Reverse Osmosis Systems in Menomonee Falls
A reverse osmosis system puts a separate faucet at your kitchen sink for water you will want to drink, cook with and freeze into ice. We size it to your daily use, fit it neatly in the cabinet and route the drain line through the air gap Wisconsin plumbing code calls for.
Filtered drinking water from a dedicated tap
Reverse osmosis pushes water through a very fine membrane, with carbon stages before and after it. What reaches the faucet is noticeably cleaner in taste and clarity, which is why most people use it for drinking, cooking, coffee and the ice maker.
It treats the water you drink, not every tap in your home. If chlorine at the shower or spotting on fixtures is the real complaint, whole-home filtration or a water softener may serve you better, and we will say so plainly. Many homes pair a softener with reverse osmosis, since softened water is gentler on the membrane.
Every system we fit is installed by a licensed Wisconsin plumber. That matters most at the drain, where the wastewater line needs a proper air gap so nothing from the sink drain can ever find its way back into the system.
What the installation includes
- 01
Membrane and filter stages
A sediment prefilter, carbon stages and the reverse osmosis membrane, mounted on a bracket inside the cabinet with room left for easy cartridge changes.
- 02
Storage tank
A pressurized tank holds filtered water ready at the faucet. Our lifetime coverage on tanks, valve ceramic discs and dry mechanical parts applies here.
- 03
Dedicated faucet
A separate drinking water faucet set into an existing sink hole or a new one drilled through the countertop. We choose a finish that sits comfortably beside your main faucet.
- 04
Code-compliant drain connection
The reject water runs to the sink drain through an air gap, either built into the faucet or as a separate fitting. This is the detail inspectors look at and the one shortcuts tend to skip.
- 05
Optional refrigerator line
If you want filtered water at the fridge door and ice maker, we run a tidy line to it and test both before we leave.
Questions about Reverse Osmosis?
Call(262) 440-9018Signs a reverse osmosis system makes sense
Plastic bottles fill your recycling bin
Hauling cases home from the store adds up in cost and effort. A system under the sink gives you water you enjoy without the trips or the empties.
Coffee and tea taste off
Chlorine and dissolved minerals flatten the flavor of anything brewed. Filtered water lets the coffee taste like the coffee.
Cloudy ice cubes or a film in the kettle
Scale in the kettle and murky ice point to dissolved solids that reverse osmosis removes well.
Older plumbing in your home
Where pipes and fittings have some age on them, many families want an added layer of treatment at the one tap they drink from.
A pitcher filter that can't keep up
Pitchers filter slowly and always seem to be empty. A tank system keeps filtered water ready whenever you reach for a glass.
How the work goes
- 1
A conversation by phone
Tell us what bothers you about the water now, where your kitchen sink is and whether the refrigerator makes ice. From there we go over the system choices, the financing and what the quote will include.
- 2
A look under the sink
We check cabinet space, the cold supply valve, drain height and your countertop material. Your written quote holds for 30 days.
- 3
Install day
Floors and the cabinet base are covered before any tools come out. We shut off the cold supply, fit a new valve, mount the system on its bracket and connect the drain through the air gap, setting the faucet last.
- 4
Flush and walkthrough
The membrane is flushed, every joint is checked dry, and we show you where the filters sit and when they are due. Full payment comes only once the install is complete.
What shapes the price
Most installs are straightforward, but a few details change the scope. We point them out during the visit so the quote you sign matches the work we do. Financing is available through U.S. Bank Avvance, on approved credit.
- The system itself
- Tank or tankless designs, the number of stages and add-ons such as a remineralizing filter all move the cost.
- Your countertop
- Laminate drills easily. Quartz, granite and solid surface need more careful drilling, unless an existing sink hole can be used.
- Refrigerator connection
- A line to the fridge adds tubing and time, more so when it runs across the kitchen or through a basement.
- Cabinet and plumbing condition
- Tight cabinets, a garbage disposal in the way or an old supply valve that needs replacing can add steps.
Reverse osmosis questions
Does a reverse osmosis system waste water?
The membrane needs a steady flow to rinse away what it holds back, and that rinse water runs to the drain. Current designs send much less down the drain than older units did, and an automatic shutoff valve stops production once the tank is full. We will give you the reject ratio for the specific model we recommend.
Will the water taste flat?
Some people notice a very clean, light taste at first. If you would rather have a bit more body, a remineralizing stage adds back a small amount of calcium and magnesium.
How often do the filters need changing?
Prefilters and carbon stages are usually changed about once a year, and the membrane lasts several years depending on your water and use. We show you how the cartridges come out so you can decide whether to change them yourself.
Is a permit needed for an under-sink system?
Requirements vary by municipality, and we confirm what applies to your address before any work begins. In every case the reject line runs through an approved air gap and the drain connection is made properly, because that is the part of the job the plumbing code is concerned with.
Can I back out once I have signed?
Yes. The agreement gives you a window of three business days from the day you sign. Payment in full is due only after the system is installed and running.
