An enhanced version of CASPAK, a computer-aided sizing software program, is available online from Leonard Valve Co. This free program was developed to help design engineers select master mixing valves used in domestic water applications. This version of CASPAK has been updated to include water-efficient showerheads. Sizing techniques are based on parameters from the American Society of Plumbing Engineers' Data Book and the performance characteristics of Leonard thermostatic mixing valves.
