Reverse Osmosis Drinking Water Systems

Tired of foul taste, hard-to-remove contaminants, or bottled water waste? Our Reverse Osmosis (RO) systems deliver purified, great‑tasting water straight from your kitchen—without the fridge clutter or constant supply runs.

Perfect Together with Watertree Solutions

An RO system fits into the broader Watertree lineup—paired with our water softeners, whole‑home filters (for sediment or iron), and even our bottled‑water delivery and dispensers for ultimate water coverage.

What Is an RO Drinking Water System?

A typical under-sink RO system sends water through multiple filters—sediment, carbon filters, then a semi‑permeable membrane that blocks 95–99% of contaminants like chlorine, lead, mercury, fluoride, PFAS, and other dissolved solids.

It then stores the purified water in a pressurized tank, ready whenever you are .

Benefits of RO at a Glance

Removes the Tough Stuff

Heavy metals, minerals, and “forever chemicals” get scrubbed out.

Great Tasting Water

No chlorine, no odors—just pure refreshment.

Convenience & Savings

No more lugging bottles; system typically pays for itself within a couple years vs. bottled water.

Low Maintenance

Replace filters every 6–12 months, membrane every 2+, and you’re good to go.

I went in to get a part for my pool. They didn’t have it but the guy checked around town for me to see if anyone else did.

Frequently Asked Questions

Under-sink units typically waste 3 gallons for every 1 filtered—tankless units can be more efficient. But compared to bottled water savings, it’s still minimal.

Yes—it removes calcium and magnesium. We can install a remineralization filter to restore beneficial minerals for taste and health.

Probably not. Whole-house RO is costly, wasteful, and needs massive tanks. For drinking and cooking, under-sink RO is smart, affordable, and efficient.

Filters need changed every 6–12 months, membranes every 2–3 years, and tanks/tubing last a decade—then replacement is minimal.
