US Water Systems Flexx Pro Series Water Softener With Smartphone Programming

This Softener Might Be Right For You:

  • If you are tired of replacing your big box store brand water softener (Kenmore, GE, Whirlpool, Morton, WaterBoss) every few years but don't want the expense of other high-priced water softeners, the FLEXX might be right for you.
  • If you want all the features of a much more expensive system, but need a budget price, the FLEXX might be right for you.
  • If you want to eliminate those primitive dinosaur programming buttons, the Waterlogix App is available for FREE on your Apple or Android smartphone.
  • If you are looking at a Fleck 5600, Fleck 5812, Fleck 2510 or any other Fleck Valve type water softener, the FLEXX PRO SERIES beats them every step of the way, especially the warranty.
  • If you want a water softener with a REAL WARRANTY on the valve and electronics, not one like Fleck that does not cover the internal parts, then the FLEXX and its 7-Year Warranty on the Valve and Electronics might be just what you want.
  • If you insist in Made in America products, then the FLEXX is definitely for you.

Why Does the Flexx Come with a Free Magna Filter?

At US Water Systems, we provide much more than just pieces and parts. We engineer solutions… Solutions that solve water problems. One of the most important parts of any water treatment system is proper pre-treatment and that usually starts with pre-filtration. If anyone says that you don’t need a pre-filter with a water softener, they are either ignorant or a charlatan! Your car will run without an oil filter… but it will run longer, better, and more efficiently with one. The same is true of a water softener. Even on city water, there can be sand, silt, sediment, and solids that can damage internal parts and plug the injector.

Magna mean “great” in Latin and this is a great filter. It is 5 microns to effectively remove anything that can damage your water softener. It has almost double the surface area of other filters and is the BEST INSURANCE POLICY there is to protect your water softener…and all water using appliances in your home.

Unlike other “Big Blue” filters which are Made in the Far East, the US Water Systems Magna Filter is 100% American Made and is the only filter on the market that has a double o-ring Positive Seal that assures 100% filtration. Old-style “flat top” filters cannot even come close to this level of filtration.
