Reverse Osmosis System Installation
Bay Area's #1 Choice

The labor for a standard under-sink RO system typically ranges from $200 to $400. For a point-of-entry (whole-house) system, installation can range from $800 to $2,000 depending on the plumbing complexity. We provide a firm, upfront quote after assessing your cabinet space and water line access.

A point-of-use under-sink system usually takes 2 to 3 hours. This includes mounting the filtration unit, installing the dedicated faucet, connecting the storage tank, and tapping into the drain line. Whole-house systems are more intensive and generally require a full day (6 to 8 hours).

RO systems use a semi-permeable membrane to remove up to 99% of contaminants, including lead, arsenic, fluoride, nitrates, and "forever chemicals" (PFAS). It also filters out microplastics, chlorine, and dissolved solids (TDS) that affect the taste and safety of your drinking water.

Low flow is usually caused by low pressure in the storage tank or a clogged pre-filter. The tank should typically have a pressure of 7-8 PSI when empty. If the pressure is correct but flow is still low, the RO membrane may be fouled by sediment or minerals and likely needs replacement.

Sediment and carbon pre-filters should be replaced every 6 to 12 months to protect the system. The core RO membrane is more durable and typically lasts 2 to 4 years. We recommend an annual service visit to sanitize the system and replace the polishing filter for optimal taste.

Standard RO systems produce "brine" (wastewater) as they flush away contaminants. Older models could waste 4 gallons for every 1 gallon of pure water, but 2026 high-efficiency systems have reduced this ratio significantly, often achieving 1:1. We install high-recovery valves to minimize waste.

Yes, most systems require a dedicated, lead-free designer faucet to deliver purified water without it picking up contaminants from your main plumbing. However, we can also integrate the RO system with your refrigerator’s water dispenser and ice maker for high-purity ice.

Yes, the process is so effective it removes minerals like calcium and magnesium along with the bad contaminants. If you prefer the taste and health benefits of mineral water, we can install a remineralization stage that adds a balanced amount of calcite back into the water before it reaches your tap.

Yes. In fact, RO systems and water softeners work perfectly together. The softener removes "hardness" (calcium) that can clog the RO membrane, while the RO system removes the sodium used by the softener. This combination provides the longest possible lifespan for your filtration equipment.

Yes. Since RO systems are connected to pressurized lines, a loose fitting or cracked housing can cause significant cabinet damage. We offer 24/7 emergency support to shut down the system, clear any blockages, and repair leaks to protect your kitchen infrastructure.
