Removes Dissolved Solids
Gilbert's tap water typically tests at 400 to 700 ppm TDS. A correctly installed NSF/ANSI 58 certified RO system reduces that to under 25 ppm, removing the dissolved minerals and salts that affect water quality and taste.

RO System Installation in Gilbert, AZ
Gilbert’s water supply draws from the Colorado River, Salt River Project canals, and local groundwater wells. The Town of Gilbert meets all EPA drinking water standards, but TDS levels in Gilbert’s water typically range from 400 to 700 parts per million according to the Town’s Annual Water Quality Report, along with chlorine residuals used in the treatment process.
That’s the part most people notice first. The taste. An RO system removes dissolved solids, chlorine, heavy metals, and other contaminants at the point of use, delivering clean water straight from your tap. Every project starts with a free in-home water test so we know exactly what we’re dealing with before recommending anything.

Key Benefits of RO Systems
Eliminates Chlorine
Activated carbon pre-filter stages remove chlorine and chloramine before water reaches the RO membrane, eliminating the chemical taste and odor that many Gilbert homeowners notice straight from the tap.
Adds Another Filtration Barrier
An RO membrane adds another layer of protection against microscopic contaminants, working alongside standard municipal water treatment.
Reduces Heavy Metals
NSF/ANSI 58 certified RO systems remove up to 98% or more of lead, arsenic, chromium, cadmium, and other heavy metals, addressing contaminants that standard carbon filters can't reliably reduce.
Replaces Bottled Water
A Gilbert family spending $40 to $60 per month on bottled water can recoup the cost of a professionally installed RO system within 12 to 18 months, while eliminating plastic waste in the process.
Protects Appliances
Gilbert's hard, high TDS water causes scale buildup inside ice makers, coffee machines, and dishwashers. RO-treated water at the kitchen tap reduces that mineral load on water-fed appliances significantly.
Better Tasting Water
With dissolved solids, chlorine, and heavy metals removed, RO water tastes clean and neutral straight from the tap. Many Gilbert homeowners add a remineralization stage for a naturally balanced mineral taste.
Expert Installation
Every installation includes a pre-installation water test, code-compliant connections, a dedicated drinking water faucet, and a full homeowner walkthrough covering filter replacement schedules.

Everything You Need for Better Water
01
Under-Sink RO Installation

Real Results from Gilbert Homeowners
Hear from customers who had an RO system installed by our team.
“Had Evolution come out to install a water softener and a reverse osmosis system. Ryan was informative, taught me upkeep and what I'd need to maintain both systems. Didn't force my decision and gave me options explaining pros and cons with different brands. Transparent throughout. Ryan has fully gained my trust.”
“I recently had Evolution Plumbing service both my tankless water heater and RO system. Justin was punctual, professional, and took the time to explain the flushing and maintenance processes for both systems. The RO system was thoroughly cleaned and checked, and it's now providing purified water like new.”
“Love these guys! Had them swap out our old softener and install an RO system and new kitchen sink a year ago. Our water tastes WAAAAY better than anything bought in a bottle.”

Which System Is Right for You?
Under-Sink vs Whole-House RO: Which System Is Right for You?
Not sure which type of RO system suits your home? Here's how the two options compare.
Under-Sink RO
Most PopularInstalled beneath your kitchen sink, an under-sink RO system treats water at a single point of use. It delivers purified drinking and cooking water straight from a dedicated tap, with most installations completed in two to three hours.
Advantages
- Lower upfront cost than a whole-house system
- Fast installation with minimal disruption
- Ideal for most Gilbert households on municipal supply
- Pairs naturally with a whole-home water softener for comprehensive coverage
Considerations
- Treats water at one tap only, not throughout the home
- Storage tank requires occasional maintenance and filter changes
- Not suitable where whole-home filtration is a priority
Whole-House RO
Maximum FiltrationInstalled at the main supply line, a whole-house RO system treats every drop of water before it reaches any tap or appliance in the home. Best suited to properties with very high TDS levels or where skin sensitivity and appliance protection across the entire home is a priority.
Advantages
- Treats every tap, shower, and appliance in the home
- Maximum protection for skin, appliances, and plumbing
- Ideal for properties with very high TDS or specific health requirements
Considerations
- Higher upfront cost than an under-sink system
- Requires more complex installation and ongoing maintenance
- For most Gilbert homeowners on municipal supply, an under-sink system paired with a water softener is a more cost-effective solution

Common Questions
RO Systems FAQs
Can I install my own RO system, or do I need a professional?
A basic under-sink kit is a feasible DIY project if you're comfortable with basic plumbing. A licensed installer adds code-compliant air-gap connections, pressure verification, and proper setup that DIY installations often miss. Professional installation also helps protect warranty coverage. For most Gilbert homeowners, it is the more cost-effective choice in the long run.
What are the downsides of a reverse osmosis system?
Two things worth knowing upfront. RO systems produce some wastewater during operation. Traditional systems produce 3 to 4 gallons of wastewater per gallon of purified water, though modern high-efficiency membranes reduce this to closer to 1 to 1. They also remove beneficial minerals alongside contaminants, though a remineralization stage can address that if preferred. Pre-filters and post-filters need replacing every 6 to 12 months and RO membranes typically last 2 to 3 years. Real trade-offs, worth weighing against your household's water quality goals.
Does RO water remove beneficial minerals?
An RO membrane removes calcium and magnesium ions along with contaminants. If mineral intake from drinking water is a concern, we can add a remineralization stage as the final filter, restoring a natural mineral balance and improving taste. According to the World Health Organization, minerals from drinking water typically represent a small fraction of total dietary intake for most people.
Is reverse osmosis water safe to drink?
Yes. RO filtration reduces chlorine, heavy metals, nitrates, fluoride, and many microscopic contaminants, producing clean, safe drinking water. Gilbert's tap water meets all EPA standards, but TDS levels of 400 to 700 ppm and chlorine residuals concern many homeowners. RO water is standard in medical and food service environments and is considered one of the most effective point-of-use treatment methods available.
How long does an RO system last?
A quality under-sink RO system typically lasts 10 to 15 years with correct installation and regular filter maintenance. The membrane itself lasts 2 to 3 years under normal use, with pre-filters and post-filters needing replacement every 6 to 12 months. Keeping up with filter changes is the single most important factor in maintaining system performance and longevity.
How often do RO filters need replacing?
Pre-filters and post-filters typically need replacing every 6 to 12 months depending on your water quality and usage. The RO membrane itself usually lasts 2 to 3 years. Gilbert's relatively high TDS levels mean filters may work slightly harder than in softer water areas, so sticking to the recommended replacement schedule matters more here than it would elsewhere.
What is the difference between an RO system and a water filter in Gilbert?
A standard water filter reduces chlorine and some contaminants but doesn't address dissolved solids or heavy metals. A reverse osmosis system uses a multi-stage process to remove up to 95 to 98% of dissolved solids, heavy metals, and chlorine, delivering significantly better purification at your tap. For Gilbert homeowners dealing with TDS levels of 400 to 700 ppm, the difference is noticeable.
How do I know if I need an RO system in Gilbert?
If you rely on bottled water for drinking and cooking, notice the taste of your tap water, or want to remove contaminants beyond what a standard filter can address, an RO system is worth looking at. Gilbert's tap water TDS of 400 to 700 ppm often sits above the EPA's 500 ppm secondary aesthetic guideline, and most homeowners notice the difference after installation. A free in-home water test will confirm your current water quality and help determine the right system for your home.
