Benefits of EC4 Water Conditioning System:
FUNCTION
Softens, conditions and filters your water to remove calcium and magnesium – the two primary components of hard water.
PERFORMANCE
The EC4 control valve is self-cleaning for maximum performance and long life. High flow rates assure a consistent, plentiful supply of conditioned water without worry of losing pressure. Powerful, self-lubricating 75-inch-per-pound drive motor.
ECONOMY
Powered by an energy-efficient, low-voltage 24-volt electrical system.
FAIL-SAFE FEATURES
Exclusive brine valve float system reduces chance of overflow; automatic bypass during regeneration means you always have water; fail-safe tank-within-a-tank construction. A built-in battery back-up system maintains critical program data in the event of a power outage.
RELIABILITY
Carries RainSoft’s lifetime warranty for the treatment tank, value, and electrical parts–the finest and most comprehensive warranty in the industry!
How a EC4 Water Conditioning System Works:
Step 1 - DOWNFLOW CONDITIONING:
Untreated water flows through the filter media where hardness-causing minerals are removed.
Step 2 - UPFLOW BACKWASH:
The conditioning resin bed is “fluffed” to separate solids from the media.
Step 3 - DOWNFLOW BRINING:
The system injects the exact amount of brine (salt water) made from filtered water needed for full-strength regeneration of the system.
Step 4 - SLOW DOWNFLOW BRINE RINSE:
Slow rinsing of the brine through the filter media provides a deep rinsing action to make sure all traces of salt are removed from the media bed.
Step 5 - FAST DOWNFLOW RINSE:
Fast downflow rinse repacks the media, assuring maximum resin efficiency while removing any salt residue and any remaining traces of rust and iron.
Step 6 - TREATED BRINE MAKEUP REFILL:
A precise, preset quantity of filtered water is used to make a clean brine solution for regeneration; other brands use raw, unconditioned water to clean the media bed.

Our Testimonials
We live a considerable distance away from the city where Rain Soft is located but have never had any problems with the system itself. We were proud to recommend it to our son when he brought the place from us. He has no problems as of this date. Thank you for your service!
Rainsoft is a great product that comes with great service. We feel it was an investment, but we feel it was worth it. We have the Ultrefiner Drinking Water System that we use for all of of water bottles on the go - they stay clean - no yellow or pink film…. The Water Conditioning System is efficient and we used about 6 bags of salt in the last year - active family of 2 with family stopping in. Would highly recommend Rainsoft.
We have been with Rain soft since 1999. We recently purchased a new softener and decided to stay with Rain soft because of their excellent service and quality of product. We have had the reverse osmosis system since the beginning and have also added the chlorine removal tank. We enjoy having the quality water that our system provides us with. Thanks to rain soft. Brent and Carla Whitlock.
Will make this short. Had some problem with our water softener. Had water on the floor. It would make all kinds of noise and the our water softness was inconsistent. Lucas came and took the time to fix it right! Our water softener has never worked this well. Be sure to let Lucas know much we appreciated his work!!
RainSoft has delivered excellent service and products since we installed a whole house water system more than 20 years ago. We recently replaced our refrigerator and RainSoft came the next day to connect the new water line for our ice/water. Prompt and friendly service!
Blake was awesome and the warranty on the products is very good. Blake took the time to replace all potential problem parts in the system at no additional charge. Living in the country with well water is hard on the system but I don’t know what I would do without it. Blake also had some extra bags of salt on hand to save us a trip. Very professional and obviously took pride in doing things right!
