Benefits of EC4 Series Water Conditioners

1. Function
The EC4 system softens, conditions, and filters your water by removing calcium and magnesium—the key minerals responsible for hard water.

2. Performance
Equipped with a self-cleaning control valve, the EC4 delivers long-lasting, high-performance operation. High flow rates ensure a steady and reliable supply of conditioned water without sacrificing water pressure. The powerful 75 in-lb, self-lubricating drive motor ensures smooth, dependable operation.

3. Economy
The EC4 runs on an energy-efficient 24-volt low-voltage electrical system, helping to reduce overall energy consumption.

4. Fail-Safe Features
A specially designed brine valve float system helps prevent overflow, while an automatic bypass function ensures uninterrupted water supply during regeneration. The durable tank-within-a-tank design adds an extra layer of reliability. Plus, a built-in battery backup retains essential program settings during power outages.

5. Reliability
Backed by RainSoft Great Lakes Water Treatment’s limited lifetime warranty on the treatment tank, control valve, and electrical components—one of the most comprehensive warranties available in the industry.

How a RainSoft Great Lakes Water Treatment EC4 Water Conditioning System Works

Step 1: Downflow Conditioning
Incoming water flows downward through the conditioning media, where minerals responsible for water hardness—like calcium and magnesium—are effectively removed.

Step 2: Upflow Backwash
The system reverses flow direction to gently lift and agitate the resin bed. This action loosens and flushes out trapped particles and sediment.

Step 3: Downflow Brining
A precisely measured amount of brine, made using filtered water, is introduced into the system to fully regenerate the resin bed for optimal performance.

Step 4: Slow Brine Rinse
A slow rinse cycle allows the brine to move evenly through the resin bed, ensuring deep rinsing and the removal of residual salt from the media.

Step 5: Fast Rinse
A high-flow rinse compacts the resin bed to restore efficiency while flushing out any remaining salt, rust, or iron particles.

Step 6: Treated Brine Refill
The system uses a set amount of filtered water to prepare clean brine for the next regeneration cycle—unlike many other systems that use untreated water for this step.
