Sloan Valve Co.'s Act-O-Matic 2.5-gpm flow showerheads combine self-cleaning capabilities with a "Cone-Within-A-Cone" spray. The showerheads use a pressure compensating flow control that provides a consistent and powerful flow at low pressures, resulting in water savings. The chrome-plated, all brass showerheads incorporate a self-cleaning spray disc that eliminates sand and other particles after each use. When the water is turned off, the disc retracts to its fast drain position. Sand and other particles are then washed away. The fast drain position also prevents residual slow dripping after showerhead use. Act-O-Matic standard models come with or without thumbscrew, and there is an institutional style with integral mounting flange.Sloan Valve Co.
