FAQs
Common questions
How much does reverse osmosis system installation cost in Scottsdale?
A typical under-sink reverse osmosis installation in Scottsdale runs $650–$1,400 installed, including the system, dedicated faucet, drilling the countertop if needed, and start-up. Premium tankless or whole-home RO systems range $1,800–$4,500. You'll get a flat written quote before any work begins.
How long does a reverse osmosis system installation take?
Most under-sink RO installations in Scottsdale take 1–2 hours. Add 30–45 minutes if we're running a dedicated line to your refrigerator or ice maker, or drilling a granite/quartz countertop for the new faucet.
Where do you install the reverse osmosis system?
Standard installs go in the cabinet under your kitchen sink with a dedicated drinking-water faucet on the counter. We can also tee a line over to your fridge/ice maker, or install a larger whole-home or garage-mounted RO system if you'd prefer.
Do I need a water softener too if I install RO?
Reverse osmosis only treats the water at one faucet. A softener protects the rest of your home — water heater, dishwasher, faucets and skin — from Scottsdale's hard water. Most homeowners install both, and a softener actually extends the life of your RO membrane.
How often do RO filters need to be changed?
Pre-filters and post-filters every 6–12 months. The RO membrane lasts 2–3 years on average. We offer scheduled filter service across Scottsdale so you don't have to remember.
Can you connect the RO system to my refrigerator or ice maker?
Yes — we can run a dedicated 1/4" line from the new RO system to your fridge for filtered drinking water and clear, taste-free ice.
What brands of reverse osmosis systems do you install?
We install and service APEC, iSpring, Pentair, AquaTru, Culligan, RainSoft and Watts Premier RO systems — both tank-style and modern tankless units. Bring your own or we'll recommend the best fit for your home.
Will an RO system improve the taste of Scottsdale tap water?
Significantly. Reverse osmosis removes 95–99% of dissolved solids, chlorine, sediment and the mineral taste that comes with the Valley's hard water — your drinking water and ice will taste noticeably cleaner.
