Under-Sink Reverse Osmosis Installation in Hanford
The City of Hanford's municipal drinking water is drawn from deep groundwater wells that naturally carry elevated levels of total dissolved solids (TDS), nitrates from Central Valley agricultural activity, arsenic, and chloramines used for disinfection. A multi-stage under-sink Reverse Osmosis (RO) drinking water filtration system provides the ultimate point-of-use purification for your kitchen. By forcing tap water through a semi-permeable membrane at microscopic levels (0.0001 microns), RO systems eliminate up to 98% of dissolved minerals, heavy metals, and chemicals, delivering pure, crisp drinking and cooking water directly to a dedicated designer faucet.
Up to 98% TDS Reduction
Multi-stage filtration strips nitrates, arsenic, lead, microplastics, and dissolved calcium, leaving water exceptionally pure.
Dedicated Designer Faucets
Lead-free designer air-gap faucets matched to your kitchen sink finish (brushed nickel, matte black, chrome) prevent drain cross-contamination.
Refrigerator & Ice Maker Tie-In
We can run a dedicated supply line from the RO system to your refrigerator, providing crystal-clear ice cubes and chilled water.

How We Complete Your Service
- Water Purity Testing & Cabinet Planning: We test incoming tap water TDS using a digital meter and evaluate under-sink cabinet space for the filter manifold and pressurized storage tank.
- Water Supply & Drain Saddle Installation: We install a dedicated cold water brass angle stop adapter and mount a code-compliant drain saddle on the sink tailpiece above the P-trap.
- RO Manifold & Faucet Mounting: We drill or utilize an existing sink knockout hole to mount the designer faucet, securely hanging the 4- or 5-stage filter bracket inside the cabinet.
- System Sanitization, Flush & TDS Verification: The storage tank is sanitized, filled, and flushed twice to prime carbon filters, followed by a final digital TDS meter test confirming ultra-pure output.
