Equipment choices that move the price
- Stages and membrane capacity: more stages and higher output change the system.
- Tank or tankless: tankless saves cabinet space; see tankless vs. tank RO.
- Alkaline stage: adds minerals back for taste.
- Leak stop: worth asking for in any building.
Installation choices that move the price
- Faucet: using an existing hole vs. drilling quartz or granite.
- Fridge or ice-maker line: routing tubing through cabinets.
- Drain connection: depends on the sink setup.
- Cabinet space: tight or shared cabinets in older units may need compact equipment.
- Building rules: insurance certificates, work-hour limits and notice can affect scheduling.
In older Surfside buildings, the shutoff valve under the sink may be decades old. If it does not close fully, replacing it is a sensible first step and a small line item to expect.
Chloramine and long-term cost
The Town distributes WASD water carrying chloramine, 2.5 ppm for WASD's main system in 2025. RO membranes need protection from chlorine-based disinfectants, and chloramine is harder on ordinary carbon. A pre-filter suited to chloramine and changed on time protects the membrane, which is usually the most valuable part to replace. Ask how long each filter lasts at your water use.
Ownership costs to ask about
- Pre-filter and post-filter change intervals.
- Membrane life.
- Alkaline cartridge replacement.
- Water sent to drain per gallon produced.
- Whether service visits are included.
See RO filter replacement cost and RO maintenance and operating costs.
Questions that keep the quote honest
- What did my tap test show for chloramine and total dissolved solids?
- Which stage handles chloramine, and how often is it changed?
- Is the countertop drilling included, and who is responsible for the stone?
- Is the fridge line included?
- What paperwork does my building need, and who provides it?
Red flags: health promises, claims that Surfside's water is not drinkable, contaminant claims without a model number and certification listing, and same-day pressure. If you buy bottled water now, compare with the bottled water vs. RO calculator.
Compared with bottled water
Surfside households that buy cases or pay for delivery often compare that ongoing spending with RO's filter changes. The bottled water vs. RO calculator walks through the math with your own numbers, including storage space, which is tight in many condo units.
