Homeowner guide
Planning your reverse osmosis systems service in Fountain Hills
Signs to watch
Poor taste, chlorine odor, cloudy ice, high total dissolved solids, slow faucet flow, or a tank that no longer refills can indicate an RO service or replacement need. We test feed water and product water so recommendations are based on measured performance rather than taste alone.
Before the appointment
Clear the cabinet beneath the sink and decide whether purified water should also feed the refrigerator or ice maker. We check available space, drain access, water pressure, faucet mounting, and existing soft-water treatment before selecting a tank, membrane capacity, and filter configuration.
After the work
The finished system is flushed, sanitized, leak-tested, and checked with a TDS meter. We label the filter-change date and explain shutoff locations. Annual pre- and post-filter service, plus membrane replacement based on testing, protects flow and water quality without replacing parts early.
Homes across Fountain Hills vary in age, piping material, pressure, fixture layout, and prior repairs. We diagnose those conditions on site, explain practical options, and provide a flat written quote before work starts. The goal is a durable repair or installation—not a one-size-fits-all recommendation.

FAQs
Reverse Osmosis Systems questions from Fountain Hills homeowners
Will an RO system improve the taste of our water?
Dramatically. Fountain Hills water is treated but high in dissolved minerals and chlorine. RO drops total dissolved solids from 400–700 ppm down under 30 ppm — coffee, tea and ice taste noticeably cleaner. Most clients tell us they stop buying bottled water within a month.
Do I need a softener before the RO?
Not required, but a softener in front of RO doubles or triples membrane life because hardness ions are the main thing fouling the membrane. If you already have soft water, expect a 5+ year membrane.
Can you run a line to the fridge?
Yes — a 1/4" line from the RO tank to the fridge ice maker and water dispenser is standard. We use food-grade tubing and a shut-off at both ends so future fridge swaps are clean.
How often do filters need changing?
Pre and post filters every 12 months, membrane every 3–5 years depending on inlet hardness. We send a reminder when you're due and stock filters that fit standard housings, not proprietary cartridges.
