Next by Danco HYR451T HydroRight Dual Flush Toilet Repair Kit – Water-Saving, Easy Install

Upgrade your toilet with a water-saving, leak-resistant repair kit

The HYR451T HydroRight Total Repair Kit by Next by Danco reimagines a standard toilet’s efficiency. By adding a Dual Flush Converter, this kit could reduce water use on liquid and paper flushes while preserving full volume for solids. The converter sits vertically on the flush valve, creating a reliable seal that minimizes the chance of leaks. Say goodbye to stubborn leaks, tangled flapper chains, and finicky handles that require frequent fiddling.

Designed for real-world use, the HYR451T emphasizes a quick, tool-free upgrade. In about five to ten minutes, you can drop the unit into place without removing the tank. The system offers an adjustable height to fit most toilets (11"–13.8"), reducing the need for additional parts or modifications. The Quick Flush setting delivers a lower water volume for liquids and paper most of the time, while the Full Flush setting restores the standard volume for solids when needed.

Key components are built for durability and reliability. The permafit silicone seal is chlorine- and chemical-resistant, helping maintain a strong seal over time. This Total Repair kit also includes leak-detection features and can be calibrated to fine-tune the exact amount of water used, aligning with different household needs and water-saving goals.

What to expect after installation? A streamlined, dual-flush experience that may reduce water waste while keeping flush performance consistent. The kit is designed for standard 2-inch flush valves and is straightforward to install, with practical tips that aim to minimize disruption to your routine and maximize peace of mind. Note that Mansfield toilets are not compatible with this model.

In short, the HYR451T could help you convert a conventional toilet into a more flexible, water-conscious system—offering choices for everyday use and an eye toward efficiency, without promising specific results for every home.
