If you’re walking away from the kitchen or bathroom faucet or shower while the water is running, think again. For example, leaving the tap on while brushing your teeth uses around 8 gallons of water a day. In a year, that adds up to over 36 bathtubs of water down the drain. Remember, tap water is cleaned and purified, which also uses resources and energy. Make a bigger impact by installing low-flow shower and faucet heads. It’s easier than you think!
