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.



The ERR 3502 Refiner

The Latest Technology for Water Treatment

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
Filters the water throughout the home without compromising water flow. Removes chlorine taste and odor, extends resin life and eliminates the need for a separate carbon filter and filter changes.

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.

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.
