City Water Systems

Municipal water in the Twin Cities is treated and safe, but it typically carries hardness minerals plus chlorine or chloramine disinfectant. These systems soften and filter every tap in the house.

Well Water Systems

Private wells in Minnesota commonly carry iron, manganese and hardness, and in some areas hydrogen sulfide. Final well configuration depends on a water test — we review that with you by phone.

Fixture installation: the kitchen faucet under the sink is included with every tank RO.

Tankless units install under the kitchen sink. Financing options available — ask during your consultation. Travel fees may apply for installations beyond 35 miles from Minneapolis.

FAQ

Questions Homeowners Ask

How much does a whole-home system cost?
Every price is published on our pricing page. Whole-home city systems run $2,999 to $4,499 and well systems $4,499 to $5,999, with a reverse osmosis drinking-water system included free. Reverse osmosis on its own is $799 for the tank system or $999 for the tankless HW800 AlkaPro, a pre-sediment filter is $399 and a UV purifier is $899. Financing options are available, and travel fees may apply beyond 35 miles from Minneapolis.
Can the reverse osmosis system feed my fridge or be installed in the basement?
Yes, with the tank reverse osmosis system. Every tank RO includes the standard installation: the unit under the kitchen sink feeding its own kitchen faucet. Each extra run beyond that is an additional fixture. One additional fixture is $500, for example a line to the refrigerator from under the sink, or a basement installation that feeds the kitchen faucet. Two additional fixtures are $750, for example a basement installation that feeds both the kitchen faucet and the refrigerator. The tankless unit delivers water on demand without a pressure tank, so it has to be installed under the kitchen sink.
What warranty is included?
Whole-home systems carry a lifetime warranty on the tank and the valve, a 10-year warranty on the media (the carbon, resin and other consumable parts inside the tanks), and a 1-year warranty on labor. Reverse osmosis systems carry a 1-year warranty on the system and labor. We go through the exact terms with you on the phone before anything is installed.
