Backflow Testing, Certification & Repair in Garwood Borough, NJ
Garwood Borough is one of Union County’s smallest and most practically oriented residential communities — a tiny borough of approximately 4,600 residents surrounded by Cranford Township, Westfield, and Clark, with a character defined by its working-class and middle-class residential neighborhoods, its modest commercial district along North Avenue, and the NJ Transit Garwood station on the Raritan Valley Line that connects residents directly to New York City. Despite its small size — barely one square mile — Garwood has maintained an independent municipal identity and a tight-knit community character that distinguishes it from its larger neighbors. The borough’s affordability relative to Westfield and Cranford has made it a practical entry point for families seeking residency in Union County’s central residential corridor.
South Jersey Backflow provides certified annual backflow testing and certification, backflow repair and rebuild service, and backflow preventer enclosures for Garwood Borough property owners.
