Want to know how to save 1700 gallons of water a year? Install a faucet aerator! Aerators help faucets regulate flow, and some help maintain water pressure. Many faucets have no aerators installed at all.
Replace your standard 2gpm aerators with 0.5gpm aerators on every bathroom sink, and you will start saving water and money instantly. They only cost a few dollars each, can be purchased online, and require nothing more than a wrench to install. Happy savings!
