Overview

About the Thirst RO — Restore™ Alkaline System

The Thirst RO Restore adds a 5th alkaline remineralization stage to the proven RO purification platform. After removing 90%+ of dissolved solids, the Restore passes purified water through a mineral cartridge that reintroduces beneficial trace minerals and electrolytes — calcium, magnesium, and potassium — raising the pH to a healthy alkaline level. The result is drinking water that's both ultra-pure and mineral-enriched, with a smoother, more natural taste than standard RO water.

How It Works

6-stage purification with remineralization

The first five stages are identical to the Thirst RO Pure — sediment pre-filtration, carbon pre-filtration, RO membrane purification, and carbon polishing. The sixth stage adds an alkaline remineralization cartridge containing natural mineral media that dissolves trace amounts of calcium, magnesium, and potassium back into the purified water. This raises the pH from the slightly acidic range typical of RO water (6.0–6.5) to a balanced alkaline level (7.5–8.5).

Included on all RO installs, the FLOWLOK Leak Detector is an innovative device that installs right below your RO water filtration system. Once the safety disc has detected water it expands and trips the FLOWLOK safety lever to shut off the water entering the water filtration device. Safety discs are replaceable and are economical.

Why choose the Thirst RO Restore

Standard RO water is extremely pure, but some people find it tastes flat or slightly bitter due to the removal of all minerals. The Restore addresses this by reintroducing trace minerals that improve taste and mouthfeel while maintaining the purity benefits of reverse osmosis. It's also the right choice if you prefer alkaline water for health reasons — the remineralization stage raises pH naturally using mineral media, not chemical additives.

Balanced hydration for Arizona's dry climate

Arizona's arid climate means residents need to stay well-hydrated year-round. Water that tastes better gets consumed more — and the Restore's mineral-enhanced, alkaline water has a smoother, more satisfying taste than standard RO water. The remineralization stage adds back the beneficial minerals (calcium, magnesium) that Arizona tap water actually has in abundance but that are removed along with harmful contaminants during the RO process.

Ideal For

Families who prefer the taste of spring water

Anyone interested in alkaline water without chemical additives

People who find standard RO water tastes flat

Health-conscious households focused on hydration

What customers say about Thirst RO

Just got an RO system installed by Shawn Parkes and I’m so happy I went with Clear Water for the install! He was extremely friendly, knowledgeable, and efficient. Would absolutely recommend Shawn and Clear Water to anybody in the San Tan Valley area looking for RO or other water solutions.

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!

Jared was very conscientious and professional. He checked our reverse osmosis system and changed the filter. He advised us what to watch for and how to prolong the useful life of our system. Thank you Jared.

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.

We had a RO system installed in our home in the Villages in Queen Creek, AZ by Clear Water Concepts. We were very happy with the quality of the unit, and with their employee Ari, who installed the system and described it’s use very clearly. He was on time and friendly, and he cleaned the space where he was working. I would definitely refer them to you. Having clean drinking water is so important. Ari tested our water from our refrigerator system and it was almost as high as our tap water!! Eek! Extra scary as we live near the golf course (pesticide..). 💯%
