The ERR 3502 Water Refiner from EcoWater

The latest technology for water treatment.  Featuring the patented HydroLink© and HydroLinkPlus© Remote Monitor

What is a whole home water refiner?

A whole home water refining system is the perfect choice for those who need an economical method for treating their water by removing mineral deposits (or softening) and chlorine taste and odor (refining).  A softener by itself does NOT generally remove chlorine.  The ERR series also comes with a patented HydroLink® monitor that displays the following:

  • Valuable water usage information to help manage water consumption.
  • The system salt level, and number of days before salt is needed.
  • Gallons of capacity before the next regeneration.
  • Amount of hardness removed from your water.
  • Confirmation that the system is working properly.
  • Notice if the systems need service.

A Detailed Look at the ERR 3502 Refiner

The ERR 3502 boasts many features that can't be found in other water filtration systems.


1. HydroLink® and HydroLinkPlus® Remote Monitor

Patented two-way remote monitoring or Wi-Fi enabled technology and smartphone app. Model ERR 3502R50 available as Wi-Fi only.


2. Patented Electronics Digital Demand Module

Sophisticated, yet easy-to-use electronics capture historical usage patterns to predict future needs for precise regenerations.


3. Multi-Wrap Fiberglass Reinforced Resin Tank

Durable tank liner will not deteriorate, rust, or corrode.


4. Full One-Inch Riser

One-inch diameter for increased flow rates, which ensures that household demand is adequately met.


5. Coconut-Shell Carbon with Lifetime Warranty

Sophisticated, yet easy-to-use electronics capture historical usage patterns to predict future needs for precise regenerations.


6. Patented Stratified Resin Bed

Layered mix of fine and standard size resin provides superior filtration and iron removal without sacrificing flow rate capability.


7. Positive-Action Brine Valve

Snap-together construction eliminates use of solvents that may contaminate water. Positive action helps prevent overfilling.


8. Self-Cleaning Distributors

Distributors exhibit excellent flow rates and are cleaned automatically by counter-current water pressure.


9. Washed Quartz Underbedding

Helps provide a cleaner, more thorough regeneration of the resin.

The ERR 3502 Cutaway

Comes with the brine tank, system tank, and remote controller.

1 Intermittent flow rate does not represent the maximum service flow rate used for determining the refiner’s rated capacity and efficiency. Continuous operation at flow rates greater than the certified flow rate may affect capacity and efficiency performance. The validity of these flow rates is verified by NSF.
2 When operated at 35 psi water pressure.
3 Maximum pressure for Canadian use is 7.0 Kg/cm2.
4 Typical residential chlorine concentration is 0.5 to 1.0 ppm.
5 From independent laboratory test data.
