Reduce indoor water use by 30% and save 15,000 gallons a year with the HydroRight. Invented by a plumber, the HydroRight quickly and easily converts your toilet into a water- and money-saving Dual Flush toilet. It works with all standard flush valves and you can install it without tools in 5-10 minutes. Just remove the old flapper and handle and slide over the existing flush valve. The button replaces the handle. Push the quick-flush setting for liquids and paper and the full-flush setting for solids. Look for the HydroRight at The Home Depot and other retailers or visit SaveMyToilet.com [1].
