EC5-CAB Water Conditioning System

The EC5-CAB Water Conditioning System Delivers Smart Performance You Can Count on for a Lifetime
RainSoft’s EC5 Technology provides unparalleled ease of use with features and benefits that ensure your family receives the finest water possible throughout your home.

The EC5-CAB water conditioning system goes beyond water softening to also filter, clarify, and polish your water, as well as reduce any ferrous iron it contains. A full menu of easy-to-use settings will allow you to customize the system to meet your family’s needs. This computer-controlled model is designed to ensure an uninterrupted supply of high-quality water for your home. It also calculates and uses the optimal amount of salt or potassium chloride and water at each regeneration based on household water usage. The EC5-CAB offers a smart, economical way to enjoy the best water possible and, like all RainSoft water treatment systems, it’s built to deliver a lifetime of reliable performance. Your RainSoft dealer can help you decide if the EC5-CAB is the best water softening solution for your home.

Step-By-Step
How does it work?
Ion Exchange
Untreated water flows into the resin tank, where hardness ions are retained in and on the special RainSoft resin.
Carbon Bed Filtering
The newly softened water can be further polished and clarified when it passes through an optional carbon bed.
Hardness Flushed Away
Perfectly conditioned water exits the EC5-CAB tank destined for household use, while hardness ions are flushed out and down the drain.
