Reverse Osmosis in Granite Hills, CA.
Reverse Osmosis for Granite Hills 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 Granite Hills
Whether you're on the municipal supply or a private well, Granite Hills drinking water benefits from a dedicated under-sink reverse osmosis system at the kitchen tap. The RO membrane and post-carbon stage reduce total dissolved solids, chloramines (on city water), iron and sulfur carry-through (on well water), and PFAS to near-bottled-water levels. For well customers dealing with multiple contaminants, the RO serves as the final polish after the whole-house system handles the bulk of the treatment upstream.

How does Granite Hills's climate affect this service?
Granite Hills is semi-rural East County foothills with some of the hardest water in the county and significant private well inventory. Municipal customers face very hard water with aggressive scale. Well customers on the upper slopes and rural edges deal with iron, sulfur, sediment, and hardness in combination. Inland summer heat over 100°F makes scale accumulation in appliances worse. Whether you're on the municipal supply or a private well, Granite Hills drinking water benefits from a dedicated under-sink reverse osmosis system at the kitchen 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.
