Reverse Osmosis in Lake San Marcos, CA.
Reverse Osmosis for Lake San Marcos 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 Lake San Marcos
Hard water at 17-22 gpg tastes mineral-flat at the drinking faucet and in coffee, and the chloramine used in San Diego municipal water produces an off-taste that does not go away by letting the water sit. Our five-stage under-sink RO system at the kitchen faucet removes both, producing water that tastes neutral and clean. For the Lake San Marcos Country Club and golf-course-adjacent homes where residents entertain regularly, consistently clean-tasting drinking water matters beyond basic filtration.

How does Lake San Marcos's climate affect this service?
Lake San Marcos draws municipal water from the greater San Marcos supply with moderate to moderately high hardness, typical of North County Inland supply zones. Older plumbing in the community's 1960s-70s era homes is a secondary concern, and the lake community lifestyle means residents notice water quality in skin, hair, and drinking water. Hard water at 17-22 gpg tastes mineral-flat at the drinking faucet and in coffee, and the chloramine used in San Diego municipal water produces an off-taste that does not go away by letting the water sit.
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.
