Most Gaithersburg homes run on WSSC city water — reliably hard, and in some areas carrying heavier chlorine taste and odor than others. For those homes, a properly sized water softener paired with a carbon pre filter handles the hardness and strips out the chlorine.
Private wells are a different animal: out in Laytonsville, Damascus, Germantown and Clarksburg you'll find every water problem there is — hardness, iron staining, rotten-egg hydrogen sulfide, acidic low-pH water, sediment, and more, often several at once. Every system we install is a custom-built EcoSoft unit, assembled from commercial-grade components and sized to your exact water chemistry — not pulled off a shelf.
For wells fighting iron and hydrogen sulfide, our EcoSoft systems use Scott Handy's patented closed pressure aeration system (U.S. Patents #9,434,626 and #9,499,417): an air injector continuously puts an air pocket into the cation exchange water softener tank to oxidize the iron and sulfur, so a single tank removes hardness, iron, and rotten-egg odor together — with no feed pump adding in chlorine bleach and no separate iron filter tank to maintain. Like any conventional salt-regenerated softener, it recharges with ordinary softener salt, yet needs no more upkeep than a standard unit. One system instead of a basement full of them.
Montgomery County Maryland Water Filtration Repair Services
Gaithersburg has some genuinely interesting water. Along the Goshen School Road, Brink Road, and Woodfield Road areas you can go from very acid water to hard water to irony water in just a quarter mile or so. We've seen neighbors directly across the street from one another — one with very acid water, the other with hard, irony water. Sulfur water (hydrogen sulfide) that smells like rotten eggs isn't nearly as common here as in other parts of Maryland, but it's not unheard of. There are well systems over in Rockville with terribly irony and smelly water, too.
Hard water problems show up in Poolesville on both wells and city water, and depending on location, Dickerson, Darnestown, and Boyds can have very hard water that calls for a water softener. Acidic low-pH water is common as well, which we correct with an acid neutralizer, and iron problems are handled with the right iron filtration for your water chemistry.
Certain geologic conditions increase the likelihood of E. coli and coliform bacteria — especially near sources of fecal contamination like farms or leaking septic systems. There are no known caves in Montgomery County, but small, inaccessible underground voids most likely exist and can be the cause of bacterial contamination in nearby wells. Nitrates from agricultural fertilizers and farm runoff are the main concern for well owners here, and in a densely populated area like Montgomery County, chemicals from urban life — petroleum byproducts, antifreeze — have been and continue to be a source of well contamination.
Low water pressure? We fix that too. In many homes we can boost weak water pressure without the cost of a well booster pump — and when a waterlogged or failed pressure tank is the culprit, we install new well pressure tanks sized correctly for your pump and household demand, so you get steady pressure and longer pump life.
Mr. Water LLC provides water softener, acid neutralizer, iron filter, and well water treatment repair and installation service throughout Montgomery County, Maryland — including Gaithersburg, Rockville, Germantown, Darnestown, Derwood, Damascus, and Potomac.
Reverse Osmosis Drinking Water Systems in Gaithersburg & Montgomery County
For drinking and cooking water, we install high purity Reverse Osmosis systems as a standard part of our Gaithersburg service. WSSC water carries chlorine, disinfection byproducts, and total dissolved solids that swing with the Potomac's seasonal levels — and problem wells can bring nitrates, sediment, and dissolved minerals that a whole-house system isn't built to polish out.
A point-of-use Reverse Osmosis filtration system filters your drinking water down to the molecular level for clean, great-tasting water from a dedicated faucet at the kitchen sink. It's also one of the most effective ways to reduce PFAS — the so-called “forever chemicals,” including PFOA and PFOS — which have become a growing concern in both municipal and private well water. These compounds don't break down in the environment and aren't reliably removed by an ordinary carbon or sediment filter, but a properly maintained reverse osmosis system reduces them along with the widest range of dissolved contaminants of any point-of-use option. Where the layout allows, we prefer to install the RO unit in the basement rather than under the kitchen sink — it frees up your cabinet space, makes filter changes easier, and keeps the system out of the way while feeding the same dedicated drinking-water faucet. In most cases we can also plumb the RO water to your refrigerator's ice maker and cold-water dispenser, so you get the same filtered water for ice and drinks straight from the fridge. We size, install, and service the system and handle the filter changes, so it keeps performing without you thinking about it.
