Dual flush toilets have been around for awhile, but now local plumbers know what they are - not the case a few years ago. Simple tech, makes a lot of sense. On a trip to Europe and Israel I photographed a few different styles back in the day.
In a typical household, a toilet consumes the most water—roughly 27 percent of the total, according to the Environmental Protection Agency. A dual-flush model cuts that usage by providing full flushes to dispose of solid waste and half-flushes for liquids.
But before you pay $300 or more for a new toilet, you may want to consider a conversion kit for your existing unit. Available for $99 at major retailers, the Perfect Flush works with a top-mounted push-button box. It takes about 30 minutes for a homeowner to install and can save a family of four about $100 a year in water costs, the company says.
