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 .

Rapid CityFrequently 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.
