Prefer to see the numbers before choosing equipment? Water testing and well water testing can come first.

Point-of-use reverse osmosis for drinking, coffee, ice, and cooking — sized to your sink space and water conditions.
Scheduled filter changes and membrane service so your system keeps producing the water quality you expect.
Slow flow, odd taste returning, leaks under the sink, or a tank that never fills — we diagnose and fix a wide range of brands.
Hardness is a separate job from drinking-water RO. Softener install, repair, and salt for Auburn Hills homes.
Sediment, chlorine taste, or other whole-home concerns that an under-sink RO is not meant to handle alone.
Know what is in your water before buying. Well water testing is available for private wells.
Municipal water in Auburn Hills is treated at the plant, but many households still want a dedicated drinking-water step at the kitchen sink. Common reasons people call us about RO and water purification include:
An RO system is not a softener and not a whole-house iron filter. It is a drinking-water solution. Read more about why homeowners choose reverse osmosis, when whole-house filtration differs from under-sink RO, and how often RO systems need service.
We do not guess at a one-size system. Each reverse osmosis install in Auburn Hills is matched to your test results, household use, and cabinet space. During installation we set the faucet, connect the drain and storage tank, flush the system, and walk you through filter change intervals. When an install needs plumbing work beyond a typical under-sink hookup, we coordinate with our partner, Putman & Son’s Plumbing.
Already have an RO that is slowing down or tasting off? We service a wide range of brands — even units we did not originally install. Common work includes:
When the fix approaches the price of a replacement, we spell out both options clearly. Our RO service guide covers typical maintenance timing in more detail.

Reverse osmosis handles drinking water at one faucet. Hardness scale on fixtures and appliances is usually a softener job. If you already have a softener — or need one — we also offer softener salt delivery, including Dura-Cube® options for Auburn Hills homes and businesses. See our Auburn Hills water softener page for install, repair, and salt details.
Drinking-water RO is one piece of a full water-treatment plan. Depending on what testing shows, Auburn Hills homes may also need softening for hardness, iron filtration for staining, whole-house carbon for chlorine taste at every tap, or backflow testing and repair. We will tell you which pieces your home actually needs — and which ones it does not.
“Highly recommend this company if you’re looking for quality products, expert installation, and top-notch customer service!”

A typical under-sink RO pushes water through a membrane and supporting filters so the water at that faucet is better suited for drinking and cooking. It is a point-of-use drinking-water system, not a whole-house softener. Exact results depend on the system, membrane, and your water conditions.
Often yes, if drinking-water taste or cooking water is the concern. A softener addresses hardness minerals that cause scale and spotting. RO is aimed at the water you drink. Many Auburn Hills homes use both, each for a different job.
Pre-filters and carbon filters are commonly replaced on a schedule based on use and water quality; membranes last longer but still wear out. We set a maintenance plan after looking at your water and how much you drink from the system. Call 248-651-5238 to schedule service.
Yes. Municipal supply and well water often need different pre-treatment ahead of an RO. Wells can vary from property to property. Testing and a look at your plumbing space shape the recommendation.
Price depends on the configuration, whether pre-treatment is needed, cabinet space, and whether we are installing new or replacing an older unit. After we see your water and the under-sink layout, we can quote a real installed number instead of a guess.
Yes. Our technicians work on reverse osmosis units from many manufacturers. If the existing system is worth keeping, we will say so; if replacement is smarter, we will explain why.
Yes, where a residential-style or light commercial RO setup fits the use — offices, break rooms, and similar spaces. Larger commercial needs are evaluated case by case. Start with a call or our commercial water treatment page.
Need a new under-sink RO, overdue filter changes, or ready to stop buying bottled water by the case? Describe what you taste at the tap, and we will outline a practical next step.
