Description Specs FAQs Precise, simple, and reliable are words that describe D20S. Installed directly in the water supply line, the Dosatron operates by using water pressure as the power source. The water activates the Dosatron, which takes up the required percentage of concentrate. Inside the Dosatron, the concentrate is mixed with water. The water pressure forces the solution downstream. The dose of concentrate will be directly proportional to the volume of water entering the Dosatron, regardless of variations in flow or pressure which may occur in the mainline.
