Kinetico took its best water softener and made it even better. With improvements that make them more efficient and effective, Kinetico Premier XP® softeners are ideal for homes with challenging water conditions.


Designed for homes with larger plumbing and high water use, Premier XP softeners deliver generous flow rates without giving up softness.
At least one tank is always in service, even during regeneration, and the system can regenerate at any time of day or night. A full house of guests or a big laundry day will not run you out of soft water.

Kinetico’s patent-pending XP feature allows more precise calibration to your home’s water, for efficient operation and less waste. It is like a softener that is custom-fit to your home.
Moving water powers the system, not electricity. There are no timers or computers to set, adjust, repair or replace.
The Premier XP S650 OD XP and Q850 OD XP were independently tested by the Water Quality Association to NSF/ANSI Standard 44, the industry rating for how much hardness a softener exchanges per pound of salt. Kinetico rates these two models the world’s most efficient water softeners.*
That means more soft water from every bag of salt, with less salt to buy and carry.
Your local Kinetico expert will match the right model to your home and your water. These are popular models; more models and sizes are available.

Hard water minerals build up inside water heaters, dishwashers and washing machines. A softener helps them run more efficiently and last longer.
Hard water leaves a residue behind. Soft water helps soap and shampoo rinse more completely, so skin feels cleaner and hair feels softer.
Scale can build up inside pipes and restrict flow. Softening helps reduce that buildup and supports better water pressure.
Say goodbye to white spots on faucets, shower doors and sinks. Soft water makes cleaning easier, with less effort.

Learn MoreA water softener reduces the calcium and magnesium that make water hard through a process called ion exchange. As water flows through the system, those minerals are drawn to charged resin beads and held there.
Installed where water enters your home, a softener treats all of it, so you have softer water for bathing, cleaning and everyday use.
Dry skin and hair, soap scum in the shower and white scale on faucets are common signs of hard water. Over time, hard water also adds wear to appliances like dishwashers and water heaters.
A free water test measures your hardness in grains per gallon, which tells you whether a softener is worth it and which size fits your home.
A trained professional connects the system to your home’s main water line, along with a drain line and the brine tank that holds the salt. Cardinal Water Solutions handles the installation and walks you through the system before we leave.
It depends on the size of the system, its features and your water. A professional water test is the best way to find the right system for your home, and Cardinal Water Solutions puts the recommendation and the price in writing before any work begins.
Sizing depends on the hardness of your water, the number of people in your household and how much water you use each day. A water evaluation lets us size the system so it keeps up with your home without waste.
