Watershield 9100 Twin Tank Softener

Abstract Water

This Twin tank water softener has two resin tanks and a separate salt/brine tank. Twin tank units are always metered (demand), using an electro-mechanical metering system. Electro-mechanical metered water softeners measure water consumption with a turbine that turns as your water is used. The Twin tank system always has a fully regenerated tank available on standby, and deliver an uninterrupted 24 hour supply of softened water. During regeneration, water is first passed thru the online tank before entering the tank undergoing regeneration - regeneration using this pre-treated water helps clean the system and extends the water softener lifetime.

A water softener will improve your quality of life and save you money. Mineral build-up caused by un-softened water will no longer occur on pipes, fixtures and equipment.

Fleck Controls, Inc. traces its history back to 1950 when it began operations as L.W. Fleckenstein, Inc., a machine shop in Milwaukee, Wisconsin. In 1958the firm entered the water conditioning industry manufacturing steel covers for resin tanks. Shortly thereafter, Fleck recognized a need for a better brine valve in order for automatic water softeners to become a reality and began manufacturing this product. The development of a water softener valve began in 1963 and their first valve was introduced that year. Since then, Fleck has grown to produce innovative products in their field of business, always improving upon and testing newly updated equipment. A commitment to superior product quality and customer support and service is another cornerstone of Fleck's business philosophy.
