Backflow Testing, Certification & Repair in Demarest Borough, NJ
Demarest Borough is one of Bergen County’s most exclusive and bucolic residential communities — a small, wooded borough of approximately 4,900 residents in northeastern Bergen County that has maintained an extraordinary residential quality through low density, exceptional schools, and a genuine commitment to preserving its wooded character. Demarest is one of the wealthiest communities in Bergen County by per-capita income, and its collection of estate-scale residential properties on large, heavily treed lots gives it a rural-suburban character found in few other Bergen County communities this close to New York City. The borough has no significant commercial development — reinforcing its purely residential identity.
South Jersey Backflow provides certified annual backflow testing and certification, backflow repair and rebuild service, and backflow preventer enclosures throughout Demarest Borough for all residential and institutional property types.
