Reverse Osmosis in La Presa, CA.
Reverse Osmosis for La Presa 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 La Presa
La Presa tap water carries the dissolved minerals and chloramines that characterize East County's inland municipal supply, and a whole-house conditioning system doesn't reduce total dissolved solids at the drinking tap. An under-sink reverse osmosis system at the kitchen faucet addresses that directly, reducing TDS, chloramines, and PFAS to near-bottled-water levels. For households in the Worthington Street and La Presa proper neighborhoods that currently buy bottled water, the RO pays for itself over time.

How does La Presa's climate affect this service?
La Presa is unincorporated East County between Spring Valley and Bonita with hard municipal water and hot inland summers. The 1960s-90s residential stock shows the typical East County pattern of scale on fixtures, shortened water heater life, and dishwasher deposits that come with untreated hard water. La Presa tap water carries the dissolved minerals and chloramines that characterize East County's inland municipal supply, and a whole-house conditioning system doesn't reduce total dissolved solids at the drinking tap.
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.
