Picture
Always at the forefront of innovation, RainDance Water Systems twin sediment filters  feature cutting-edge technology that provides your home or business with sediment and turbidity filtered water 24/7 and works at optimum efficiency.
Compare The Difference: Single-tank sediment filters can’t backwash and filter your water at the same time, so there may be times that untreated sediment flows into the plumbing. Our twin tank systems, such as the Twin RDWS-NS offered by RainDance Water Systems, don’t suffer from this problem. They keep filtering high sediment in your well water 24 hours a day, seven days a week. Perfect for irrigation, large households, and high water usage applications.
