Water softener installation

Getting the size, the setting and the plumbing right the first time saves salt for years.

A water softener installation in the Rochester area means picking a unit sized for hard water, setting it to your measured hardness, and plumbing it so the house gets soft water while lawn spigots don't. This page is for homeowners on city water or a private well who are buying their first softener or adding one to a new home.

Signs you'd benefit from a softener

  • White scale on faucets, showerheads and the dishwasher
  • Spotty glasses and cloudy shower doors
  • Soap and shampoo that won't lather
  • A water heater that rumbles or pops
  • Stiff laundry and dry skin
  • Crust inside the kettle or coffee maker

Why it's so common here

Rochester Public Utilities lists its water at 17 grains per gallon. Minnesota health and pollution control officials say softening may help once hardness passes about 7 grains per gallon, and most of the groundwater in this part of the state is well above that. Byron, Stewartville, Pine Island and private wells have their own numbers, so a test comes first.

What goes into the install

  1. Test. Hardness, plus iron if you're on a well.
  2. Size. Grain capacity based on hardness, household size and water use, so the unit regenerates efficiently.
  3. Plumb. A bypass valve, a drain line with an air gap, and outdoor lines left unsoftened where possible.
  4. Set. Program hardness and regeneration to match the test, not a factory default.

What affects the cost

The equipment type (timer, demand-initiated, twin tank), grain capacity, whether a pre-filter is needed, how much re-plumbing the spot needs, and whether a drinking-water system is added at the same time. The company you're connected with quotes after seeing the house. We don't set prices.

Salt or salt-free?

Salt-based ion exchange softeners remove hardness. Salt-free "conditioners" work differently and don't remove calcium and magnesium the same way, so results on hard Minnesota water vary. Ask the company to explain what a product does and doesn't do before you buy.

Common questions

How big a softener do I need?

It depends on your hardness, how many people live in the house and how much water you use. A company should size it from a test, not guess.

Do outdoor faucets need soft water?

Usually not. Minnesota guidance suggests softening only where needed, and leaving hose bibs and toilets on hard water can save salt.

Can I install a softener myself in Minnesota?

State law lets homeowners do water conditioning work on the home they own and live in, unless a local ordinance says otherwise. Paid work requires a state water conditioning or plumbing license.
