Reverse Osmosis Systems in Menomonee Falls
Better water for drinking, coffee and cooking, from a small system that fits under your kitchen sink. We cover your floors, tell you what we're doing before we do it, and leave the cabinet as tidy as we found it.

Clean Drinking Water From One Tap
Reverse osmosis pushes water through a very fine membrane that holds back most dissolved solids. The system sits out of sight under your kitchen sink and feeds a small faucet of its own, set beside the one you already use. You get cleaner water where you drink and cook, without treating every tap in the house.
It's the right call when the worry is what ends up in your glass: a chlorine taste, lead from older plumbing, or wanting more assurance than the tap gives you. If the trouble is spots on the shower glass or stains in the laundry, a water softener or whole-home filtration is the better fit. We'll tell you that on the call instead of selling you the wrong thing.
Most of the job happens inside one cabinet. We put down drop cloths, wear shoe covers and explain any hole we need to drill before the drill comes out.
What Comes With the Install
- Multi-stage filter train
- First a sediment prefilter traps grit. Next a carbon stage removes chlorine so it can't wear out the membrane, and the membrane handles the heavy lifting. A final carbon filter cleans up the taste just before the faucet.
- Storage tank
- RO produces water slowly, so a small pressurized tank holds a ready supply. We position it so your trash can and cleaning supplies still fit.
- Dedicated faucet
- If your sink has a spare sprayer or soap dispenser hole, we can use it. Otherwise we drill a new one in the sink or countertop, and we mark the spot with you first.
- Drain connection
- The membrane rinses itself into your drain line. We connect with a proper drain saddle so waste water can't back up into the unit.
- Line to the fridge
- Want filtered water and ice from your refrigerator too? We can run tubing over to it, and we'll trace the path with you before any work starts.
- Leak check and cleanup
- We bring the system up to pressure, check every fitting and wipe out the cabinet. The drop cloths are the last thing we pick up.
Signs an RO System Makes Sense
The tap tastes like a pool
Chlorine keeps city water safe, but some people can't stand the taste. RO with carbon stages takes it out of your drinking water.
You haul bottled water home
If cases of bottles crowd your pantry, a filtered faucet at the sink puts that same quality of water within reach. No more lugging cases or filling the recycling bin with plastic.
Your home has older plumbing
Older pipes and solder can add lead to water sitting in the lines. A reverse osmosis membrane is one of the better ways to reduce it at the kitchen tap.
Coffee and ice taste off
Cloudy ice cubes or flat-tasting coffee often come from what's dissolved in the water. Many people notice a difference in the first pot.
You're on a private well
RO pairs well with well water treatment. The whole-house equipment handles iron and hardness, and RO finishes the water you drink.
How the Job Goes
- 1
The phone call
It starts with a conversation. Let us know what you notice in your drinking water and how your sink and cabinet are set up. We give you a free quote by phone, and that quote holds for 30 days.
- 2
A look under the sink
We check the space, the shutoff valve, the drain and your water pressure. If a shutoff won't close all the way, we point it out before we touch it.
- 3
Install day
Floors get covered from the door to the sink. We clear the cabinet with you, mount the system, set the faucet and connect the drain. Most kitchens are done in a few hours.
- 4
Flush and walkthrough
We run the system and dump the first tank or two so the new filters rinse clean. Then we show you how to change filters and where the shutoff is, and we answer any questions you have.

What Moves the Price
Most RO installs are close in price, but a few things in your kitchen can change the number. We go over each one on the call so your quote has no surprises. You pay in full when the install is done, and financing is available through U.S. Bank Avvance, on approved credit.
- Countertop material
- Using an existing hole costs nothing extra. Drilling quartz or granite takes special bits and more time than a stainless sink.
- System features
- A basic four-stage unit costs less than one with a remineralizing stage or a booster pump. We'll say if your pressure actually calls for a pump.
- Fridge line length
- A short run to a fridge next to the sink is simple. Going across the kitchen or through a basement ceiling adds time and tubing.
- Condition of the valves
- A stuck or leaking shutoff under the sink should be replaced before we connect anything. We'll show you the problem first.
Reverse Osmosis Questions
Something not covered here? (262) 599-6425
Does an RO system waste water?
Yes, a share of the water is sent to the drain to keep the membrane clean. The amount varies with the model you pick and the pressure coming into your home. We give you the ratio for the exact system we quote, so the water bill holds no surprises.
Will it fit with my garbage disposal?
In most kitchens it does. We set the tank and filter housings off to one side and tap the drain line above the disposal. When the cabinet is crowded, we show you the layout before anything gets mounted.
How long do the filters last?
The sediment and carbon prefilters, along with the final taste filter, usually get replaced once a year. The membrane lasts several years, depending on how much water your household goes through. Before we leave on install day, we walk you through a filter change so you can handle it yourself.
Can I run RO with a water softener?
Yes, and the two get along well. Softened water is gentler on the membrane, and the RO pulls out the sodium the softener adds to your drinking water.
What if I change my mind after signing?
You get three business days after signing to cancel. You don't pay anything until the install is finished.
