Showerhead replacement or modification represents another water efficiency area that is cost effective. Most conventional showerheads use 3.0 to 7.0 gpm at 60 psi water pressure. Current standards require showerheads to use no more than 2.5 gpm. These new water efficient showerheads come in many different models and features and typically perform very well. Water efficient showerheads also reduce energy consumption related to hot water generation. The EPA, through its WaterSense program, is currently developing specifications to establish a maximum flow rate between 1.5 and 2 gpm at a pressure of 80 psi. This flow rate represents a 20 to 40 percent reduction over the current 2.5 gpm rate.
