US Water Systems Review: An Honest Take From a Direct Competitor
US Water Systems is probably the company most like ours in the entire industry: an online catalog selling professional-grade water treatment at published prices, with real water specialists on the phone. So this review has to clear a higher bar than usual. No cheap shots, no scare framing, just what US Water Systems actually is, what the Matrixx and Flexx lines are under the shroud, what owners report, and where the two honest online routes genuinely differ.

Quick Verdict: Is US Water Systems Legit?
Yes. US Water Systems is a legitimate, long-established online water treatment company, founded in the early 2000s by Mark Timmons, a genuine industry veteran, and based in the Indianapolis area. They publish real prices, employ certified water specialists, and sell everything from replacement filters to commercial reverse osmosis. If you are comparing them against a local dealer quote, either of us will save you thousands.
- What they get right: an enormous catalog (their house Matrixx and Flexx lines plus genuine Fleck valves and Clack parts), transparent published pricing, deep technical content, strong warranties on the Matrixx line, and a one-year money-back guarantee on systems their specialists design.
- What buyers should check first: the Matrixx "smart valve" is their own proprietary platform (its companion app is published by Chandler Systems of Ohio, not Fleck or Clack), the perpetual sale pricing means the list price is theater, and the published return policy carries restocking fees of up to 40% with customer-paid return shipping.
- What owners report: reviews skew positive on product quality and technical knowledge, with the recurring complaints centered on shipping speed and slow refund processing, not on the equipment itself.
- The honest bottom line: this is a comparison between two legitimate online routes, not a dealer-versus-online exposé. The real differences are catalog philosophy (their thousands of SKUs versus our curated lineup), valve platform (proprietary smart valves versus standard Fleck and Clack), and who sizes your system. If you have not tested your water yet, start with a certified lab water test, because neither company can honestly size a system without the numbers.

Who US Water Systems Actually Is
US Water Systems, Inc. is an internet-based water treatment retailer headquartered in Plainfield, Indiana, just outside Indianapolis. It was founded by Mark Timmons, who ran a top-performing Hague dealership in central Indiana before pivoting to e-commerce in the early 2000s, which makes him one of the genuine pioneers of selling water treatment online. Per their own company profile, the model was explicitly inspired by Dell: design and assemble systems, skip the dealer network, and ship factory-direct. It remains a family business with certified water specialists on staff, and they answer real technical questions on the phone.
Stop and notice what that description sounds like. Mid Atlantic Water is also a family company founded by a longtime installer that sells professional-grade equipment online at published prices with expert phone support. US Water Systems is not our opposite; they are our closest analog, and this page treats them accordingly. When a customer asks us "should I buy from US Water Systems?", the honest starting answer is: you could do far worse, and most local dealer quotes are far worse.
The meaningful differences are real, though, and they start with what each company chooses to sell. US Water Systems runs a very wide catalog: their own Matrixx and Flexx system lines, the Bodyguard whole-house filters, residential and commercial reverse osmosis (including whole-house RO), genuine Fleck valves from the residential 5600SXT up to big commercial twins, Clack parts, and thousands of replacement filters. We deliberately run a narrow one: a small number of Fleck and Clack configurations we have installed and supported for decades, sized individually. Wide catalog versus curated catalog is the philosophical fork this whole comparison hangs on.
Matrixx, Flexx, inFusion: The Lineup Decoded
US Water Systems' house brands can be confusing from the outside, so here is the map, built from their own product pages and blog posts (checked live in July 2026):
| Line | What It Is | Key Published Facts |
|---|---|---|
| Matrixx | Their premium line: softeners, backwashing filters, pH neutralizers | Bluetooth "smart valve" programmed via the Legacy View phone app, one internal moving part, 10-year warranty on valve and electronics, lifetime warranty on tank and resin, 10% crosslink resin, WQA Gold Seal certified valve, assembled in Indiana (their Matrixx softener page) |
| Flexx | Their economy line: same jobs, cost-reduced hardware | Ceramic rotary disc valve, no Bluetooth, 7-year valve and electronics warranty; their own blog positions Flexx as the 10-to-15-year product and Matrixx as the 20-to-25-year product (their comparison post) |
| inFusion | Hydrogen peroxide injection iron and sulfur systems (Matrixx or Flexx trim) | Chemical feed pump doses peroxide ahead of a catalytic carbon tank; sold for heavy iron, sulfur, and iron bacteria; Matrixx inFusion from $2,892, Flexx inFusion from $2,255 |
| Bodyguard | Whole-house cartridge-style filtration, often paired with a Matrixx softener as a combo | City-water filter and softener packages with multi-stage filtration claims |
| Genuine Fleck and Clack | They also sell the industry-standard platforms outright | Fleck 5600SXT complete softeners from $799 (0.75 cu ft) to $1,045 (2.0 cu ft), commercial Fleck valves, Clack bypasses and connectors |
That last row matters. Unlike most dealer brands we have reviewed in our brand comparison hub, US Water Systems does not hide the commodity hardware behind a private label. They sell the genuine Fleck 5600SXT right alongside their house brands, at aggressive prices. Credit where due: that is transparency most of this industry refuses to offer.
What Valve Is on a Matrixx? (The Teardown)
The control valve is the only moving, wearing, failing part of a whole-house system, so it is always our first question about any competitor's flagship. US Water Systems describes the Matrixx valve as their own commercial-grade design, assembled and quality-checked in Indiana, with a single internal moving part and a 10-year warranty on the valve and electronics. That warranty is genuinely strong; Fleck's standard residential valve warranty is 5 years, and US Water publishes 10.
Here is the context their marketing does not volunteer. The Matrixx is programmed through the Legacy View smartphone app, and Legacy View is published by Chandler Systems, Incorporated of Ashland, Ohio, the valve manufacturer whose app covers systems "sold under Chandler Systems' three brands (CSI, Clearion and WaterSoft) that use the Legacy View Valve," per the app listing itself. Owner reviews make the same connection; one detailed Trustpilot review of a US Water softener notes plainly that "the app you download is from chandlersystemsinc." If that name sounds familiar, it is the same Ohio valve family behind SpringWell's Bluetooth "Connected Series" head, which we covered in our SpringWell review.
To be precise about what we know and don't: US Water Systems says the Matrixx is their design, assembled in Indiana, and we have no reason to doubt that they spec and assemble it. What the app documentation and owner reports establish is that the smart-valve platform lives in the Chandler Systems ecosystem rather than being a from-scratch US Water invention. That is not a defect. Chandler makes real, professionally distributed valves. It is a risk profile: a newer platform family with a thinner third-party parts-and-service network than Fleck or Clack. If your Matrixx needs a piston or a circuit board in year 12, the part comes from one supply chain. A Fleck or Clack valve can be serviced by essentially any water treatment tech in America with parts from any supply house. That difference costs nothing on day one and can matter a great deal in year 12.
The Flexx line's ceramic rotary disc valve is the same story one tier down: real hardware, shorter track record, single-source parts. Neither is a reason to avoid the brand. Both are reasons to weigh the 10-year warranty against what happens in year 11.

Published Prices, and the Perpetual Sale
All prices below were pulled live from uswatersystems.com in July 2026. Like most online water treatment retailers (SpringWell and Aquasana included), US Water Systems runs a perpetual-sale pricing pattern: the Matrixx softener shows a $2,325 list price crossed out above a roughly $1,232 selling price. The selling price is the real price. There is nothing dishonest about retail anchoring this old, but do not let a "47% off" banner rush your decision; the sale will still be there next month.
| System | What It Is | Price (July 2026, their site) |
|---|---|---|
| Matrixx Smart Metered Softener | Bluetooth smart valve, 10% crosslink resin, 10 GPM / 15 GPM / 20 GPM sizes | $1,232 / $1,549 / $1,751 (list $2,325) |
| Flexx-HD Economy Softener | Ceramic rotary disc valve, no app, 7-year warranty | $924 to $1,381 by size |
| Fleck 5600SXT (genuine) | Complete softener with brine tank, 0.75 to 2.0 cu ft | $799 to $1,045 by size |
| Flexx inFusion | Peroxide injection iron and sulfur system, economy trim | From $2,255 |
| Matrixx inFusion | Peroxide injection iron and sulfur system, premium trim | From $2,892 |
Two footnotes worth knowing before you compare any of those numbers to anyone else's. First, per their shipping policy, free shipping applies to most orders over $199 ($299 in a list of "extended delivery states" that includes Maryland, Virginia, and West Virginia), but freight orders are excluded, and full-size softeners and filter systems typically ship freight. Check your cart total with shipping before comparing. Second, their published prices are genuinely competitive, and on the genuine Fleck 5600SXT they are lower than ours. We will address that head-on below rather than hoping you don't notice.
What US Water Systems Owners Actually Report
We read through their Trustpilot profile (about 1,030 reviews averaging 3.7 stars as of July 2026), their BBB record, and community threads before writing this, and the honest summary is: the equipment mostly gets praised; the logistics mostly get complained about.
On the positive side, the recurring themes are real technical knowledge on the phone, systems that solve the problem, and satisfied long-term owners. The sentiment in community forums matches; in a r/WaterTreatment thread asking whether their softeners are worth it, the top answer was that the price is higher but "their customer service is pretty dang good and they are very knowledgeable... if you have the budget they're worth it." Their BBB profile shows an A+ rating with only two complaints in three years, which is remarkably low for a company shipping this much freight. And to their credit, they publicly respond to negative reviews with substance; we saw one reply that walked an unhappy whole-house RO owner through why 4,000 ppm brackish well water eats membranes in 2 to 3 years. That is a company that knows water.
The critical themes recur too, and they cluster in three places:
- Shipping speed versus published processing times. The most consistent complaint pattern on Trustpilot is orders (especially parts and filters) taking days longer to leave the building than the site's stated processing windows, including from otherwise-satisfied repeat customers.
- Slow refund processing. Multiple reviewers report multi-week waits for refunds after cancellations or returns. Their own published return policy says to allow 14 additional business days after the return is received, so plan around that if you order speculatively.
- Return policy fine print. The published terms allow restocking fees of up to 40% on some items, customer-paid return shipping, and no returns at all on commercial items including whole-house RO and made-to-order systems. The counterweight is real: they publish a one-year money-back guarantee on residential systems their Certified Water Specialists design for your water. If you buy from them, buy through a specialist consultation so that guarantee applies, and keep the paper trail.
We hear the shipping theme on our own phone line too. This spring, a Michigan homeowner called us while shopping for an iron filter and softener because his existing order with US Water Systems had not arrived after more than three weeks. That is one anecdote, not a statistic, and every freight shipper has bad weeks. But it matched the public review pattern closely enough to be worth reporting.
One BBB Complaint Worth Knowing About
US Water Systems markets heavily on American manufacturing, and for the house-brand flagship lines (Matrixx tanks and valves assembled in Indiana) the claim is specific and credible. One of their two recent BBB complaints, though, came from a buyer of a budget item who found country-of-origin labels from overseas inside the box and felt misled. The honest reading: "Made in USA" applies to their flagship house-brand systems, not to every one of the thousands of SKUs in the catalog. If origin matters to you, ask about the specific product before ordering, from them or from anyone.
Flexx vs Fleck: The Name Confusion Is Real
This section exists because real buyers keep getting tangled in it, including ours. This spring a homeowner emailed us mid-research, "more confused than ever": he had googled Fleck, landed on US Water Systems' pages, and came away believing US Water Systems owned Fleck and that their side-mount "Flexx" valve was Fleck's newest model. Callers have asked us versions of the same question for years.
So, plainly:
- Fleck is a valve brand owned by Pentair, the water treatment giant. It has been in basements for over 60 years, and the 5600 series is arguably the most installed residential softener valve in history. Nobody but Pentair makes Fleck valves.
- Flexx (two Xs) is US Water Systems' own house brand for their economy line. It is not made by Fleck, not owned by Fleck, and is a much newer platform. US Water Systems also sells genuine Fleck valves and systems, which is precisely why a shopper can land on their site and see both names a paragraph apart.
We are not accusing anyone of trickery; brands name things what they name things, and US Water sells the genuine article right alongside. But when two competing product lines on the same website differ by one letter, confusion is predictable, and a buyer who thinks they are getting a Fleck-family valve should check the spelling on the product page before checkout. If you want the deep dive on the real platforms, our Clack vs Fleck comparison covers how the two industry standards actually differ.
Peroxide Injection vs Air Injection for Iron and Sulfur
Here is the biggest philosophical difference in the well-water lineups. US Water Systems' flagship iron and sulfur solution, the inFusion, injects hydrogen peroxide ahead of a catalytic carbon bed. Our flagship, the Fleck 2510 AIO with Katalox Light, oxidizes iron with a maintained air pocket, no chemicals at all. Both are legitimate engineering. They sit at different points on a simple trade-off:
| Factor | Peroxide Injection (their inFusion) | Air Injection + Katalox Light (our 2510 AIO) |
|---|---|---|
| Oxidizer | Hydrogen peroxide, dosed by a feed pump | Compressed air pocket, replenished automatically at backwash |
| Consumables | Peroxide refills forever, pump parts over time | None; media bed lasts 7 to 10+ years |
| Moving parts to maintain | Control valve plus injection pump and tubing | Control valve only |
| Iron capability | Very high, including extreme combined loads | Up to 30 ppm iron, 15 ppm manganese, 10 ppm sulfur |
| Iron bacteria | Genuinely effective; oxidizer breaks the biofilm | Not the right tool for confirmed iron bacteria |
| Entry price (July 2026) | $2,255 (Flexx) / $2,892 (Matrixx) | $2,495 (2.5 cu ft, shipped) |
Our honest position after decades of installs: most private wells do not need chemical injection. The overwhelming majority of iron and sulfur problems we see fall well inside what air injection over Katalox Light handles without a single consumable. Where peroxide earns its complexity is confirmed iron bacteria (the slimy, cotton-candy growth in the toilet tank) and extreme combined loads beyond air injection ratings. If your lab test shows that, an inFusion-style system is a legitimate answer and we will say so on the phone. What we push back on is defaulting to a chemical feed system, with its pump maintenance and forever-consumables, for a well that a simpler machine would treat. Simpler is cheaper to own, and there is less to break. Full details in the iron filter complete guide.

US Water Systems vs Mid Atlantic Water, Side by Side
Matched as fairly as we can manage. Their figures come from their live product pages and published policies (July 2026); ours from our live product pages the same week.
| Category | US Water Systems | Mid Atlantic Water |
|---|---|---|
| Business model | Online catalog, Indianapolis area, family company, ships nationwide | Online catalog, Maryland, family company, ships nationwide |
| Catalog philosophy | Thousands of SKUs: house brands, genuine Fleck, RO, commercial, parts | Curated: a small set of Fleck and Clack systems we have installed for decades |
| Flagship softener | Matrixx, $1,232 to $1,751: proprietary Bluetooth smart valve, 10% crosslink resin, 10-yr valve warranty | Fleck 5600SXT 48K, $1,995 shipped: 10% crosslink resin, the most widely serviced valve platform in America |
| Iron / sulfur approach | Peroxide injection (inFusion, $2,255 to $2,892+): feed pump + peroxide consumable, handles extreme loads and iron bacteria | Fleck 2510 AIO 2.5, $2,495: chemical-free air injection, 30 ppm iron / 15 ppm manganese / 10 ppm sulfur, zero consumables |
| Valve serviceability | Matrixx/Flexx: proprietary platforms, single-source parts; genuine Fleck also available | Fleck and Clack only: parts on supply-house shelves nationwide, any tech can work on them |
| Water testing | Test kits sold in catalog | Certified 53-contaminant lab test ($199) with Aidan's personal interpretation included |
| Sizing process | Self-serve from the catalog, or phone consult with a Certified Water Specialist (a dozen+ staff) | One person: text your water test to Aidan, he sizes it personally, 7 days a week |
| Shipping | Free over $199/$299 by state; freight orders excluded, so systems may carry freight cost | Shipping included in system prices, factory-direct freight from Ohio |
| Returns / guarantee | 60-day returns (unopened), up to 40% restocking, customer-paid shipping; 1-year money-back on specialist-designed residential systems | We would rather size it right the first time; that is what the free phone consult is for |
| Commercial / whole-house RO | Yes, a genuine strength | No. We do residential well and city water treatment, and we say so |
And the row we promised not to bury: on the genuine Fleck 5600SXT, their sticker price is lower than ours. Their 1.5 cubic foot Fleck system lists at $1,010 against our 48,000 grain system at $1,995 shipped. Some of that gap is real spec (our published 10% crosslink resin versus their unspecified "premium high-efficiency" resin, and freight included in our price versus excluded from their free-shipping policy). But we will not pretend the rest away: part of what you pay us for is the sizing conversation, the water test interpretation, and the fact that the person who sized your system answers the phone on Sunday when something drips. If none of that has value to you and you already know exactly what to order, US Water Systems is a fair place to buy a Fleck valve, and so are we. Browse our softener lineup or the iron and sulfur filters to compare configurations.
Where US Water Systems Genuinely Wins
Per our own rules, every comparison we publish names the scenarios where the competitor is the right choice. Here they are, plainly:
Commercial, industrial, and whole-house RO
We do not sell commercial systems or whole-house reverse osmosis, period. US Water Systems does, with real engineering behind it. If you need a 2-inch commercial softener, a high-TDS brackish well solved, or point-of-entry RO, they are the stronger call and we will tell you that on the phone.
Confirmed iron bacteria or extreme combined loads
Air injection is not the tool for iron bacteria. Their peroxide inFusion systems are built for exactly that, and for iron-plus-sulfur loads beyond air injection ratings. When a lab test shows it, chemical oxidation is the honest recommendation.
Parts, filters, and one-stop catalog depth
Thousands of replacement filters, housings, O-rings, and fittings in one place. If you maintain your own equipment and want a single supplier for consumables, their catalog is genuinely useful in a way our curated lineup is not trying to be.
Worth knowing either way
Both companies publish real prices and put real experts on the phone. Whichever way you go, you are avoiding the in-home-quote model that marks equivalent hardware up 2 to 3x. That is the comparison that actually costs people money, and it is covered in our brand comparison hub.
Where the Two Honest Routes Diverge
1. Curated versus wide-open catalog
A catalog with thousands of SKUs puts the sizing burden on you. More options is not more helpful when iron, manganese, hardness, pH, and flow rate all interact; it is just more ways to buy a mismatch. We sell a deliberately short list of configurations because those are the ones we have watched perform for 20+ years, and because a short list forces the conversation that actually matters: what is in your water?
2. Proprietary smart valves versus boring standard platforms
The Matrixx's 10-year valve warranty beats Fleck's standard 5-year term on paper, and the app control is genuinely convenient. Our counterweight is the year-12 question: water treatment systems outlive their warranties, and when a valve needs a seal kit or a board a decade from now, "any tech, any supply house" is a feature no app replicates. We build the whole company on standard, serviceable, unexciting hardware on purpose.
3. Chemical feed versus chemical-free, wherever chemistry allows
Their iron lineup leads with peroxide injection; ours leads with air injection and Katalox Light. For the minority of wells that truly need an oxidizer feed, theirs is the right architecture. For everything else, a system with no pump, no peroxide bill, and no injection tubing is cheaper to own every single year you own it.
4. A dozen specialists versus one Aidan
US Water Systems staffs a team of Certified Water Specialists, and by owner accounts they know their water. Our model is smaller and more personal: the same person who has installed these systems for over 30 years reviews your test, sizes your system, and answers the phone afterward, 7 days a week. Neither model is wrong. One is a well-run department; the other is a name you will actually know. Buyers who want the second one tend to end up here.
What This Assessment Is Based On
Our Cards on the Table
Mid Atlantic Water competes directly with US Water Systems, so read our conclusions knowing that. We have not torn down a Matrixx system in our shop. Every US Water Systems claim here comes from their own published product pages, prices, shipping and return policies, and blog posts, checked live in July 2026 and linked above; from the Legacy View app's own store listing; from public owner reports on Trustpilot, BBB, and community forums; and from what shoppers and switchers have told us directly on support calls and emails (anonymized). Where we state an opinion, it is framed as installer opinion, not fact.
Our honest bottom line: US Water Systems is a legitimate company run by people who genuinely know water treatment, and this industry would be better if more competitors operated like them. The differences that matter are catalog philosophy, valve platform serviceability, chemical versus chemical-free treatment defaults, and how personally your system gets sized. Weigh those against your own water and priorities, and you will land in the right place, whichever site the checkout happens on.
Your Next Best Step
Whichever company you are leaning toward, the sequence is the same. Get real numbers, then size the system, then buy. In that order.
Already have a water test (or a US Water config in your cart)?
Call or text Aidan at 800-460-5810, seven days a week. Send the numbers, or send the exact Matrixx, Flexx, or inFusion configuration you are considering, and he will tell you straight whether it is matched to your water, even if the answer is "their system will work, buy it."
Don't know what's in your water yet?
Start with the certified 53-contaminant well water lab test ($199), or the city water version if you are on municipal supply. Aidan reviews every result personally and tells you exactly what your water needs, and what it does not.
Frequently Asked Questions
Is US Water Systems legit?
Yes. US Water Systems is a long-established, family-owned online water treatment retailer based in Plainfield, Indiana, founded in the early 2000s by industry veteran Mark Timmons. They hold an A+ BBB rating with very few complaints, publish real prices, and employ certified water specialists. Owner reviews skew positive on equipment and technical knowledge; the recurring complaints concern shipping speed and refund processing times rather than the products themselves.
Who owns US Water Systems?
US Water Systems, Inc. is a privately held family business founded by Mark Timmons, who remains its chairman. Before starting the company, Timmons ran a top-performing Hague Quality Water dealership in central Indiana, so the company grew out of real dealer and installation experience rather than pure e-commerce. It is not owned by Fleck, Pentair, or any large corporate parent.
Where does US Water Systems ship from, and do they have retail locations?
US Water Systems operates from Plainfield, Indiana, in the Indianapolis area, and ships nationwide from there. They are primarily an online retailer rather than a chain with local showrooms, so searches for "US Water Systems near me" generally lead back to the Indiana headquarters. Free shipping applies to most orders over $199 (or $299 in certain states), but freight shipments, which include most full-size systems, are excluded from the free-shipping offer per their published policy.
What valve does the Matrixx water softener use?
The Matrixx uses US Water Systems' own proprietary Bluetooth smart valve, assembled in Indiana, with a 10-year warranty on the valve and electronics. It is not a Fleck or Clack valve. Its companion app, Legacy View, is published by Chandler Systems, Inc. of Ashland, Ohio, the valve manufacturer whose platform also appears in other brands' smart valves, so the Matrixx lives in that ecosystem rather than the Fleck or Clack parts networks. It is real, professionally made hardware; the trade-off is a thinner third-party parts and service network than the two industry-standard platforms.
Is Flexx the same as Fleck?
No. Fleck (one X) is the 60-year-old valve brand owned by Pentair, one of the two industry-standard platforms. Flexx (two Xs) is US Water Systems' own house brand for their economy line, built on a ceramic rotary disc valve with a 7-year warranty. US Water Systems sells both genuine Fleck systems and their Flexx house brand, which is why shoppers regularly confuse the two names. Check the spelling on the product page before you buy, whichever one you intend to get.
Is the Matrixx water softener worth it?
If you value app control and a 10-year valve warranty, the Matrixx at roughly $1,232 to $1,751 (July 2026 prices) is competitively priced quality hardware with 10% crosslink resin and a lifetime tank and resin warranty. The honest counterpoints: the smart valve is a proprietary platform with single-source parts, and equivalent-capacity systems on the universally serviced Fleck platform are available for similar or less money, from US Water Systems themselves ($799 to $1,045) or from us ($1,995 shipped with personal sizing). Decide how much the app is worth to you in year 12 when the system needs a part.
What is US Water Systems' return policy?
Per their published policy: house-brand residential items can be returned new, unused, and unopened within 60 days, less actual shipping costs, with customer-paid return shipping and possible restocking fees of up to 40% depending on the item. Commercial items, whole-house RO, and custom-built systems are generally not returnable. They also offer a one-year money-back guarantee on residential systems designed for your water by their Certified Water Specialists, which is the stronger protection; if you buy from them, buy through a specialist consultation so it applies. Refunds are processed after the return is received, plus roughly 14 additional business days.
How does US Water Systems compare to Mid Atlantic Water?
They are the two most similar companies in this comparison series: both family-owned online retailers selling professional-grade equipment at published prices with expert phone support. The real differences: US Water Systems runs a huge catalog (house-brand Matrixx and Flexx smart valves, peroxide injection iron systems, commercial and whole-house RO, thousands of parts), while Mid Atlantic Water runs a deliberately narrow lineup of standard Fleck and Clack systems, leads with chemical-free air injection for iron, includes shipping in system prices, and has Aidan personally size every system from a certified lab test, 7 days a week. Commercial needs and iron bacteria favor them; standard residential well and city water problems, sized personally on serviceable platforms, favor us.
Aidan Walsh has been in the water treatment industry for over 30 years and has sized, supported, and troubleshot thousands of whole-house systems on private wells and city water across the United States, including plenty originally bought from US Water Systems and other online catalogs. Mid Atlantic Water is a family-run, online-only water treatment company: every system is sized by phone from real water test numbers and shipped nationwide.
