What moves the price
- Tank or tankless: space, flow and storage. See tankless vs. tank RO.
- Stages: sediment, carbon, membrane, alkaline, polishing.
- Chloramine-rated carbon: needed on Seacoast water at about 3.7 ppm.
- Faucet and counter: stone tops may need professional drilling.
- Fridge line: distance and routing.
How Seacoast water affects upkeep
Because Seacoast's plant already uses nanofiltration and low-pressure RO, the dissolved load reaching your under-sink membrane is lower than on many South Florida supplies, which can be kind to the membrane. The carbon stages, though, face a steady chloramine level of 3.6 to 3.8 ppm every day, so their replacement schedule matters. Jorge measures TDS and chloramine so the schedule fits your water.
Installation details matter as well. A cabinet shared with a disposal, a hot water dispenser or a pull-out bin may favor a compact tankless unit. A fridge on the far wall means more tubing and labor. Jorge looks at the cabinet, counter material and fridge location during the free visit so the quote reflects the real job.
Ongoing costs to ask about
- Which filters are replaced, and how often.
- Membrane life.
- Whether you can change filters yourself.
- Water sent to the drain.
- Warranty coverage.
See RO maintenance and operating costs and RO filter replacement cost.
Pre-filters may need changing sooner after nearby main repairs, when extra sediment moves through the lines; a sediment stage protects the rest of the system.
RO vs. bottled water
Many households compare RO with what they spend on bottled water. Use the bottled water vs. RO calculator with your own numbers.
Remember to count delivered water's time and storage, not only the bill, when you compare.
Comparing quotes
Ask every installer for the model, stages, filter schedule, installation work and warranty. A quote that cannot tell you which stage handles chloramine is missing the key detail for Seacoast water. Ask too whether the alkaline stage is included or optional.
Ask also who services the system, how quickly, and whether filters are delivered. Those details shape what owning it is really like.
