Common questions
How much should a new water softener system cost?
Cost guides put a typical installed softener at $1,100–$3,000, averaging about $2,500 (Fixr). Twin-tank systems for larger households run $1,000–$5,000 (HomeAdvisor). A quote based on your measured hardness is what counts.
Is there a downside to a water softener?
A few. It needs salt and periodic service, and RPU's 2025 report notes that home softening raises the sodium in your water. Its brine discharge also carries chloride; the MPCA says softeners are likely the main chloride source for most Minnesota wastewater plants. A demand-based valve and RO at the kitchen sink reduce both concerns.
What is a good alternative to a water softener?
It depends on the goal. For drinking water only, reverse osmosis at the sink. For scale alone, salt-free conditioners reduce buildup without removing minerals, though at 17 grains they do much less than a softener. For taste, a carbon filter. None of these actually softens the water.
Is Minnesota water hard or soft?
It varies by source, so read your own utility's report. In Rochester the answer is clear: Rochester Public Utilities rates its water at 17 grains per gallon (280 ppm), which it calls very hard, and points to the limestone bedrock under the city as a cause.
Is softened water safe to drink?
For most people, yes, but it does carry extra sodium, and RPU's report points this out. People on a low-sodium diet often leave one cold tap unsoftened or drink RO water. Ask your doctor if sodium is a concern for you.
Who is allowed to install a softener in Minnesota?
A licensed plumber, or a licensed water conditioning journeyworker or master, working under a business with a water conditioning contractor's license (Minn. Stat. 326B.55). The Minnesota Department of Labor and Industry has an online license lookup.
Can I install my own softener?
Minnesota law exempts an owner doing water conditioning work on the home they own and live in, if it meets Plumbing Board standards and no local ordinance prohibits it (Minn. Stat. 326B.55). The drain still needs an air gap.
