The video from the manufacturer above uses an eight year-old kid to emphasize how easy to install the kit. All you really need to do is turn off the water using the valve behind the tank, remove the flapper and toilet handle, replace those with the new ones from the HydroRight kit, and turn the water back on.

The manufacturer claims that most users will recoup the cost of the retrofit kit within two months of water bills and that within a year you'll save enough water to fill a swimming pool.
