EC5 Water Conditioning System

RainSoft EC5 water conditioning systems are available in various configurations with numerous features to fit your needs.

Ask your RainSoft dealer to recommend the EC5 water softening system that’s right for you.


The EC5 Series comprise RainSoft’s premium, computer controlled water conditioners. Built to last a lifetime, EC5 water conditioners provide dependable performance and an abundant supply of luxuriously softened water throughout your home. The EC5 provides real-time system status notifications for low salt, loss of power and power restored, service reminders for filter changes, and other useful reminders. These notifications are provided on both the system display as well as the RainSoft Remind® app.  They come standard with a smart-feature microprocessor controller that handles thousands of computations per second and responds in real time to your family’s home water treatment needs. The computer control keeps track of the water used in the home, and regenerates itself based upon actual water usage. This saves both water, salt, and electricity.

Benefits of EC5 Series Water Conditioners:


Softens, conditions and filters your water to remove calcium and magnesium – the two primary components of hard water.


The EC5 control valve is self-cleaning for maximum performance and long life. High flow rates assure a consistent, plentiful supply of conditioned water without worry of losing pressure. Powerful, self-lubricating 75-inch-per-pound drive motor.


A new, redesigned DC power supply uses less electricity than conventional AC power supplies found on other brands of water treatment equipment. There are also fewer moving parts, resulting in increased system reliability and long, trouble-free operation.

Fail-Safe Features

Exclusive brine valve float system reduces chance of overflow; automatic bypass during regeneration means you always have water; fail-safe tank-within-a-tank construction. A built-in battery back-up system maintains critical program data in the event of a power outage.


Carries RainSoft’s limited lifetime warranty for the treatment tank, value, and electrical parts–the finest and most comprehensive warranty in the industry!

Special Features

RainSoft Remind®, available for both iOS and Android, lets you monitor your EC5 system remotely, alerting you when your system needs salt or requires attention. You can even schedule service right from your smart phone or tablet. This system also features a redesigned interactive display.

How a EC5 Water Conditioning System Works:

Step 1

Down-flow Conditioning:

Untreated water flows through the filter media where hardness-causing minerals are removed.

Step 2

Up-flow Backwash:

The conditioning resin bed is “fluffed” to separate solids from the media.

Step 3

Down-flow Brining:

The system injects the exact amount of brine (salt water) made from filtered water needed for full-strength regeneration of the system.

Step 4

Slow Down-flow Brine Rinse:

Slow rinsing of the brine through the filter media provides a deep rinsing action to make sure all traces of salt are removed from the media bed.

Step 5

Fast Down-flow Rinse:

Fast down-flow rinse repacks the media, assuring maximum resin efficiency while removing any salt residue and any remaining traces of rust and iron.

Step 6

Treated Brine Makeup Refill:

TA precise, preset quantity of filtered water is used to make a clean brine solution for regeneration; other brands use raw, unconditioned water to clean the media bed.
