The system itself
| Choice | Effect on cost |
|---|---|
| Number of stages | More filters, more parts to buy and replace |
| Alkaline post-filter | Adds a stage and a replacement item |
| Tank or tankless | Different hardware, footprint and sometimes power needs |
| Faucet | Style and finish vary |
See tankless vs. tank RO.
Two systems that both say five stages or alkaline can differ a lot in membrane quality, filter capacity and parts availability, so compare model numbers rather than labels.
Your kitchen
- Cabinet space, especially with a disposal.
- Whether a faucet hole exists or the counter must be drilled.
- Drain connection for the RO's reject water.
- A line to the refrigerator or ice maker.
- Condo association rules on contractors.
In Pembroke Pines, many kitchens in newer communities have deep sink cabinets with room for a tank, while some condos and older homes have tighter spaces that favor a compact design. Jorge looks at the cabinet during the free test so the quote fits the space.
Upkeep with Pembroke Pines water
City water here is softened and filtered at the plant, which is easier on an RO membrane than raw well water. The chloramine residual, a 2.8 parts per million annual average in the city's 2025 report, is handled by the carbon prefilters, so ask:
- How often are the carbon prefilters replaced?
- How long does the membrane typically last?
- What do replacement parts cost, and is service included?
- How much water goes to drain per gallon produced?
See RO filter replacement cost.
A membrane fed with softened, prefiltered city water generally has an easier life than one fed with raw well water, but skipping prefilter changes shortens it quickly.
Questions to put to any RO quote
- Which exact model, and what is it certified to reduce under NSF/ANSI 58?
- Are the faucet, drain saddle, fittings and any fridge kit included?
- What is the replacement interval for each stage?
- Is installation labor covered by the warranty, and for how long?
- Who comes out if there is a leak or a drop in flow?
Clear answers make two quotes easy to compare. See how to compare water treatment quotes.
RO vs. bottled water
If you buy bottled water weekly, compare that spending with RO upkeep using the bottled water vs. RO calculator. It is a useful exercise before any quote.
