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

Had a soft water and RO system installed on 7/31/2026. Jace was my Tech. Appointment was for 8:30am he was at my house at 8 am which was perfect. He was professional, Friendly and explained everything he was going to do and he went over everything after he was done. It took him 2 1/2 hour to install both systems. I'm very happy with my purchase.

Our water softener and RO system install was done very well by our technician Jace Rhude. He explained everything for both systems and how to best maintain everything and when to change the RO filters. I would recommend Clear Water Concepts for all of your water treatment needs for Casa Grande AZ. Thank for your great service!

today Clearwater installed new RO unit and a whole house water softener. And they installed a water bib and line to my backyard. I am beyond satisfied. What is superb Crew they sent, three guys each superb. I am so happy no shortcut they put copper tubing in everywhere and buried at 12 inches deep right the code. I’ll tell you it’s a joy and outright joy to have someone that you can depend on and I’ll tell you what from now on I am with this company and hopefully they send the people again. My Salesman Joshua came out was superb and presentation and so a good quality out. We are happy we are well pleased. And they RO is five year warranty and a water softener 10 year. I 79. Not sure I’ll be here, ha,. I am just delighted wonderful!!!
