PWS20-L
Watts Pure Water Simplex Water Softening Systems with Grain Capacities Ranging from 90,000 to 600,000
PWS20-L Watts Pure Water Simplex Water Softening System Series offers a robust lineup of high-efficiency, conventional cation exchange water softeners designed for point-of-use and point-of-entry applications. These systems are ideal for residential, commercial, and light industrial environments where the benefits of softened water—such as reduced scale buildup and improved appliance longevity—are essential.
Each unit in the series features the advanced Watts LOCKSMITH™ control valve, a corrosion-resistant brass valve that is highly configurable and easy to maintain. Operated by an electronic controller, the system stores key operational history and supports metered, demand-initiated regeneration, ensuring regeneration only occurs when necessary—saving water, salt, and time.
With grain capacities ranging from 90,000 to 600,000, and mineral tank diameters from 14 to 36 inches, each system contains 3 to 20 cubic feet of high-capacity ion exchange resin. Flow rates span from 55 to 119 gallons per minute, and all models include NSF and ANSI certified components with standard 2" FNPT inlet/outlet and 1" to 1½" MNPT drain connections, depending on the model.
These simplex systems efficiently exchange scale-forming calcium and magnesium ions with non-scale-forming sodium ions, delivering consistent soft water performance across a wide range of applications.
