This water-saving dual flush toilet repair kit converts a standard toilet into a water-efficient one. It combines two products: the HYR271 Dual Flush Converter and the HC630 HydroClean fill valve, increasing your toilet's efficiency.

The kit is compatible with standard 2-inch flush valves and requires a 10-inch minimum clearance from the highest point of the flush valve opening to the inside of the tank lid. However, it's not compatible with 1.28 GPF toilets, toilets with 3-inch flush valves, or Mansfield Brand toilets.

When installing, place the Dual Flush Converter directly in the center of your existing flush valve. Also, don't remove the overflow tube and flush valve from the toilet tank; the Dual Flush Converter replaces the existing flapper. Slide the blue silicone dome gasket down the overflow tube and seat it into the flush valve.

This kit eliminates common leaky toilet problems caused by worn-out flappers, handles, or faulty flapper chains. The permafit silicone seal is chlorine and chemical resistant and won't warp.

The dual-flush light-touch button features a unique split handle design. The short center button is the Quick Flush setting, using significantly less water for liquids and paper (needed 4 out of 5 times). The second complete push button at the end is the Full Flush, using the normal amount of water for solids.

The kit detects leaks and signals when a leak is found. It can also be calibrated to adjust the exact amount of water needed, saving water.
