About Water Gem | Harrisburg's Master Water Supply & Reconditioning Experts Three Generations of Exceptional Customer Service & Technical Trade Support In the water treatment industry, system reliability depends entirely on the mechanical integrity of its individual moving parts. When a whole-home water softener or commercial filtration system fails, the culprit is rarely the media tank itself—it is almost always a worn, malfunctioning, or calcified master control valve. Sourcing high-quality parts, securing technical backup, and finding master-level component rebuilding services requires an established wholesale partner with generations of specialized trade experience. Located in Harrisburg, Pennsylvania, Water Gem stands out as a premier industry leader in the supply, technical maintenance, and specialized reconditioning of high-performance water treatment machinery. As a family-owned and operated institution with 40 years of field-tested experience, our team has spent three generations bridging the gap between national manufacturer lines and local regional dealers. We combine uncompromised technical expertise with the personal accountability of a local partner.
