Whole-Home Water Filtration in Phoenix
The decision on house water is whether to treat one tap or the pipe that all taps share. What settles it is what you are trying to be rid of, because a chlorine smell that reaches the shower and the laundry is a different job from the taste of one glass at the kitchen sink, and neither of those is what a softener does.
Whole-home filtration can pair a sediment stage for particle removal with a carbon stage for chlorine taste and odor. Pavel Farcas (Paul) settles where the housings sit: on the cold main line, somewhere the afternoon sun won't bake them.

“The water smells like bleach.”
Carbon is the stage that handles it.
The City of Phoenix disinfects its whole supply with chlorine and notes that the chlorine can affect taste and odor. Pentair's whole-house system uses carbon to remove chlorine taste and odor and reported a 95.93 percent reduction in chlorine during testing.
“There's grit in the faucet screens again.”
Sand and scale flakes, strained out up front.
A sediment cartridge strains out sand and scale flakes before they reach the carbon or your fixtures. Pentair's system uses a 5-micron sediment filter ahead of the carbon. One catch: grit that comes from the water heater itself forms downstream of a main-line filter, so if the specks show up only on hot taps, the heater needs a flush first.
“Why does our water taste musty in the late summer and fall?”
A seasonal taste: algae in the canals.
Phoenix traces that musty taste and odor to algae growing in the canals that carry surface water to its treatment plants, stronger toward fall. Taste and odor reduction is one of the claim areas under NSF/ANSI 42, so if this is your main complaint, look for that claim on the product's certification listing.
Where Carbon and Sediment Stop
Will carbon handle my city's disinfectant?
Read the certification, not the box
NSF/ANSI 42 covers aesthetic claims such as chlorine, taste, odor, and particulates. NSF/ANSI 53 covers health-related claims, such as lead and VOCs, and offers more than 50 contaminant-reduction claims in all. NSF notes that claims vary by product, so a filter certified under 42 for chlorine taste has not been certified for particulates unless that claim is on its listing as well.
Water that has to be safe first
Pentair's manual says not to use its whole-house carbon system on water that is microbiologically unsafe or of unknown quality without disinfection. A carbon and sediment filter is for taste, smell, and grit on water that is already safe.
Phoenix and Scottsdale both disinfect with chlorine. Some utilities use chloramine instead, a compound of chlorine and ammonia, and standard carbon is slow to break it down. Calgon Carbon markets its catalytic carbon for its ability to decompose chloramine faster than standard activated carbon. Any provider names its disinfectant in its yearly water quality report, so check yours if you are outside those two cities.
Filtration Work We Handle

Service and upgrades
The order water passes through
Particles come out before carbon, then the water moves on to a softener or conditioner, and finally to the water heater. Each stage protects the one after it.
How We Put a Whole-Home Filter In
Describe the smell, taste, or grit
Which of the three is it, and who sends your water bill? Ring (602) 883-2787 with both.
Media picked, housings chosen
Sediment, carbon, or both, in cartridge housings or a media tank, matched to your main line and to what bothers you.
Housings mounted on the cold line
The housings are fastened to the wall and plumbed into the main line ahead of any softener and the water heater.
First water goes to a hose
Fresh carbon sheds fine black dust, so the first water through it runs out a hose until it clears, before the house goes back on it.

What Whole-Home Filtration Costs in Phoenix
A quote is free, and it lists the housings, media, and plumbing in writing before any work starts. The $75 service fee applies only when a visit ends without work.
Plan on at least one cartridge change a year; heavy grit shortens that.
Two Setups We Come Across
A filter nobody has changed in years
Pressure has dropped at every tap, and the cartridge is brown or black.
The fix is a fresh cartridge and a look at the housing and O-ring, which can flatten and weep after years under pressure.
Carbon installed after the softener
The order is backwards when chlorine reaches the resin first.
Purolite, a resin maker, says chlorine attacks softener resin, so the carbon belongs upstream. Moving it is a plumbing change we can price.

Filtering Phoenix Water: The Local Details
What the city itself says
Phoenix keeps a chlorine residual of about 1 part per million, and its 2025 report shows a range from under 0.24 to 1.9. Federal rules require at least 0.2 ppm in water leaving a treatment plant and cap it at 4 ppm in the pipes, so some chlorine at your tap is there by design. The city says its water meets or exceeds standards and that filters are typically unnecessary unless your physician advises one or you want one. So whole-home filtration is about how the water smells and tastes, and what it leaves in your fixtures.
The city's own taste tips
Before anyone buys equipment, Phoenix suggests adding a slice of lemon or leaving a container of water uncapped for 30 to 60 minutes, then chilling it in the refrigerator. Its list ends with a filter on the faucet or the refrigerator.
Cold water only
Pentair's whole-house carbon system is for cold water only, rated 36 to 120°F, and Pentek rates its Big Blue housings for 40 to 100°F. That is why the filter sits upstream of the water heater, and why a garage wall out of the sun beats a west-facing outside wall.
Pentek also recommends protecting its housings from freezing to prevent cracking and leaks, so a housing on an exposed outside wall gets insulation; our softener repair page includes the Valley's freeze numbers.
Deciding How Much Filter You Need
Whole home, or one tap
If the only complaint is the taste of a glass of water, a filter at the kitchen faucet or the refrigerator may be enough. If the smell reaches the shower and the laundry, whole-home filtration is the one that covers it.
When a media tank is worth it
Cartridge housings are the simpler setup and take a fresh cartridge on schedule. A tank-style carbon system is a larger install that runs longer between media changes; Pentair calls for new carbon after five years.
Grit only? Start with sediment
If grit is the only complaint and the chlorine smell never bothered anyone, a sediment stage by itself may be all the house needs. Add carbon when taste and smell are part of the problem; it is easier to plan both housings on day one than to re-plumb for a second later.
Whole-Home Filtration FAQs
Still have a question? Call Pavel (Paul) directly and get a straight answer, no phone tree.
Yes, any time water flows. Keep the valves set to filter except during a cartridge change, or the house gets unfiltered water.
Pentair gives its sediment filter 6 to 12 months, depending on how much sediment the water carries. The heavier the grit, the sooner it clogs.
Inside the house, no. The residual does its job as it passes through the city's pipes to yours, and the carbon takes it out after the water arrives. A hose bib plumbed ahead of the filter still delivers chlorinated water.
Yes. Pentek rates its Big Blue housings to 100 psi in the 10-inch size and 90 psi in the 20-inch. Pentair's whole-house carbon system lists a working range of 20 to 125 psi. If your house pressure runs higher than a housing's rating, the regulator is the first fix; our pressure regulator page covers it.
Your provider's yearly report is the starting point, and a certified lab can test for anything specific you are worried about.
No. Carbon and sediment handle taste, smell, and grit. An under-sink reverse osmosis unit lowers the dissolved minerals in drinking water, which is a different job.
No. Calcium and magnesium pass straight through carbon and sediment media. Scale is the job of a softener or a salt-free conditioner, and salt-free is the one American Discount Plumbing recommends; our salt-free conditioner page explains what it does and what it leaves alone.
Yes, on most cartridge housings. Put the system on bypass, or close the main shutoff if there is no bypass, then press the pressure-release button if the housing has one and loosen the housing with its wrench. Check the O-ring and replace it if it is flattened or cracked. If you would rather not, we change them for you.
