I love the new technology in showerheads from Waterdecor. It lets you customize the waterflow instead of being set to a fixed GPM (gallons per minute). Low flow is anything under 2.5 GPM. These showerheads can be set in a range from .5 to 2.2 GPM. Considering that a typical household of four people consumes approximately 9,000 gallons of water per month or 108,000 gallons per year –enough to fill a bathtub more than 2,500 times – every gallon saved counts.
