Better Water Industries Inc.’s G-140 Sentry I Open-Air System, often described as a personal municipality for the home, combines aeration with chlorination to provide superior water quality. This system adds air to the water with an adjustable Venturi, which starts the oxidation process and dilutes any gases in the water, such as methane. While the unit fills, the chlorinator dispenses the exact amount of chlorine desired, which sanitizes the water and finishes the oxidation process. This G-140 has three floats, one mechanical safety overflow, one electrical low-level shutdown and one electrical water-level maintaining float. It is complete with the chlorinator, bypass, bladder tank and pump, and is pre-wired for easy installation. http://www.betterwaterind.com, bwi@betterwaterind.com
