EC5 Series System Features
- Immediate Condition Response: The system instantly displays its status and any relevant messages when a button is pressed, ensuring you're always informed.
- Automatic Power Outage Recovery: If the power goes out during a regeneration cycle, the EC5 automatically resumes and completes the cycle once power is restored—ensuring you always have softened water.
- Real-Time Alerts: Receive timely notifications for low salt levels, power interruptions, and service reminders. Alerts are shown both on the system’s LCD screen and within the RainSoft Remind® app.
- Advanced Display: A six-line LCD screen provides clear, easy-to-understand system information and is angled for optimal visibility.
- Energy-Efficient Design: The EC5 features a low-voltage DC power supply for reduced energy usage and fewer moving parts—leading to increased durability and less maintenance.
- Proportional Brine and Rinse Technology: This feature optimizes salt and water usage based on actual household consumption, reducing waste and increasing efficiency.


How the EC5 System Works

Step 1: Water enters the EC5’s robust control valve and flows through the ion exchange resin bed, where hardness minerals like calcium and magnesium are removed.
Step 2: Conditioned water exits the tank and is distributed throughout your home.
Step 3: At preset, metered intervals, the system initiates regeneration during off-peak hours. Using a salt-based solution*, the accumulated hardness minerals are flushed out and the system resets for the next cycle.
Advanced Operating Features
- New LCD interface with easy-to-navigate menus
- Fully customizable settings to fit your home’s water usage
- Intelligent computer-controlled regeneration prevents lapses in treated water
- Automatic adjustment for daylight savings time
- Retains time for up to one week without power; system settings are stored indefinitely
- Precisely calculates salt and water requirements for each regeneration cycle
Additional System Benefits
- Durable, injection-molded enclosures help shield control components from environmental exposure**
- Built-in overflow protection safeguards against brine tank overfill during power outages
- Full system status and operational data accessible from both the control panel and the RainSoft Remind® app (app use is optional for system operation)
* Potassium chloride may be used instead of salt.
** Outdoor Model only.

We recently had a system installed, and had a great experience working with Great Lakes Water Treatment. The 3 biggest positives: 1) Health: the taste and convenience of the filtered water system has translated into us drinking much more water than we were before 2) Hair: the softened water is much nicer for hair texture and 3) Great install experience: Dom did a great job getting the system set up in a nice, compact way. Thank you!
Absolutely fantastic service and product! Every step of the way, the install and information was first rate. My tap water no longer smells like a swimming pool, and I can drink the Reverse Osmosis without a care. Also, the detergent free washing machine unit is a marvel! I was skeptical, but it's better than advertised. Thanks so much!
