Reverse Osmosis in Coronado, CA.
Reverse Osmosis for Coronado homes, done by licensed San Diego County technicians. Reverse osmosis forces water through a semi-permeable membrane that rejects dissolved contaminants: dissolved solids, nitrates, heavy metals, PFAS compounds, sodium, and more. The result is water that consistently outperforms bottled water in purity and does it for pennies per gallon rather than dollars.
What reverse osmosis looks like in Coronado
An under-sink RO system at the kitchen tap reduces TDS, removes chloramine, and delivers remineralized drinking water that's a noticeable improvement over straight Coronado tap water. At 17-20+ grains and with chloramine disinfection, the tap water here has a flat, slightly chemical character that most residents are aware of. RO removes dissolved solids near completely and the remineralization stage adds beneficial minerals back for taste. For older Village homes, RO at the kitchen tap also serves as a final polishing stage against anything that might be contributed by aging supply lines.

How does Coronado's climate affect this service?
Coronado is a peninsula surrounded by the Pacific and San Diego Bay. Salt-air exposure affects every parcel. Municipal water is very hard and chloraminated. Stainless steel equipment is essential for longevity in this environment. Older homes in the Village are candidates for whole-home treatment that protects legacy plumbing. An under-sink RO system at the kitchen tap reduces TDS, removes chloramine, and delivers remineralized drinking water that's a noticeable improvement over straight Coronado tap water.
Does reverse osmosis remove PFAS?
Yes. Reverse osmosis is one of the most effective technologies for PFAS reduction. The EPA established enforceable drinking water limits for several PFAS compounds in 2024, and NSF/ANSI 58 certified RO membranes are rated for PFAS reduction. We specify certified membranes on every RO install.
Does RO remove beneficial minerals?
RO removes most dissolved minerals, including calcium and magnesium. Some people prefer to add a remineralization stage after the membrane that reintroduces trace minerals and slightly raises the pH. We offer this as an add-on. For most households the difference in mineral intake from water versus food is negligible.
