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.
