Equipment choices
- Number of stages: sediment, carbon, membrane, post-filter and an alkaline stage in Living Water's systems.
- Tank or compact design: affects cabinet space and flow.
- Certification: models with more NSF/ANSI 58 claims may cost more; make sure the claims match what you care about.
Living Water's alkaline RO adds a remineralization stage after the membrane, which is part of the equipment cost and of the filter schedule.
Installation factors
| Factor | Why it changes the quote |
|---|---|
| Faucet placement | Existing hole, new hole in the sink, or countertop drilling |
| Drain connection | Ease of tying into the sink drain |
| Ice maker or fridge line | Extra tubing run and fittings |
| Cabinet space | Tight cabinets may need a compact unit |
| Water pressure | Low pressure can call for a booster |
Running costs to ask about
- Replacement schedule for each pre-filter, post-filter and alkaline cartridge.
- Membrane life, which depends on incoming water and use.
- Water sent to the drain during production.
- Service visits, if you want them handled for you.
Florida City's free chlorine is handled by the carbon pre-filter; changing it on time protects the membrane. Read RO maintenance and operating costs.
Also ask whether the quote assumes a storage tank or a tankless design; see tankless vs. tank RO.
Compare with what you spend now
If your household buys bottled water, list how many cases a month you use. That is the fair comparison. Our bottled water vs. RO calculator walks you through it.
Quote checklist
- Exact model number and its certification listing.
- Installation labor and parts, itemized.
- Filter part numbers and intervals.
- Warranty for equipment and labor.
- Who to call for service.
Living Water offers financing through its financing partners; you apply with a credit application, and a co-applicant can apply with you.
Why the cheapest option may cost more later
An RO system with hard-to-find filters, no certification listing, or no local service can cost more over its life than one with a slightly higher starting price. Ask how filters are delivered, who changes them, and what happens if a part fails. Those answers belong in the quote.
Florida City specifics
The city's 2025 report lists free chlorine averaging 1.43 ppm. The carbon pre-filter handles it, and its life depends on how much water your household uses. Jorge sets the change interval from your test and use, not from a generic sticker.
