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:
Resin is "fluffed" to separate solids from the media.
Step 3. Downflow Brining:
System injects the exact quantity of brine 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 deep rinsing action to make sure all salt is removed from the media bed.
Step 5. Fast Downflow Rinse:
Fast downflow rinse repacks the medium, assuring maximum resin efficiency and 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 cleaner brine solution for regeneration; other brands use raw, hard water to clean the media bed.
