Delta Water Amplifying Adjustable Showerhead
The dual setting shower head offers a water-saving comfort spray and a high-volume spray. The water-saving comfort spray operates at 1.85 gallons per minute, but don't think you're giving anything up in performance because it feels like the standard 2.5 gallons per minute. So you save water and energy. And that is a very good thing these days!
