Upfront cost drivers
- Tank or tankless design and daily volume.
- Stages, including any alkaline remineralization stage.
- Faucet and counter: drilling stone or quartz takes more work.
- Extra lines to a refrigerator or ice maker.
- Cabinet space, drain access and leak protection.
Older kitchens sometimes have cramped cabinets or drain lines that need an extra fitting. Jorge looks at this before quoting, not after.
Seacoast water and RO upkeep
Chloramine wears on carbon faster than free chlorine, and RO membranes depend on that carbon for protection. With Seacoast's 2025 results between 3.6 and 3.8 ppm every month, the pre-filter sees a steady load. On the other side, Seacoast already membrane-treats its water, so dissolved solids at the tap tend to be low, which is generally gentle on a home membrane. Ask how both facts shaped the replacement schedule.
Ask how many gallons per day the model is rated for, and whether that fits your household.
Ongoing costs to ask about
- Pre- and post-filter replacement intervals.
- Membrane life at your water and use.
- Alkaline stage replacement.
- Whether reminders or service visits are included.
- Warranty on the unit and installation.
See RO maintenance and operating costs.
Get the replacement schedule in writing, with what each filter does, so you can plan yearly upkeep.
Comparing quotes fairly
Ask each installer to list the faucet, drain saddle, leak protection and first filter set, and to name the pre-filter type. A quote with a chloramine-rated pre-filter and one without are not the same product. See how to compare water treatment quotes.
Also ask what is covered if a fitting leaks after installation, and for how long.
Bottled water comparison
Many households switch to RO to stop buying bottled water. Run your own numbers in the bottled water vs. RO cost calculator.
Count every bottle and delivery, plus the time spent carrying cases to the house or boat. For a family, the gap often shows quickly; for a single seasonal resident, it may not, and Jorge will say so.
Remember to count ice and coffee.
