The manufacturer's 25 showerhead models can be equipped with a low-flow regulator that will reduce water usage to 1.75 gpm. The regulators keep the pressure and flow of the water strong, according to the maker. A portion of the company's showerheads can be operated at 1.5 gpm and still perform well, and all of the company's handshowers also can be equipped with the low-flow regulator. 800-852-3906. www.jaclo.com.
