EC4 Water Conditioners

RainSoft EC4 water conditioning systems are available in various configurations with numerous features to fit your needs. 

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 and filtered 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.

Function

Softens, conditions and filters your water to remove calcium and magnesium – the two primary components of hard water.  Removes up to 99% of water soluable lead, mercury, nickel, chromium and other dissolved metals, chlorine*.  Effective at controlling the buildup of bacteria, algae, fungi and scale*.

Performance

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.

Economy

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.

Reliability

Carries RainSoft’s limited lifetime warranty.

How 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.
