Enjoy softer water throughout your Johnston home and filtered drinking water at the sink. Kind Water Co installs softeners, carbon filtration and reverse osmosis, and helps restore performance in an existing system through diagnosis and repair.
Choose the improvement you want: fewer mineral spots, less chlorine taste, filtered drinking water or reliable softener performance. We install and service water treatment in Johnston, including supported equipment we did not sell.
Your free in-home screening measures hardness, iron and total dissolved solids in about ten minutes. We also review the main-water connection, drain, power and equipment space. Licensed local plumbing professionals we vet, schedule and stand behind handle installation. We confirm coverage and any travel charge before booking.
Softener plus carbon filtration is $2,500, or $2,850 with tank RO. Standalone RO is $897 tank or $997 tankless. Standard installation and taxes are included; optional work is quoted separately. A diagnostic trip is $199 with repair separate; a known-issue trip is $99 plus parts. Annual tank-RO care is $199 or tankless care $249.
To begin, request the free in-home water test or build a Central Iowa installed quote. Your Johnston water report explains the local supply and published test results, and the Polk County hub connects you with nearby service information.
| Johnston at a glance | What the record shows |
|---|---|
| Who supplies the water | Johnston municipal water service, maintaining the local distribution system |
| Where it comes from | Drinking water purchased from Des Moines Water Works, as documented by the City of Johnston |
| Softened at the plant | Regional treatment includes softening. Home treatment further reduces remaining hardness when selected from your tap readings |
| Your home’s hardness | Measured at your own tap during the free screening and used to set capacity and regeneration |
The City of Johnston buys treated drinking water and maintains the pipes that distribute it locally. We start with the water reaching your home, then match softening, carbon filtration and kitchen RO to the improvements you want.
Homes in Johnston, Des Moines and Urbandale can have different plumbing layouts and water use. We check your tap readings and simultaneous demand rather than sizing equipment from square footage or a regional average.
Whole-home treatment serves showers, laundry and fixtures. Kitchen RO gives you a separate option for drinking and cooking water. Our comparison of reverse osmosis against ordinary filters explains how to compare those options.
If chlorine taste or odor is your main concern, compare a carbon filtration stage. If mineral buildup is the problem, compare a softener. For filtered drinking water at a dedicated kitchen faucet, compare tank and tankless reverse osmosis.
We choose the carbon media for the supply’s disinfectant and check flow and service access during the visit. The Standard and XL whole-home packages include carbon filtration. Our carbon filtration guide explains the equipment and care schedule.
For a specific concern such as nitrate, a certified lab result guides the treatment plan. We can help evaluate an RO option and confirm the installation requirements before you choose.
Choose the package that fits your water and household. Published prices include standard installation and taxes. Whole-home packages include lifetime parts coverage, five years on media and one year on installation labor, subject to written terms.
Annual RO service is $199 for tank systems or $249 for tankless, including three RO filters, a water test and a full system check. A diagnostic trip is $199 with repairs separate; a known-issue trip is $99 plus parts. Ask about 0% financing with approved credit and the $100 military and first-responder discount.

A softener that leaves spots, uses more salt or fails to regenerate may need a setting change or repair. We check hardness before and after the system, bypass position, brine draw, valve operation and control settings. Supported brands include equipment we did not sell. A diagnostic trip is $199, with repairs separate; a known-issue trip is $99 plus parts. Our water softener repair guide covers simple checks, and the Des Moines metro repair page helps you compare repair with replacement.
For a Johnston-area property on a private well, we select treatment from the water results and installation layout. Municipal averages do not describe a private well. Our well water system starts at $3,650, or $3,950 with tank RO. The $700 Class B UV option supplements treatment of already-safe water and is selected for a suitable supply. Sediment filtration is $500 when appropriate. Additional laboratory results guide specific contaminant treatment. Begin with free well water testing.
Published prices, a clear care plan and a written installed scope make the decision easier. Licensed local plumbing professionals handle the installation, and our main Des Moines team supports Johnston at 515-709-4674. We review equipment selection, optional work and warranty terms before booking.
We measure hardness, iron, TDS and a nitrate screening reading at your Johnston home and explain what those readings mean for softening, filtration and RO. We check the installation layout and give you a written quote. For nitrate or another specific contaminant, we help you choose the appropriate lab test and plan treatment from the result.

Yes. A home softener can reduce the remaining hardness minerals that cause spots, soap film and scale. We measure your tap’s hardness and size the system for your household demand. Utility treatment does not replace that home-specific measurement.
Your home’s hardness is measured during the free screening. Regional information gives useful context, but your tap reading determines the softener’s capacity and regeneration settings. Bring us your concerns about spots, buildup or soap film so we can match the treatment to your goals.
A softener is the right treatment for hardness-related spots, soap film and mineral buildup. We confirm hardness at your tap and review household demand before recommending a size.
