The main cost drivers
- Stages: sediment, carbon, membrane, post-filter, and an alkaline remineralizing stage on Living Water's system.
- Tank or tankless: see tankless vs. tank RO.
- Faucet: a new hole in the countertop, or an existing sprayer hole.
- Cabinet and drain: space for the unit and a drain connection.
- Extra lines: to a refrigerator or ice maker.
- Certifications: models with more NSF/ANSI 58 claims may cost more.
Lauderhill factors
A lot of Lauderhill households live in condos and garden apartments. That keeps an RO install simple in one way, because it sits under one sink, but association rules on plumbing work and access can affect scheduling. In a house, the main variables are the countertop and whether you want a line run to the fridge. The City's water is lime softened before it reaches you, which helps membranes, but the disinfectant level (2.6 ppm average in the 2025 report) affects how the carbon prefilter is chosen and how often it is changed.
What you pay over time
- Prefilters on a schedule set by use and water quality.
- The RO membrane, on a longer interval.
- The alkaline cartridge, on its own schedule.
- Some water sent to drain while the system makes purified water.
Ask for the schedule and the parts list in writing. See RO filter replacement cost.
Where the system goes matters
Most kitchens take an RO unit in the sink cabinet. If the cabinet is crowded with a disposal, a hot water dispenser or shelving, a compact tankless model or a different layout may be needed, and that changes the quote. Some owners prefer the unit in an adjacent cabinet or a utility area with a longer line to the faucet. Jorge looks at the space during the free test so the quote reflects your kitchen, not a generic install.
Questions for any quote
- What is the exact model, and what does its NSF/ANSI 58 listing cover?
- Is installation included, and what if the cabinet needs changes?
- Who replaces the filters, and how do I order them?
- What does the warranty cover, and for how long?
Compared with bottled water
Households that buy bottled water often compare the two. The useful comparison is ongoing: what you buy every month versus filter changes on a schedule. Run your own numbers with bottled water vs. RO.
