About Mr. Water LLC

Hagerstown, Maryland's Local Well Water Treatment Experts Since 2005

Scott R. Handy founded Mr. Water Professional Water Treatment of Maryland in 2005, drawing on nearly two decades of hands-on experience as a service plumber and water treatment technician. What started from the back of a 1992 Ford Ranger pickup truck — and a commitment to doing the job right — has grown into Central Maryland's most trusted name in residential and light commercial water treatment, water softening, and water purification services.

Scott's first major installation involved custom-built well water treatment systems for a new housing development in northern Montgomery County, Maryland. Word spread quickly. Homeowners and businesses across Washington County, Frederick County, and beyond recognized something rare: a water treatment specialist who prioritized honest assessments, quality components, and long-term solutions over quick sales.

As demand grew, so did the scope of services. At a time when few companies were willing to perform the labor-intensive work of re-bedding acid neutralizers, rebuilding iron filters, and servicing water softener control valves, Mr. Water LLC filled the gap — servicing and repairing existing equipment from major national brands including Culligan®, EcoWater®, RainSoft®, and Kinetico®, and systems using Fleck®, Clack®, and Autotrol® control valves.

Services expanded to include full installation and maintenance of reverse osmosis drinking water systems, UV disinfection systems, sediment pre-filters, well pressure tanks, and low water pressure correction — making Mr. Water LLC a true one-stop shop throughout Central and Western Maryland, the Eastern West Virginia Panhandle, Northern Virginia, and South Central Pennsylvania.

A First in the Industry

Patented Well Water Treatment Technology

The patented design integrates closed-pressure aeration with ion-exchange water softening in a single tank. An air injector (micronizer) or air pump introduces air into the pressurized water stream ahead of the resin tank, keeping the water passing through the resin bed highly oxygenated. The cation-exchange resin removes calcium and magnesium hardness, while the oxygen-rich environment simultaneously oxidizes dissolved ferrous iron and hydrogen sulfide.

Because oxidation happens within the resin bed itself, the system achieves additional iron and sulfur removal beyond what a separate aeration system and water softener would achieve independently — addressing hard water, iron, and hydrogen sulfide (rotten-egg odor) in one tank instead of three separate pieces of equipment.

System Configurations

  • Capacity: 48,000-grain (standard), 64,000-grain (heavy-duty), 96,000-grain (light-industrial)
  • Aeration: single or dual micronizers, or a single air pump — selected by iron and hydrogen-sulfide load
Documented Field Result

Across 18+ years of installations, the system has treated every water chemistry it's been applied to. In one case documented in Water Conditioning & Purification magazine, it removed approximately 98% of iron from well water testing at 200 ppm — a level most systems can't approach. The only limiting factor was crawlspace tank size, not the technology; with more resin volume and air-contact time, the system is designed to remove even more.

Photos Before a Truck Ever Rolls

Mr. Water LLC is a one-man operation, so the contact form is built around sending photos and a description first. With 38 years in the field, Scott can usually diagnose the problem that way — he'll only come to the house when the job actually calls for it.
