Whole-Home Filtration in Oconomowoc
We mount one filtration system on the main supply line, so every faucet, shower and appliance in your home draws filtered water. We take photos of your plumbing before we start, partway through and once it is done, so you can see exactly what went in.

Filtered water from every faucet, not just one
A whole-home filter sits on your main water line, usually near the meter or pressure tank. Most setups use two stages. A sediment filter stops sand, grit and loose scale first, and a bed of activated carbon after it pulls out chlorine along with the odor and flat taste it leaves behind. Everything downstream gets the benefit.
It makes sense when the problem turns up all over the house: a chlorine smell in the shower, grit in faucet screens, or water that tastes off at the bathroom sink as much as the kitchen. When the only water you care about is what you drink and cook with, an under-sink reverse osmosis system can be a smaller and less costly project. We will be straight with you about which one suits your home.
Plenty of homes around Oconomowoc already have a softener in the basement. Carbon filtration does different work than a softener, and we plan the order of the two so each one protects the other.

What your installation includes
- 01
A look at your main line
We check where the water comes in, the pipe size and material, and how much room there is to work. We photograph it so you can see the starting point too.
- 02
Sediment prefilter
A first stage that traps grit and particles before they reach the carbon. That keeps the carbon working longer and keeps sand out of your fixtures.
- 03
Carbon filtration sized to your home
We match the system to your flow needs, based on bathrooms, people and how often several taps run at once. An undersized filter can drop pressure in the shower, so we size it to avoid that.
- 04
Bypass valve and shutoffs
A bypass lets you keep water running to the house while a filter is changed or serviced. Shutoffs on both sides make future work simple.
- 05
Flush, leak check and walkthrough
We flush the new media, check every joint for leaks and show you around the finished setup. You keep the before, during and after photos.
Questions about Whole-Home Filtration?
Call(262) 440-9237Signs your home could use whole-home filtration
The bathroom smells like a pool
Chlorine leaves hot water as it turns to steam, which is why a closed bathroom can smell strongest right after a shower. Carbon on the main line removes it before it ever reaches the showerhead.
Grit in aerators and screens
If you keep unscrewing faucet aerators to rinse out sand or flakes, or the washing machine inlet screen clogs, a sediment stage helps.
Every tap tastes a little off
A fridge filter or pitcher only fixes one spot. When you notice taste at the bathroom sink too, the fix belongs on the main line.
A softener with no filter ahead of it
Chlorine and sediment can wear on softener resin over time. A filter placed correctly in front of it can help the softener last.
Old equipment nobody explained
You may have moved in with housings and tanks in the basement and no idea what they do. We can look it over and tell you honestly whether to keep, repair or replace it.
How the job runs

Phone call and free quote
Tell us what you are noticing and where. We set a time to come out and look at your plumbing.
- 2
Home visit and written quote
We photograph your main line and explain the options in plain terms. Your quote holds for 30 days, so there is no rush to decide that afternoon.
- 3
Installation
On the scheduled day we turn off the main, plumb the new system into the supply pipe and add the bypass and shutoffs. Drop cloths go down wherever we are working. Water to the house is off for only part of the visit.

Finish and payment
We flush, check for leaks, show you how to change filters and hand over the full set of pictures. Full payment is due when the install is complete, not before.
What affects the price
Every home is a little different, so we quote after seeing your main line instead of guessing over the phone. Here is what moves the number. Financing is available through U.S. Bank Avvance, on approved credit.
- Cartridge or tank system
- Cartridge housings cost less to start but need more frequent changes. Larger carbon tanks cost more up front and go much longer between service.
- Size of your home and flow
- More bathrooms and more people mean more water moving at once, which calls for a larger system to keep pressure steady.
- Access to the main line
- An open basement wall is quick work. A finished basement, tight utility closet or crawlspace takes more time.
- Pipe condition and existing equipment
- Corroded valves or old fittings near the meter may need replacing. Fitting the filter around an existing softener can add some plumbing too.
Whole-home filtration questions
Will filtering the whole house cut my water pressure?
Not if the system fits your home. A drop you can actually feel usually points to a filter that is too small or a cartridge that is clogged and overdue. We size yours to how much water your household moves at once, and we show you when each cartridge should be swapped.
Does this replace my water softener?
No. Carbon filtration handles chlorine, taste, odor and sediment, while a softener handles hardness minerals. Many homes run both, and we can explain how they work together or talk through water softeners separately.
Do I still need reverse osmosis for drinking water?
That depends on what you want from your kitchen tap. For a lot of households, carbon-filtered water tastes clean enough that they stop there. If you would like one more layer for the water you drink and cook with, an under-sink reverse osmosis system is a common add-on.
How often do the filters need changing?
It depends on the system and how much water your home uses. Sediment cartridges often need changing a few times a year, while larger carbon tanks last much longer. We give you a simple schedule for your setup.
We have a private well. Is this the right system?
Sometimes, but wells can bring issues like iron or a sulfur smell that a carbon filter alone will not solve. Our well water treatment page covers those systems, and we will tell you which approach fits when we visit.
What if I change my mind after signing?
You have three business days after you sign to cancel. Your quote also holds for 30 days, so you can take time to think it over first.
