Two generations in the water treatment industry
Whole-house reverse osmosis & water treatment for Phoenix homes and businesses
We specialize in reverse osmosis systems for businesses and homes — plus softeners, carbon and filtration, ice machines and water vending equipment. Phoenix water is some of the hardest in the country, so we size every system to your water and keep it running with scheduled service.
Whole-house reverse osmosis
Most homes only get RO at the kitchen sink. A whole-house RO system treats every tap, shower and appliance — the same purified water you would buy in a bottle, throughout the house. Phoenix water carries a heavy load of dissolved minerals, and whole-house RO takes them out instead of just softening them.
- No spots on glass, fixtures or cars; no crust on shower heads
- Pure water for drinking, cooking, ice and coffee at every tap
- Protects water heaters, dishwashers, washers and evaporative coolers from mineral build-up
- Complete package: pre-filtration or softener, commercial-grade RO, storage tank, repressurization pump, and UV or remineralization where it fits
- Sized to your household and water use, with scheduled filter and membrane service
It needs a garage or utility space for the storage tank and a drain — send us a photo of the space and we will tell you what fits.
Why come to us for whole-house RO
We have been building and servicing commercial RO systems for decades — whole-house RO is the same engineering on a home scale. It is a treatment system, not just plumbing: the pre-filtration, membranes, flow rates, storage and repressurization all have to be designed to work together. Plenty of people can set equipment; we design it, build it — sometimes our own systems — and keep it running.
We are also the people many homeowners call when someone else's system stops working. That usually makes us the better value, too: the right system the first time, from people who fix these for a living.
Installed systems
Real equipment, set up and running — water stores, bottle-filling stations, softeners and reverse osmosis.
Clean, great-tasting water at every tap — for your home, your office and your business.

Two ways we help
For your business
Coffee shops, tea houses, restaurants, offices, water stores. Scale kills espresso boilers, ice machines and steamers, and bad water changes how your drinks taste. We set up filtration and RO, then service it on a schedule so you never think about it.
Talk about a service agreement →For your home
Spotty dishes, crusty fixtures, a water heater that died early, drinking water that tastes like the pool. We test first, then recommend the right softener, carbon or RO — sized for your household, not whatever's on the shelf.

Water softeners, whole-house carbon and reverse osmosis drinking water on commercial-grade Fleck and Clack valves — parts you can still buy in 15 years. Sized for your household, set up to last in Phoenix water.
For the office
No more hauling 5-gallon bottles. We rent, deliver and service office water on one monthly plan — filters and sanitizing included.
Bottleless water coolers
Hot and cold filtered water plumbed into your line. No bottles to order, store or lift.
Self-filling bottle coolers
Keeps the familiar bottle look, but the bottle refills itself from filtered line water — nothing to swap.
Ice & water dispensers
Filtered water and ice from one unit — break rooms, clinics, gyms and shops.
Commercial reverse osmosis — one of the leading specialists in the Valley
We build, service and repair commercial RO every day, and our service vehicles carry the commercial RO parts other companies usually have to order in — membranes, pumps, controllers, pressure switches, flow meters and fittings — so most repairs get fixed on the first visit. We service many of the water and ice systems throughout the Valley. We also design custom applications and control panels — pumps, tank levels, alarms and automatic shut-offs wired to fit the job, like the RO and control panel we set up for a propagation house misting system.

Why cheap systems fail in Phoenix
Undersized softeners regenerate constantly
A box-store unit sized for "average" water runs out fast on 15+ grain Phoenix water, burns salt, and wears out its valve. We size by grains × people × usage, with room to spare.
Phoenix uses chloramine, not just chlorine
Standard carbon filters barely touch it. It's why "filtered" water can still taste off — and why chloramine chews up cheap softener resin. We use catalytic carbon and chlorine-resistant resin where the water calls for it.
"Salt-free softeners" don't remove hardness
They can change how scale forms; the minerals are still in the water. Sometimes that's the right tool — usually it isn't. We'll tell you straight which one you need.
RO without pre-treatment dies early
High-TDS Phoenix water scales membranes fast if nothing protects them. A properly pre-filtered RO lasts years; an unprotected one can plug in months.
How we work
Test
We check hardness, TDS and chlorine/chloramine at your tap, free.
Recommend
One system, sized to the numbers, with the why written down. No upsell menu.
Supply
The system we recommend, sized to your numbers and built on commercial-grade valves.
Keep it running
Scheduled filter, media and membrane changes. We remind you; you don't have to remember.
What you're paying for
- Commercial-grade Fleck and Clack control valves — parts you can still buy in 15 years, from anyone.
- Media and filters chosen for Phoenix water, not generic cartridges.
- Systems sized with headroom, so they don't work at their limit every day.
- Someone who answers the phone and knows your system when you call.
Service agreements
The cheapest system is the one that keeps working. We put your filters, membranes and softener on a schedule — businesses usually monthly or quarterly, homes once or twice a year — so nothing clogs, scales or fails between visits. One predictable price, no surprise calls.
Common questions
What's the fastest way to reach you?
Send the form or email [email protected]. We're out on jobs most of the day, so messages get answered faster than calls.
Do you work on systems you didn't sell?
Yes — Fleck, Clack and most standard valves. Repairs, rebeds, membrane swaps.
How long should a good softener last?
A well-sized unit on a quality valve, serviced now and then, commonly runs 15+ years. Resin usually needs replacing sooner in chloramine water — we'll check it.
What's a rebed?
Replacing the resin (and sometimes carbon) inside the tank. It brings a tired softener back for a fraction of a new system.
Can you just ship me a system?
Yes — outside Phoenix we ship systems from watersolutionsonline.com.
