Clean, great-tasting drinking water directly from your tap. Eco-Flow installs under-sink reverse osmosis systems throughout Santa Cruz — proper fitting, dedicated faucet, and connection to your ice maker if needed.
Santa Cruz tap water is safe to drink — but it carries enough dissolved minerals, chloramine, and other compounds that many residents prefer filtered drinking water. A properly installed under-sink RO system delivers consistently clean, great-tasting water at the tap without the ongoing cost and plastic waste of bottled water.
RO removes a broader range of contaminants than any other point-of-use filter type. Here's what a standard 4–5 stage system addresses.
Removal rates vary by system and contaminant. A quality 4–5 stage system typically removes 95–99% of total dissolved solids. We can advise on which system is appropriate for your water quality concerns when you call.
Most under-sink RO installations are completed in 2–3 hours. Here's what's involved and what we handle.
Under-sink placement. The RO system itself — tank, membrane housing, and filter stages — mounts inside the cabinet under the sink. We configure the layout to fit your cabinet and leave adequate space for filter access during future replacements.
Supply line connection. We tap into the cold water supply line under the sink using a saddle valve or angle stop, routing a 1/4-inch supply line to the RO system's pre-filter stage.
Dedicated faucet. RO systems deliver water through a separate dedicated faucet mounted to the sink deck or countertop — not your existing faucet. If your sink has an unused pre-drilled hole, we use it. If not, we drill a new hole in the appropriate location.
Drain connection. The system connects to the drain pipe under the sink for the reject water output. We connect at the drain tailpiece or P-trap depending on your configuration.
Ice maker line. If your refrigerator has an ice maker or water dispenser, we can run a dedicated RO supply line to it — so your ice and refrigerator water are also filtered.
Flush and test. We flush the system per manufacturer spec, run through multiple fill cycles, and confirm the system is producing water and holding pressure before we leave.
Not all water filters are equivalent. Here's how RO compares to the most common alternatives.
| Reverse Osmosis (Under-Sink) | Carbon Block Filter | Pitcher Filter (Brita etc.) | |
|---|---|---|---|
| Removes chloramine | Yes | Partial | Minimal |
| Removes heavy metals (lead, arsenic) | Yes (95%+) | Partial | Minimal |
| Removes nitrates | Yes | No | No |
| Removes dissolved solids (TDS) | 95–99% | No | No |
| Requires plumbing installation | Yes — we handle it | Yes (under-sink) or No (inline) | No |
| Dedicated faucet | Yes | Varies | No |
| Annual filter cost (approx.) | $50–$100 | $30–$80 | $40–$80 |
