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.
