Start with your water, not a sales pitch
Vernon Hills water comes from Lake Michigan through the Lake County Public Works system. The utility publishes a water quality report that lists chlorine, fluoride and lead results, but we have no hardness number we would rely on, so the right move is to test your own tap.
A simple test tells you hardness, chlorine and sometimes iron. Many homes need nothing. Some want a softener for scale and spots, a carbon filter for taste or a reverse osmosis unit for drinking water. We explain what each does and does not do.
Problems treatment can help with
Treatment fixes specific problems. These are the symptoms people call about.
White scale on fixtures and kettles
Hardness minerals leave a crust. A softener reduces it.
Spots on dishes and glass
Dissolved minerals dry on the surface.
Chlorine taste or smell
A carbon filter removes much of it.
Dry skin and soap that does not lather
Hard water makes soap less effective.
Short appliance life from scale
Scale in a water heater lowers efficiency.
Treatment options compared
Match the system to the measured problem. A test beats a guess.
| System | What it does | Notes |
|---|---|---|
| Salt-based softener | Removes hardness minerals with ion exchange. | Needs salt and a drain connection. Check local rules on discharge. |
| Carbon filter | Reduces chlorine taste and odor. | Cartridges need regular replacement. |
| Reverse osmosis | Filters drinking water at one tap. | Wastes some water and needs maintenance. |
| Sediment filter | Catches sand and rust particles. | Common for well or old pipe issues. |
Softener or filter leaking?
Call the 24/7 line. We will tell you how to bypass or shut it off and send a technician.
Installing and servicing systems
A softener connects to the main water line, a drain and an outlet. We install a bypass so you can isolate the unit, and we set the hardness and regeneration schedule. Filters go where the water line enters or at a single tap.
Service includes valve repair, resin and media replacement, brine tank cleaning and control head repair. We also replace failed units. If a system leaks at a fitting, the issue may be a connection and the repair is quick.
Water heaters and scale
Hardness minerals collect in water heaters, especially tankless units, which need descaling. A softener reduces this, and flushing helps either way. See our tankless water heater page for descaling and our water heater repair page for tank issues.
If your water is discolored, rusty or low in pressure, the problem may be the pipes and not the supply. Our repiping page explains that case. A treatment system cannot repair corroded pipes.
What treatment systems cost
Price depends on the system, the size of the home and the install. We give a clear price before work starts and explain the ongoing costs of salt, cartridges and service.
Insurance does not cover treatment systems. Ask about the manufacturer's warranty on the equipment.
Code and permits note
Follow the maker's installation guidelines. A softener or filter ties into your supply and drain lines, so the connections follow the Illinois State Plumbing Code that the village cites. The utility's water quality report is the place to start, and it does not give a hardness figure we would rely on.
Test your own tap before you size anything.
Water treatment questions from Vernon Hills homeowners
Yes. Our line is answered 24 hours a day, every day. A leaking softener or filter housing gets priority. We tell you how to bypass it and send a technician. Same-day appointments are offered when available for service visits.
Not always. Test your tap first. Scale, spots and dry skin are the usual reasons people want one.
The utility publishes a water quality report each year. If you have a concern, such as lead from old plumbing, ask the utility and consider testing.
It depends on hardness and household use. Modern units regenerate by demand to limit it.
Usually yes. We repair valves, replace resin and clean brine tanks on most brands.
