Reverse Osmosis Systems
Reverse Osmosis Systems in Sunnyvale
Kitchen RO for homes and condos across Sunnyvale, installed in about two hours.

What RO adds to Sunnyvale tap water
Reverse osmosis systems in Sunnyvale push water through a semi-permeable membrane that rejects most dissolved solids and many contaminants that carbon alone cannot remove. The result is drinking and cooking water with very low TDS and no chloramine taste.
It is popular with households that buy bottled water, coffee and tea enthusiasts, and families who want an extra barrier for what they drink. The membrane needs protection from chloramine, so we pair it with catalytic carbon pre-filters rated for it. That one detail is the most common reason RO systems underperform in the Bay Area.
Some people find RO water tastes almost flat because the minerals are gone. A remineralizing stage puts a little back. We bring a sample so you can decide before we install.
RO also pairs well with a whole-house carbon or softener system. With the main line already treated, the RO pre-filters last longer and the membrane works less hard. We note those savings on the spec sheet when both systems are installed together.

What the RO install includes
A finished drinking-water station, plumbed and tested.
TDS and chloramine readings
Measured before so we can prove the improvement after.
Sediment and catalytic carbon pre-filters
Protects the membrane from chloramine damage.
Certified membrane
Sized to your daily drinking and cooking volume.
Tank or tankless configuration
Tankless where cabinet space is tight, tank where steady output matters.
Dedicated faucet
In an existing hole or a clean new one in the sink or counter.
Drain saddle and air gap
Installed correctly to prevent backflow.
Optional refrigerator line
Ice and dispenser water from the RO.
Sanitize and flush
So the first glass is a good one.
How an RO install goes
-
Measure and check the cabinet
TDS and chloramine readings, a look at the sink and drain, and a spec sheet with waste ratio, membrane life and price.
-
Install
Filters mounted, faucet fitted, drain saddle and supply connected, leaks checked. About two hours.
-
Compare the numbers
TDS at the new faucet next to TDS at the tap, so you see what the membrane does.
