What Oro Valley Homeowners Say

Reviews from Oro Valley and nearby Tucson-area homeowners

Reliable and knowledgeable company. Our home is in Oro Valley. Mike did a fantastic job, arriving on time and explaining how the RO system worked. He examined my soft water system as well. He said an 18 month filter replacement was all that is needed, based on our water usage and filter particle accumulation. I will keep using them.

I cannot say enough good things about Clear Water Concepts/Absolute Osmosis! We live in North Tucson, where the water is extremely hard, so we shopped around and looked at several different companies before making our decision. Our sales representative, Moses, was excellent. He took the time to explain all of our options and discuss the different types of systems available on the market so that we could make a truly informed decision. At no time did we feel pressured to purchase anything, unlike some of the other companies we considered. The installation was exceptional as well. If you live in Tucson or surrounding area, ask for Mike as your installer! He has years of experience and took his time to make sure everything was done perfectly. I honestly don't think I've ever seen a plumber use a bubble level before—but Mike made sure every pipe was precisely level and professionally installed. He also carefully sealed any wall penetrations that were necessary and left the work area cleaner than it was when he arrived. After the installation, Mike took the time to thoroughly walk us through both our water softener and reverse osmosis systems to make sure we understood how everything worked. If you are looking for a stress-free experience purchasing and installing a water softener and/or reverse osmosis system, I highly recommend Clear Water Concepts/Absolute Osmosis. From the sales process to the installation, the entire experience was outstanding!

My reverse osmosis needed to be replaced. Clearwater had been changing the cartridges in the RO system, and when I called, they came out to inspect, and recommended a new unit based on the current condition of mine. I got a quote right away with discounts that they applied because I’ve been their customer in the past. The work then got scheduled. Mike showed up right on time and completed the installation in no time at all, very professional he was. Cleaned up after himself and put it in a position under the sink that made the area more usable. I was very happy and satisfied with the work that was done. And definitely recommend Clearwater.

Michael the tech was a little behind on arrival time but not his fault. Called to let me know that they had dispatched to a different address as i live in Rancho Sahuarita.When he arrived he explained the process of installing the equipment and got right to work. Michael did an excellent job explained how the Softener and the RO system worked . Thank you Michael and Clear Water Concepts for your excellent service and thank you Kyle for recommending this new system.

Common questions about reverse osmosis in Oro Valley

How hard is the water in Oro Valley?

Oro Valley water hardness averages 12-18 GPG, sourced from groundwater + cap. This is significantly harder than the national average of 6 GPG, meaning scale buildup, dry skin, and appliance damage are common without treatment.

How much does a reverse osmosis system cost in Oro Valley?

Reverse osmosis systems for Oro Valley homes start at $795: Thirst RO Pure from $795, Thirst RO Restore from $895, Thirst RO Thrive from $995.

Pair with a water softener and save $350 with our bundle deal. 0% APR financing for 9 months is available.

Do I still need reverse osmosis if I have a water softener?

Yes, for drinking water. A softener removes hardness so your pipes and appliances last, but it does not remove dissolved solids, chlorine, or other contaminants. Reverse osmosis handles the water you drink and cook with — most Oro Valley homes pair both, and the bundle saves $350.

Oro Valley tap water contains Hardness, chlorine, moderate TDS. A Thirst RO system removes 90%+ of dissolved solids and contaminants, and the RO+ model adds alkaline remineralization for better-tasting water.

Where does a reverse osmosis system install?

Under the kitchen sink, with its own dedicated faucet at the counter. Installation is quoted separately for every RO system we sell in Oro Valley.

Arizona's high dissolved-solids water works filters harder than the national average. Pre-filters are typically replaced yearly and the membrane every few years — we set a schedule based on your Oro Valley water and household usage.

Do you offer financing on reverse osmosis systems in Oro Valley?

Yes — 0% APR financing for 9 months applies to reverse osmosis systems installed in Oro Valley, and pairing RO with a water softener saves $350.
