Common questions about reverse osmosis in Scottsdale
How hard is the water in Scottsdale?
Scottsdale water hardness averages 15-22 GPG, sourced from cap canal water, some well water. This is significantly harder than the national average of 6 GPG, meaning scale buildup, dry skin, and appliance damage are common without treatment.
Do you serve Scottsdale?
Yes — Scottsdale is within our Phoenix metro service area. Our nearest location is in Mesa. We offer free in-home water testing and same-week installation in most cases.
How much does a reverse osmosis system cost in Scottsdale?
Reverse osmosis systems for Scottsdale homes start at $795: Thirst RO Pure from $795, Thirst RO Restore from $895, Thirst RO Thrive from $995. Every system is backed by a 5-Year Part & Labor Warranty. Installation is quoted separately. Pair with a water softener and save $350 with our bundle deal. 0% APR financing for 9 months is available.
Do I still need reverse osmosis if I have a water softener?
Yes, for drinking water. A softener removes hardness so your pipes and appliances last, but it does not remove dissolved solids, chlorine, or other contaminants. Reverse osmosis handles the water you drink and cook with — most Scottsdale homes pair both, and the bundle saves $350.
What does reverse osmosis remove from Scottsdale water?
Scottsdale tap water contains Chlorine, chloramines, TDS, some arsenic. A Thirst RO system removes 90%+ of dissolved solids and contaminants, and the RO+ model adds alkaline remineralization for better-tasting water.
Where does a reverse osmosis system install?
Under the kitchen sink, with its own dedicated faucet at the counter. Installation is quoted separately for every RO system we sell in Scottsdale.
How often do RO filters need to be changed in Scottsdale?
Arizona's high dissolved-solids water works filters harder than the national average. Pre-filters are typically replaced yearly and the membrane every few years — we set a schedule based on your Scottsdale water and household usage.
Do you offer financing on reverse osmosis systems in Scottsdale?
Yes — 0% APR financing for 9 months applies to reverse osmosis systems installed in Scottsdale, and pairing RO with a water softener saves $350.
