Product Details
(Limited Availablility)
The SmartChoice™ II Twin water softener combines alternating twin tank design with advanced diagnostics to provide a continuous supply of soft water as well as advanced diagnostics. With our easy-to-read screens with low salt and service alerts provide information on system malfunction so you can take the right steps to make it right. It provides extensive information about water usage and can help identify plumbing leaks and other water wasters. And since each tank is used to its full capacity, there is no need for a reserve.
Modular design
Our SmartChoice water softener line features modular, exchangeable parts, making it the last softener you'll ever need to buy. Rather than replacing the whole system, bring us the part you need and we'll exchange it.
Highlights
Key Features

Uninterrupted 24-Hour Soft Water
Alternating twin tanks regenerate one at a time, so you always have soft water on tap.

Low Power Consumption
The SmartChoice II uses significantly less power and features an energy saving auto display turn off.
Smart Technology
The Smart Control Valve learns your water usage over time, so your softener only regenerates when it needs to. This saves energy and water.
Strong Warranties
It may be years before you need it, but the SmartChoice product line offers the strongest warranties in the industry. And after the warranty is up, you can always take advantage of our component exchange program.

Water Treatment FAQs
Do you offer free water testing?
Yes, Finken provides complimentary water testing for Minnesota homeowners. Our water specialists test for hardness, iron, pH levels, and other common contaminants to recommend the right water treatment solution for your home.
Do you repair water softeners?
Yes. Finken diagnoses and repairs most water softener makes and models across central Minnesota — including systems we didn't install. Common fixes include salt bridges, clogged brine lines, stuck valves, and failed regeneration timers.
Is reverse osmosis water safe to drink?
Yes, reverse osmosis (RO) water is very safe. RO systems remove up to 99% of contaminants including lead, chlorine, fluoride, and dissolved solids, producing clean, great-tasting drinking water. Finken installs and services RO systems for Minnesota homes.
What water softener brands does Finken carry?
Finken installs and services high-quality water softeners from leading manufacturers suited to Minnesota's hard water conditions. We offer a range of systems from basic to premium models, and our water treatment experts will test your water and recommend the best softener for your home's specific needs and budget.
How do I know if I need a water softener?
Common signs of hard water include scale buildup on faucets and fixtures, spots on dishes, dry skin and hair, stiff laundry, and reduced appliance efficiency. A free Finken water test will measure your water's hardness and show whether a softener would help.
