The Trionics Model ECO-CM Water Softener provide quality soft water at every tap in your home at an affordable price with the durability and reliability of commercial grade construction.

How Does It Work?

A water softener is an ion exchanger.

Hard water — water with a high calcium/magnesium content — enters the softener through the valve and into the tank where it goes from top to bottom through an ion exchange resin that “softens” it by removing the calcium/magnesium as well as other contaminants.

The ion exchange resin consists of beads that have been specially manufactured to be saturated with sodium ions. “Softening” occurs as the hardness minerals in the water attach themselves to the resin and are “exchanged” for sodium.

The softened water then enters the long center tube, called a riser, via the strainer basket in the bottom of the tank and passes upward through the riser. The water exits the softener through the control valve and is sent to the home.

When the resin becomes saturated by hardness minerals, the softener automatically goes into regeneration. (The regeneration process is initiated by a timer or a meter, of which the CS and EE Valve have both capabilities.) By this process the hardness minerals are washed down the drain (via a drain tube not shown in the diagram), and the resin bed is rinsed, resettled, and recharged with sodium. It is now ready to soften your water again.

The regeneration process is accomplished by passing very salty water from the brine tank through the resin.

The brine tank must remain filled with softener salt at all times so that it can regenerate the softening resin again and again.

ECO-CM Features


Manufactured from high-tech Noryl™ corrosion resistant materials and all internal parts are lead-free. The CM valve have been engineered to withstand the test of time for years of uninterrupted daily use.

Designed with ease of installation and service in mind, the CM valve feature advanced electronics for easy programming and minimal parts. Switches, cycle cams, wiring harnesses and wire nuts have been eliminated. These valves boast fewer parts than comparable systems, meaning easy service, and long-lasting reliability.

TRIONICS MODEL ECO-AC Whole House Chemical Filter/Softener

The Trionics Model ECO-AC filtering system provides quality soft and clean conditioned water at every tap in your home at an affordable price.

The Trionics Model ECO-AC is made with (GAC) granular activated coconut shell carbon for superior chlorine, taste and odor removal as well as organic compounds and disinfection by-products (DPB’s) such as chloroform and other trihalomethanes (THMs).

How Does It Work?

Carbon is a substance that has a long history of being used to absorb impurities and is perhaps the most powerful absorbent known to man. One pound of carbon contains a surface area of roughly 125 acres and can absorb literally thousands of different chemicals.

Activated carbon is carbon which has a slight electro-positive charge added to it, making it even more attractive to chemicals and impurities. As the water passes over the positively charged carbon surface, the negative ions of the contaminants are drawn to the surface of the carbon granules.

Activated carbon filters used for home water treatment typically contain either granular activated carbon (GAC) or powdered block carbon. The two most important factors affecting the efficiency of activated carbon filtration are the amount of carbon in the unit and the amount of time the contaminant spends in contact with it. The more carbon the better. Similarly, the lower the flow rate of the water, the more time that the contaminants will be in contact with the carbon, and the more absorption that will take place.

All Trionics activated carbon filters use coconut shell carbon. There are two principal mechanisms by which activated carbon removes contaminants from water; adsorption, and catalytic reduction, a process involving the attraction of negatively charged contaminant ions to the positively charged activated carbon. Organic compounds are removed by adsorption and residual disinfectants such as chlorine and chloramines are removed by catalytic reduction.
