Maryland's LOCAL Water Treatment Experts for the last 22 years!
Clean, Clear, Great-Tasting Water for Maryland, West Virginia, Northern Virginia & Southern Pennsylvania — Guaranteed.
If your water isn’t clean, clear, and great-tasting, you’ve come to the right place.
Mr. Water LLC was founded on a straightforward principle: homeowners and businesses across the region deserve a certified water treatment expert they can genuinely trust — not a salesperson chasing a commission. Owner Scott R. Handy brings over 38 years of hands-on experience diagnosing and solving the full spectrum of residential and light commercial water quality problems. He’s seen it all. More importantly, he’s fixed it all.
Whole-House Water Treatment Solutions — Custom Built for Your Water Chemistry
We provide complete point-of-entry water treatment system installations, repairs, and preventive maintenance across Maryland, the West Virginia Panhandle, Northern Virginia, and Southern Pennsylvania — including:
Water Softeners · Acid Neutralizers · Iron & Manganese Filters · Hydrogen Sulfide & Sulfur Removal · Reverse Osmosis Systems · UV Disinfection · Sediment Pre-Filtration · Well Pressure Tank Service · Low Water Pressure Correction
Does This Sound Like Your Water?
“It smells like rotten eggs straight from the tap.” “Our fixtures and laundry have orange iron stains on everything.” “Three different companies have looked at it and nothing has changed.” “Our well water pressure has always been terrible and nobody can figure out why.”
These are the most common well water problems we hear every week — and solve every week. Whether you’re on a private well dealing with high iron content, low pH acidic water, hydrogen sulfide odors, hardness and calcium scale buildup, or chronic low water pressure, we have a proven, cost-effective solution built specifically around your water test results and household flow rate demands.
Patented Water Treatment Technology — A Long-Term Cost Advantage for Our Customers
What truly sets Mr. Water LLC apart is innovation backed by intellectual property. Owner Scott R. Handy has been awarded two United States Patents for his technological advancements in well water treatment system design:
USPTO #9,499,417 | USPTO #9,434,626
This patented technology — proven across 18+ years of real-world installations treating extreme water chemistries — delivers a significant long-term cost savings over traditional multi-tank water conditioning equipment setups. Instead of a basement full of separate systems for iron filtration, sulfur removal, and water softening, our proprietary single-system design handles hard water, high iron, and hydrogen sulfide contamination in one compact, efficient unit.
Built from commercial-grade generic components and fully customized to your water chemistry, this is whole-house water treatment engineering that no national franchise or big-box brand can match.

Done With Water Treatment Companies That Don’t Deliver?
We service and repair most major national brands — including Culligan®, EcoWater®, RainSoft®, Kinetico®, and systems using Fleck®, Clack®, and Autotrol® control valves — so switching to us is easy. No starting over, no unnecessary equipment upsells, no empty promises. Just honest, expert work from a local water quality specialist who stands behind every single job.

Custom Built Water Filtration Systems
Well Water Treatment Systems Built For Your Water — Not Someone Else’s
Most well water treatment companies sell you an off-the-shelf system and hope it works. We do it differently. We start with a full water quality analysis, factor in your household usage, and engineer a custom point-of-entry treatment system using commercial-grade components built to last.
The result is a whole house well water purification system that actually solves your specific water problem — whether that’s hard water and calcium scale buildup, iron and manganese staining, hydrogen sulfide odors, low pH acidic water, high sediment and turbidity, bacteria, nitrates, PFAS, or other chemical contamination.
We install and service a complete range of water filtration equipment for private well owners — water softeners, iron filters, acid neutralizers, aeration systems for hydrogen sulfide removal, UV disinfection, reverse osmosis, sediment filters, and well system pressure tanks — all properly sized and configured for your home’s water chemistry and flow rate demands.
If your well water has a problem, we’ve fixed it before — and we’ll build you a system that keeps it fixed for years to come.

Water Softeners for City Water
City Water Problems? We Have the Right Fix for Home and Small Business Owners
Municipal water quality varies widely depending on your location, the season, and even the current river levels supplying your local water district. Hard water, chlorine taste and odor, disinfection byproducts, and fluctuating total dissolved solids (TDS) are everyday realities for Maryland city water customers — and they all require the right equipment to fix for good.
A word on salt-free softeners: Template-assisted crystallization (TAC) and other so-called “salt-free” or “saltless” conditioning systems do not remove hardness minerals. Calcium and magnesium remain in your water, and limescale buildup continues. They are not a substitute for a true cation exchange water softener — and they rarely justify their high price tag.
For genuine hardness removal, a properly sized cation exchange water softener is the only proven solution. We custom build each system around your water’s specific hardness level, measured in grains per gallon (GPG), along with your flow rate and daily usage.
Water suppliers like WSSC draw from surface water sources such as the Potomac River, meaning hardness levels, chlorine dosing, and TDS concentrations shift throughout the year — sometimes by 10-20 GPG or more. Water temperature swings from the mid-40s in winter to nearly 80°F in summer also affect how efficiently carbon filters reduce chlorine and chloramines, and how well softeners perform ion exchange.
We account for all of it — so your system works as well in February as it does in August.
Contact us today to find the right city water treatment solution for your home or business.
Maryland's Trusted Local Water Quality Specialists — Experience You Can Count On.
Skip the Free Sales Pitch — Get a Real Water System Assessment
“Free” water tests from salespeople aren’t really about your water — they’re about selling you a basement full of filtration equipment. Basic test kits in the hands of untrained salespeople can’t accurately measure water hardness, iron content, pH levels, or the full range of contaminants affecting your home’s water quality.
Our water treatment professionals conduct a thorough in-home water quality analysis for just $110 — covering hardness (GPG), pH, iron and manganese, chlorine and chloramine levels, hydrogen sulfide, TDS (total dissolved solids), turbidity, and more. If you decide to get a new system from us during this visit, we will typically waive the service fee. You get a complete, unbiased picture of your water chemistry with honest, straightforward recommendations.
We also offer a full diagnostic evaluation of your existing water conditioning equipment — including pressure tank condition, well pump performance, system flow rate, and overall point-of-entry treatment system functionality. If something isn’t working the way it should, we’ll tell you exactly what it is and what it will take to fix it.
No commission-driven sales tactics. No unnecessary equipment upgrades. Just accurate water testing and expert advice from a company that puts customers first.
Mr. Water Professional Water Treatment of Maryland has built its reputation on honest assessments and lasting solutions — whether that’s a filter media replacement, a pressure tank upgrade, or a fully custom built whole house water treatment system.
Professional Water Treatment Equipment Service & Repair — Most Major Brands Serviced Since 2005
Routine maintenance is the key to keeping your water softener, filtration system, and conditioning equipment performing at peak efficiency for years to come. Mr. Water LLC provides comprehensive preventive maintenance and repair services for most major national water treatment brands — including Culligan®, EcoWater®, RainSoft®, Kinetico®, and systems equipped with Fleck®, Clack®, or Autotrol® control valves.
Our service visits cover everything your system needs to operate reliably — control valve inspection and rebuilding, ion exchange resin bed evaluation and replacement, brine tank cleaning, sediment pre-filter cartridge replacement, UV lamp replacement, reverse osmosis membrane changes, carbon filter media replacement, bypass valve testing, and regeneration cycle calibration.
With over 38 years servicing water conditioning equipment throughout Maryland and surrounding areas, we know the systems installed by local dealers, licensed plumbers, and well drillers inside and out. Whether your water softener has lost efficiency, your iron filter isn’t backwashing correctly, your RO system has dropped in output pressure, or your UV disinfection system is overdue for an annual lamp change — we diagnose it accurately and fix it right the first time.
Don’t wait for a system failure to schedule service. Proactive maintenance extends equipment life, protects your plumbing from hardness scale and iron fouling, and ensures your water quality stays consistent year-round.
