, and 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. - NYC School Building Engineer  

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 back check. 

Vandal proof and a simple ¼ turn for shutoff

Ball valve design that will last for decades
