The best and most effective way to reduce toilet-related water use is to replace an older toilet with a new 1.6 gpf (gallons per flush) toilet. Even better, install a a new dual-flush toilet that provides both 0.8 gpf and 1.6 gpf flushes.

If installing a new toilet is not an option, however, these inexpensive devices can help reduce water use from older model toilets.
