Reverse Osmosis in Crest, CA.
Reverse Osmosis for Crest 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 Crest
Even after whole-house treatment, some Crest residents want bottled-quality water at the kitchen tap for drinking and cooking. An under-sink RO system removes what whole-house filters are not designed to target: nitrates, any trace heavy metals, and residual dissolved solids that affect taste. Well water in the Crest area can carry dissolved minerals at levels a whole-house system conditions but does not fully remove. RO reduces TDS to near-zero at the drinking tap.

How does Crest's climate affect this service?
Crest sits at 1,500 feet on a ridge east of El Cajon with hot summers and winter freeze nights. Almost all homes are on private wells. Groundwater in this area typically runs hard with dissolved iron and can have low pH, producing the same staining and scale problems common across East County foothill well systems. Even after whole-house treatment, some Crest residents want bottled-quality water at the kitchen tap for drinking and cooking.
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.
