How Kinetico Water Softeners Work

John Albers

Kinetico water softeners, whether the compact well-water or a city-water designs, all utilize a three tank system where the standard for water softeners is two. There is the mineral tank and the brine tank, as usual, and a third tank for soft water once it’s been treated.


This allows for an almost continuous supply of softened water without having to wait for the system to clean itself. The traditional backwash phase begins with the mineral tank emptied after its cleaned contents are shifted to the reserve tank. Nothing but zeolite, simple polystyrene beads, fill the mineral tank. The previous running cycle has left them covered with debris. The contents of the brine tank is flushed through the mineral tank to clear out the sediment and then the brine is pumped out the wastewater line. It should be noted that the Kinetico water softeners, rather than using an electric pump, rely on a patented turbine to move the water from tank to tank. This makes them more efficient and cheaper to run.


Water enters the mineral tank from the outside supply; either a well or city connection. It should be noted that hard water is water which contains abnormally high amounts of calcium and magnesium, which can yellow the water and make it difficult to use for cleaning, let alone drinking. Both calcium and magnesium are positively charged elements while the zeolite is negatively charged. This means that the calcium and magnesium adhere to the zeolite, and so the softened water is pumped into the reserve tank.


As more water fills the mineral tank to be softened, there reaches a point where the zeolite becomes too heavily covered with debris from the hard water to function anymore. Actively running, this takes about forty-five minutes between cycles. That’s why, just before that time elapses, the Kinetico water softener pumps the brine tank full of soft water in order to allow the cleaning and refilling process to repeat.
