$75 Backflow Testing in Yonkers, NY — Homes & Businesses

Yonkers is Westchester's biggest city — Getty Square's commercial blocks, the revitalized waterfront, and block after block of multifamily homes — and across all of it, New York State requires annual backflow testing by a certified tester. Landlords, homeowners, and businesses alike must file proof every year. Guardian Backflow Testing LLC keeps Yonkers compliant at a $75 flat rate per test: the full certified test, NYS paperwork, and filing with your water supplier, from a licensed, insured tester with 35+ years in the field and ABPA membership.

As Westchester's largest city, Yonkers has the county's oldest infrastructure — and the most multifamily housing. Aging service lines see more pressure events, which is exactly when backflow happens, and block after block of rental buildings means hundreds of devices that all need annual testing. Add Getty Square's commercial blocks and light-industrial properties, and the testing volume is enormous.
