Whole Home Water Filtration in Tucson, AZ

CLEANER, SAFER WATER
Water Filtration and Water Softener Installation in Tucson
Tucson’s tap water is safe to drink. It’s also extremely hard, mineral-heavy, and — depending on your neighborhood — carries enough dissolved solids to leave white scale on every surface it touches. That hardness isn’t just cosmetic. It shortens the life of your water heater, grinds through faucet cartridges, clogs showerheads, builds up inside your pipes, and makes your skin and hair feel dry no matter how much moisturizer you use.
Al Coronado Plumbing installs whole-home water softeners, whole-home filtration systems, reverse osmosis (RO) drinking water systems, and combination setups. We help you figure out which system actually solves your specific problem — because “water filtration” isn’t one-size-fits-all, especially in Tucson.
Current special: $100 off any whole-home water filtration installation.
What does the installation include?
- Free estimate. We come out, look at the house and the water, and give you a price. That is free — not a discounted diagnostic, free.
- The price in writing, before anything starts. Andrew’s standard: we tell you what it is, how much it will be, and then we keep the price exactly where we said it would be.
- Installation to the Coronado Standard. The same method, by any of our technicians, against written standards rather than individual habit.
- Home protection fitted where the job calls for it — pressure gauge, Y strainer, correct bypass.
- We stand behind the work, and then we leave you alone.
What’s in Tucson’s Water?
Understanding what’s coming out of your tap helps you choose the right system. Here’s what Tucson Water’s own reports and independent testing consistently show:
Hardness: 12 to 22 grains per gallon
The Water Quality Association considers anything above 10.5 grains “very hard.” Tucson’s water is firmly in that territory, and it’s even harder in some parts of the metro — especially areas served by blended Colorado River water.
Total Dissolved Solids (TDS): typically 300-500+ ppm
TDS includes calcium, magnesium, sodium, and other dissolved minerals. Higher TDS means more mineral content affecting taste, scale buildup, and appliance performance.
Chloramine
Tucson Water uses chloramine (chlorine combined with ammonia) as a disinfectant. It’s effective for keeping water safe through the distribution system, but some residents notice a taste or smell, and chloramine is harder to remove than free chlorine — standard carbon filters don’t fully remove it.
Other contaminants
Depending on your neighborhood and the age of your home’s plumbing, trace contaminants like lead (from older solder joints), PFAS, and other compounds may be present at varying levels.
The Tucson Water annual quality report (available from Tucson Water’s website) breaks this down in detail for your specific water source. We can also test your water on site to measure hardness, TDS, and other factors before recommending a system.
EXPERIENCE THE DIFFERENCE DAILY
What is a softener alternative, and how is it different?
A conventional system removes hardness minerals by exchanging them for sodium, which means salt, a brine tank and ongoing maintenance.
The alternative we install, NATURALSOF, works differently: a catalytic rod changes the minerals so they bind to each other rather than to your plumbing and fixtures. No salt, no brine tank, and no maintenance — it runs for at least ten years without being touched.
It is a mineral solution rather than a filtration one, so it is not the answer to every water problem. Whether it suits your house depends on what is actually in your water, which is what the free estimate establishes.
How do companies in Tucson price whole home water treatment?
Four things drive the number, and the gap between quotes usually comes down to which of them a company has included.
Installation & Materials
The equipment itself is the smallest share. What varies is the install: whether there is a pressure gauge and a Y strainer protecting the house, whether the connections are made in copper or on a flex line, whether the bypass is plumbed properly, and whether the work is to code.
Home Sizing & Layout
Then the house. Tucson’s water hardness means a system here works harder than the same unit in a soft-water region, so sizing is not a catalogue exercise. Where the main enters, how far it is from a drain, and whether there is a loop already roughed in all change the labor.
Warranty Protection
Then the warranty position — who stands behind the install, and for how long, when the manufacturer’s warranty covers only the equipment.
Contractor Type
And finally what the company is paying for: a quote from a water treatment specialist covers a salesperson and an installer. A quote from a plumbing contractor covers a licensed trade that could re-plumb the house it is working in.
Whole home water treatment and softener alternatives start at $2,163. Drinking systems, including reverse osmosis, start at $1,263.
PURE WATER RIGHT FROM YOUR TAP
Reverse Osmosis (RO) Drinking Water Systems
If your primary concern is drinking water quality, a point-of-use reverse osmosis system is the most effective option. An RO system installs under your kitchen sink and delivers purified water through a dedicated faucet.
RO filtration removes up to 99% of dissolved solids, including minerals, heavy metals, chloramine, fluoride, and most organic compounds. The result is exceptionally clean, clear, neutral-tasting drinking water.
Why RO is popular in Tucson:
- It’s the best way to deal with Tucson’s high TDS levels for drinking and cooking water.
- It removes chloramine that standard carbon filters struggle with.
- It’s a relatively affordable upgrade — much less than whole-home systems — and the filters last 6 to 12 months depending on usage.
- Many Tucson homeowners use an RO system in combination with a whole-home softener: the softener protects the plumbing, and the RO provides clean drinking water.
We install under-sink RO systems and connect them to your existing cold water line and a dedicated RO faucet. Some homeowners also connect the RO output to their refrigerator’s ice maker and water dispenser.
What Our Customers Say
Don’t want you to take our word for it. See what people in your neighborhood are saying about Al Coronado Plumbing.
Brandon of Al Coronado Plumbing provided me with a detailed estimate and explanation of the reverse osmosis water system he recommended. After consulting with two other companies, I decided Al Coronado Plumbing would be best (type, cost and installation) for this project. This truly is a great company.
Luke, the technician, came out to replace the filters in our water filtering system. He also needed to replace the carbon filter—this meant that our system needed to be bypassed for a few days. He called with an apology for being late with the replacement filter and tank as he had a family emergency. He promptly came out the next day and put everything together—everything worked well and the water tastes great. Luke was very polite and knowledgeable about the system, and made sure that I understood the process and was okay about it. He is an asset to their company.
Marty was a pleasure to work with: knowledgeable, efficient, and, most importantly, took the time to explain everything I’ll need to know to replace whole house water filters in the future.
Marty assessed and gave an estimate, then Gabriel arrived on time and finished the work beautifully in under two hours. Marty followed up to ensure we were happy. Al Coronado is our plumber of choice!
Best experience—repairs done professionally and on time. Kevin K and Robert were extremely knowledgeable with great attention to detail. Thank you!
We had several small issues—Marty and Gabriel gave clear options, worked neatly and quickly, and everything was completed on time. They’re now our go-to plumbers.
Charlie came for an estimate—friendly, extremely professional, and very informative. Because of her service, we’ll definitely call again. Thanks, Charlie!
They showed up on a Sunday with less than 24 hours’ notice and fixed our problem. Xavier was professional, kind, and explained everything. Absolutely recommend!
PURE DRINKING WATER SOLUTIONS
Why does Al Coronado cost more than a $1,200 quote?
Because the two quotes are not for the same thing, and the difference is almost entirely in what happens after the van leaves.
- The install standard. Every repair at this company is done the same way by every technician, against written standards — what Andrew calls the Coronado Standard. Most companies give you the plumber you happen to get and the workmanship that plumber happens to have.
- Home protection on the install. Pressure gauge and Y strainer where the job calls for it, rather than a tank on a flex line.
- Equipment chosen on evidence rather than on a sales pitch. Our systems are built to our specification — the tank from whoever makes the best tank, the valve from whoever makes the best valve — rather than bought as a package from whichever manufacturer has a rep in the area.
- Forty-five years of knowing what fails. Andrew’s words: we install what we are positive works, because it has worked thousands of times before.
- Technicians trained in-house, to a curriculum, continuously.
A $1,200 whole home quote is possible. It just tells you which of those five it has removed.
How Water Treatment Protects Your Plumbing
This is the angle most people miss. Water treatment isn’t just about taste and convenience — it’s about protecting the plumbing infrastructure you’ve already invested in:
Water heater lifespan
Softened water dramatically reduces sediment buildup inside your tank, meaning less stress on the heating element and a longer-lasting unit. In Tucson, this can mean the difference between replacing your water heater at 8 years versus 12+.
Faucet and fixture longevity
Hard water grinds through cartridges, valves, and seals. Homeowners with softened water replace faucet components far less often.
Drain and pipe health
Mineral scale narrows pipes over time. Softened water stops that accumulation and can even allow existing scale to gradually dissolve.
Appliance efficiency
Dishwashers, washing machines, and ice makers all perform better and last longer with treated water.
HEALTHIER WATER, HEALTHIER HOME
One phone call
Andrew’s standard for his own company, in his own words: when a customer calls with a problem, they should make one phone call and have the problem go away.
“We will answer the phone. We will return your phone call. We will come out for free. We will tell you what’s up, how much it’s going to be. We will do the job exactly the way we said we would. We will keep the price exactly where we said. We will stand behind our work, and we will leave you alone to live your life.”
If any one of those steps is missed, you can speak to the ownership of the company and we will make it right.

Frequently Asked Questions
How much does whole home water treatment cost in Tucson?
Whole home water treatment and softener alternatives start at $2,163. Drinking systems, including reverse osmosis, start at $1,263. What moves a job above the starting figure is the install — where the main enters, how far it is from a drain, and what home protection the house needs. The estimate is free and the price is in writing before work starts.
What is the difference between a water softener and a softener alternative?
A conventional system exchanges hardness minerals for sodium, which needs salt, a brine tank and ongoing maintenance. The alternative we install uses a catalytic rod to change the minerals so they bind to each other instead of to your plumbing. No salt, no maintenance, and a service life of at least ten years.
Do you install reverse osmosis drinking systems?
Yes, starting at $1,263. A drinking system treats water at one tap rather than throughout the house, so it is often fitted alongside whole home treatment rather than instead of it.
Is the estimate free?
The estimate is free. If a diagnostic is genuinely needed — crawling an attic, tracing a problem that is not visible — that is chargeable, and we will tell you before we do it. Some companies blur those two; we do not.
How soon can you come out?
Same day in most cases, including emergencies. We will not promise you a thirty-minute window, because nobody can deliver one honestly. Same day we can.
Do you charge more for emergency or after-hours work?
The price of the job is the same whatever the day or hour. Call (520) 834-8400.
Why should a plumber install my water treatment rather than a water treatment company?
Because it is plumbed into the water your household drinks. A plumbing contractor is licensed for the trade, knows the code, and can re-plumb the house it is working in. A water treatment installer knows one product.
How long has Al Coronado been doing this?
Since 1981 — forty-five years in Tucson. That matters here specifically because it means we have installed the systems that failed as well as the ones that lasted, and we install the ones that lasted.
