First came dual flush toilets — a pretty ingenious idea for saving water — then about a year or so ago somebody came up with the idea of a dual flush conversion kit for your existing toilet but priced it so high your grandchildren wouldn’t live long enough to see any payback. Today we noticed MJSI sells a conversion kit that doesn’t cost much more than just replacing your toilet’s guts would anyway.
The HydroRight HYR270 converts your existing toilet into a dual flush toilet with a partial flush that uses 70% less water for liquid and paper and a full flush for solids (that’s their euphemism for poo). They claim you can install it in less than 5-10 minutes without tools and without removing the tank. As with any home repair it’ll probably take you 3 times as long unless you’re really, really motivated by the need to use the john after your third beer.
You’ll pay something like $20 to $25 for the HydroRight dual flush converter.
