Backflow Testing, Certification & Repair in Hillside Township, NJ
Hillside Township is a densely developed urban-suburban community in northeastern Union County — a township of approximately 21,000 residents adjacent to Newark and Elizabeth, with a character shaped by its diverse population, its position at the intersection of major transportation infrastructure (the New Jersey Turnpike, Garden State Parkway, Routes 22 and 78), and its significant commercial and industrial development. Hillside has a long manufacturing heritage — the township was home to Merck & Co.’s original research campus and various pharmaceutical and chemical industrial operations — and its commercial zones along Route 22 and Liberty Avenue create a varied backflow compliance landscape that spans residential neighborhoods, commercial properties, and industrial facilities.
South Jersey Backflow provides certified annual backflow testing and certification, backflow repair and rebuild service, and backflow preventer enclosures throughout Hillside Township for all residential, commercial, and industrial property types.
