Reverse Osmosis Systems in Brookfield
We install under-sink reverse osmosis so the water you drink and cook with comes from its own faucet, cleaner and better tasting. We plumb it the safe way, with a proper drain air gap and a careful leak check, and leave your kitchen the way we found it.
What a reverse osmosis system does for your kitchen
Reverse osmosis lives under your kitchen sink. Water passes a sediment filter, then a carbon filter, then a very fine membrane. The clean water waits in a small tank and comes out of its own faucet next to your main one.
This is the right pick when your main concern is the glass of water on the table and the pot on the stove, and the other taps in your home can stay as they are. Families lean on it for coffee, ice, soup and baby formula. Others ask for it because the pipes in the house are getting old. It takes out a long list of dissolved solids and trace metals at the one spot where you fill a glass.
It will not fix the whole house. For odor in the shower or spots on fixtures, look at whole-home filtration or a water softener instead. Those treat the water before it reaches every tap.
What we do on every RO install
- Filter unit and tank, mounted right
- Housings, membrane and tank go in level, with clear access to the shutoff. You should be able to change a filter without pulling everything out of the cabinet.
- Its own faucet
- Your drinking faucet goes into a spare hole in the sink or a fresh one we drill. Stone counters get the proper bit and a slow, steady pace to avoid cracks and chips.
- A real shutoff on the feed
- We connect to the cold line with a proper shutoff valve. Self-piercing saddle valves are a known cause of slow leaks, so we leave them out.
- Drain air gap
- The waste line ties into your sink drain through an air gap. That keeps drain water from ever reaching your drinking water, and it is the step quick installs tend to skip.
- Sanitize, flush and check for leaks
- Housings get sanitized and the new filters and membrane get flushed. We check each fitting under pressure, then check again once the tank is full.
- Optional fridge or ice line
- Want filtered ice and cold water from the refrigerator door too? We can run a line over to it.
When reverse osmosis is worth it
Bottled water is a weekly chore
Cases piling up by the door add up fast. An RO faucet ends the trips to the store and the lugging from the car.
Your water tastes like chlorine or metal
Off flavors are easiest to notice in plain water and coffee. The carbon stage in an RO system removes most of them.
The pipes in your home are old
Houses built decades ago may still have lead solder or aging fixtures somewhere in the supply. An RO system adds a second line of defense at the faucet you drink from.
Scale on your kettle and glassware
White crust on a kettle or coffee maker comes from dissolved minerals. RO pulls most of those out of your drinking water.
Your water comes from a well
Many well owners want an extra step for drinking water. We match RO with the right whole-house setup, which our well water treatment page covers.
How install day goes
- 1
First, a phone call
Tell us about your sink, how much room is in the cabinet and what you want changed about your water. You get a free quote and an explanation of how financing works.
- 2
Cover and clear the area
Drop cloths go down and we move everything out from under the sink. The cold water gets shut off before we loosen a single fitting.
- 3
Put it all in
We install the valve, faucet, air gap, filters and tank. Tubing gets cut square, pushed all the way in and routed clear of the disposal and hot water lines.
- 4
Flush, watch and hand it over
We run the first flush and keep an eye on every joint. Then we show you the shutoff and the filter change, put your things back and clean up.
What changes the cost of an RO install
Most reverse osmosis installs look alike, but a handful of details push the number up or down. We go over each one by phone before you decide, so nothing shows up later as a surprise. Your quote holds for 30 days. If you would rather spread out the cost, U.S. Bank Avvance offers financing on approved credit, and full payment is due when the install is done.
- Which unit you choose
- A basic four-stage system is the low end. Units with a remineralizing stage, a bigger tank or a tankless design cost more.
- Counter material
- If there is already a spare hole in the sink, the faucet goes in fast. Stone like granite or quartz needs a special bit and a slower hand, which adds time.
- Lines to the fridge or ice maker
- A filtered line to the refrigerator means more tubing, more fittings and more labor. A long run across the kitchen or through a basement ceiling adds to that.
- The water going in
- Very hard water shortens the life of an RO membrane. In that case we may point you to a water softener upstream so the membrane holds up longer.
Common questions about reverse osmosis
Something not covered here? (262) 924-3821
How often will I change filters?
Plan on new pre-filters roughly once a year. The membrane lasts several years in most kitchens. Heavy use or rough water shortens both. We show you the swap on install day so you can do it yourself.
Will RO water taste different?
A lot of people say it tastes cleaner and a bit lighter, since most minerals are removed. If you miss the mineral taste, we can add a stage that puts some calcium and magnesium back into the water.
Does the system send water down the drain?
It does. The membrane flushes itself by sending part of the water to the drain. Newer units waste a lot less than older designs, and we can go over the choices on the phone.
What is the air gap for?
The RO waste line empties into your sink drain. If that drain ever backs up, the air gap stops dirty water from being pulled toward the water you drink. Every system we put in gets one.
What if I change my mind after signing?
You can cancel. You have three business days after you sign.
