The Power of a Smart Dual-Tank Water Softener
Uninterrupted Softening
Dual tanks provide a continuous supply of soft water 24 hours a day, even during regeneration.
Unmatched Reliability
Dual Quadra-Hull® tanks make this hard water softener system extra durable, built to withstand UV rays, rust and corrosion.
Customized Softness
Culligan’s Dial-a-Softness® control puts you in charge of how your water feels.
Flexible Fit
Choose from a variety of water softener system sizes built to fit in the laundry room, basement, garage and more.
Twin Tank Water Softener System Options
Choose from four dual-tank water softener sizes and indoor or outdoor installation. Your local Culligan water expert will provide recommendations based on your water flow, usage, hardness and pipe size. They may also recommend additional product options to address any other water issues or needs you may have.
Proportional Brining
Increase efficiency and reduce salt usage by allowing your twin tank water softener to only regenerate the part of the resin bed that has been exhausted.
Aqua-Sensor®
This patented technology adjusts to changes in water hardness so it only regenerates as needed, enabling more efficient operation.
Salt Level Monitor
Effortlessly maintain your hard water softener system with a monitor that tells you how many days of salt are remaining in your tank, with notifications available through the Culligan Connect App.
Leak Sensor
Experience comfort and peace of mind with an external leak sensor that can detect leaks around your tank as well as nearby water-using appliances. If detected, you’ll receive alert notifications right through our app.
100% Satisfaction Guarantee
If you are dissatisfied with your Culligan product for any reason within 30 days of your purchase, Culligan will remove the product and refund the purchase price.
