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.

How EC4 Water Conditioners Work

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 bed.


Other Benefits

  • All high-strength ABS enclosures fit tightly to protect control components from outside elements.
  • Ultraviolet inhibitor prevents degradation of materials by sunlight in outside installations.
  • Brine tank is equipped with overflow protection to protect against overflow due to power outages during regeneration.
