The chain connecting the toilet handle to the flapper is broken, I set out to Canadian Tire to buy a replacement chain. Instead of buying a $2 little chain, I end up buying the HydroRigth Dual-Flush system to retrofit my ordinarily toilet to a dual flush toilet. A dual flush toilet save water by adjusting the water flow depending on your needs. You don’t need a full tank of water if there is only pee in the toilet.

The installation is really easy. As the box claim, no tool is required. Just take out the old drop handle and flapper, drop in the new flush system and you are done. The box claims it can be installed in 10 minutes, but it took me almost 30 minutes to adjust the optimal water level for half flush and full flush. The mechanics of the dual-flush system is pretty smart. The full flush operation is pretty much the same as lifting up an old fashion flapper. The trick is on the half flush operation. It has an internal adjustable buoyant control for the half flush operation, when the water level drops below the buoyant, it will close the flapper automatically.

The dual flush system saves half tank of water for every half flush, that adds up to lots of water saving over a year. With the new dual flush toilet installed, I am proud of having a green and environmental friendly life style by using water more efficiently..
