Certified $75 Backflow Testing for Mamaroneck, NY

From the harbor and marinas to the shops along Boston Post Road, Mamaroneck mixes waterfront homes, busy commercial strips, and quiet residential streets — and every property with a backflow preventer needs it tested once a year by law. Whether your water comes through Westchester Joint Water Works or Veolia, Guardian Backflow Testing LLC handles the whole job for a $75 flat rate: the certified test, the paperwork, and the filing with your supplier. With 35+ years in the trade and ABPA membership, we're the dedicated backflow specialists Mamaroneck property owners call first.

Marinas and harbor facilities use washdown connections that put the water supply at real risk, while the restaurants along Boston Post Road depend on backflow devices for soda systems, espresso machines, and dishwashers. Add residential irrigation across the village and town, and Mamaroneck has more backflow preventers per block than most Westchester communities. State law says each one must be tested every year by a certified tester. Guardian Backflow Testing LLC — a NYS-certified, licensed and insured specialist with 35+ years in the field and ABPA membership — covers homes and businesses alike for a $75 flat rate, filing every report for you.

We arrive on time and run a complete test of your assembly — RPZ, DCVA, or PVB — the same certified procedure whether you're a homeowner or a business. The NYS certification paperwork is completed on the spot, and we file your report directly with whichever supplier serves you, Westchester Joint Water Works or Veolia. An emailed copy lands in your inbox for your records. One $75 flat fee covers it all, with no hidden charges.

Restaurants, marinas, and multi-tenant buildings in Mamaroneck typically rely on RPZ assemblies, which face the strictest testing standards — and the harshest consequences if they fail. We test commercial devices on a schedule that works around your business hours, and we can coordinate multi-device properties in a single visit. Facility managers get one clean compliance packet covering every assembly.

Most of the Village and Town of Mamaroneck is served by Westchester Joint Water Works, with some neighborhoods on Veolia Water New York. Both enforce New York State Sanitary Code 5-1.31, which requires every backflow preventer to be tested annually by a certified tester with the report filed to the supplier. Tell us your address and we'll file with the right supplier — it's included in the $75 flat rate.
