It may seem like a little drip, but a leaky shower head can add up to lots of gallons down the drain. According to the U.S. Environmental Protection Agency, a shower head that drips 10 times a minute – once every 6 seconds – wastes more than 500 gallons a year. That’s enough water to take showers every day for a month. Stop the leak and start saving. Often, it’s as easy as twisting on a new (water-efficient) shower head.
