EC4 Series Water Conditioners

EC4 Series Water

RainSoft EC4 water conditioning systems are available in various configurations with numerous features to fit your needs. Ask your RainSoft dealer to recommend the EC4 water softening system that’s right for you.

The EC4 Series comprise RainSoft’s premium, computer controlled water conditioners. Built to last a lifetime, EC4 water conditioners provide dependable performance and an abundant supply of luxuriously softened water throughout your home. 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 and electricity.


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


The EC4 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.


Powered by an energy-efficient, low-voltage 24-volt electrical system.

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-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 offer in the industry!

ec4_howHow an EC4 water conditioning system works:

Step 1. Downflow Conditioning:

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

Step 2. Upflow Backwash:
The conditioning resin bed is “fluffed” to separate solids from the media.

Step 3. Downflow 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 Downflow 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 Downflow Rinse:

Fast downflow 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:

A 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.

Whole House Chemical Filtration System

qrsWhole House Chemical Filtration Is Perfect For
Homes With Municipally- Treated Water

RainSoft Whole House Chemical Filtration Systems are designed to help solve special water treatment problems, and are built for
long life and trouble-free operation.

System Features:
Tank-Within-A-Tank Construction

Rugged tank is wound with over 3 miles of glass filament for extraordinary strength. Inside there’s another tank of sanitary plastic so your drinking water will never touch the
interior fiberglass surface.

Downflow Model
Filters out sediment as well as removing unwanted tastes and odors.

Specially Graded Filter Media
HYSULEX II (H) is a highly activated carbon with acres and acres of surface area to adsorb bad tastes and odors as well as other
unwanted substances in your water. A more porous material than regular carbon, with a highly developed internal surface area, it provides a greater capacity for adsorption.

Manufactured to be cleaner, stronger and harder than the industry standard.
NOTE: Tank size and local water pressure will affect unit’s operating flow rate.

Application Limitations Water to be filtered should be free
of oil and suspended matter, and relatively free of iron and turbidity
for maximum service life in taste and odor removal. Actual results may vary based on local water conditions.

Maintenance Requirements Filtering media will eventually become exhausted or consumed and need replacement. Replacement schedule will depend on incoming water quality and amount of water used. Your local RainSoft dealer can provide you with the recommended replacement schedule for your particular application.



What is CleanStart®?

CleanStart® is an innovative, eco-friendly laundry solution designed to save you money and provide the cleanest, freshest laundry you’ve ever experienced!

Designed and engineered for the home, CleanStart® utilizes the same commercial cleaning technology found in larger systems we’ve provided to clients such as Hilton and Marriott for their laundry operations.

Here’s How It Works

CleanStart® transforms cold water into a powerful cleaning agent by oxidizing normal tap water, injecting a controlled amount of ozone (O3) into the wash water. Ozone is nature’s safest, strongest oxidant and most effective disinfecting agent. After the ozone oxidizes and disinfects, it reverts to oxygen leaving behind nothing but cleaner, fresher laundry!
