Price drivers
- Stages and alkaline remineralization.
- Tank or tankless: see tankless vs. tank RO.
- Countertop: stone and tile need careful drilling; a spare sink hole avoids it.
- Older shut-off valves and supply lines, which sometimes need replacing first.
- Extra lines to a fridge or ice maker.
Jorge measures and checks all of these before quoting.
Older kitchens
Many Miami Springs homes are decades old. Under-sink plumbing may include original valves or past repairs, and cabinets can be tight. Jorge checks all of it before quoting so the price doesn't change on installation day.
If you'd rather not drill a stone countertop, a spare sink hole or a soap-dispenser hole can often take the faucet.
Running costs
- Replacement intervals for pre-filters, membrane and post-filter.
- Drain water, which shows on your WASD bill.
- Service visits and what's included.
- Whether replacement filters are standard sizes or proprietary.
See RO maintenance and operating costs and filter replacement cost.
Pre-filters protect the membrane, so skipping their changes usually costs more later in a shortened membrane life. A quote that lists the full schedule up front lets you plan for it and compare apples to apples.
How local water affects upkeep
WASD's Hialeah and Preston plants soften and filter the water, and the carbon pre-filter handles chloramine. Sediment stirred up during the yearly hydrant flushing is caught by the sediment pre-filter. Your measured dissolved solids help set a realistic filter schedule.
On a private well, the well usually needs treatment before RO, which changes the plan and total.
Compare with bottled water
Add up a year of bottled water, including trips and storage, and compare with RO ownership costs using bottled water vs. RO.
Households that go through several cases a week usually see the difference fastest.
Where to start on a budget
If drinking water taste is the main complaint, RO alone may do it. If the shower smell bothers you more, whole-home filtration comes first. Jorge tells you which order fits your results.
One system alone is often enough, and he'll say so.
What the quote should show
Model, stages, faucet, labor, filter schedule and written warranty. Living Water offers financing through its financing partners with a credit application; a co-applicant can apply with you. Call, text or WhatsApp (305) 793-5974.
If the test shows you don't need RO, Jorge will tell you.
