The latest technology for water treatment ... from EcoWater.
Scroll down to examine the exclusive features of the ESD 2502 water softener.
Optional Bypass Valve
Brass-free and lead-free bypass valve lets you manually bypass the system.
Sophisticated, yet easy-to-use electronics capture historical usage patterns to predict future needs for precise regenerations.
Multi-Wrap Fiberglass Reinforced Resin Tank
Durable fiberglass -wrapped tank liner, doesn’t deteriorate, rust, or corrode.
Distributors exhibit excellent flow rates and are cleaned automatically by preventing clogging.
Controls water flow in and out of salt tank. Features automatic shut-off to prevent overfilling.

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 Increased amounts of clear water iron can reduce softeners efficiency. Refer to owner's manual for details. Wisconsin requires additional treatment if water supply contains greater than 5 pm clear water iron.
3 When operated at 35 psi water pressure.
4 Maximum pressure for Canadian use is 7.0 Kg/cm2.
Power Outage Backup 6-hour program memory saves all data and settings in the event of a power outage.
Energy Efficient Power Supply Simplifies installation, maintenance and reduces electrical hazards.
Barium and Radium Reduction, and Low Lead Content This softener has been tested and certified by NSF International against NSF/ANSI Standard 44 for the reduction of Barium and Radium 226/228, hardness reduction and efficiency and NSF/ANSI 372 for low lead content.
