FAQs
Why is backflow testing required for commercial properties in Harrison?
The Town/Village of Harrison, like the rest of Westchester County, follows New York State Department of Health regulations that mandate annual backflow prevention testing for any commercial building connected to the public water supply. Backflow assemblies keep contaminants such as chemicals, fertilizers, and process water from reversing direction and entering the municipal system. Regular testing verifies that check valves and relief mechanisms remain in proper working order, protecting employee health, customer safety, and the town’s drinking water quality. Failure to comply can result in code violations, fines, and possible water‐service interruption until a passing test report is filed.
How often must my backflow prevention assembly be tested?
New York State requires most commercial, industrial, and institutional properties to have every backflow prevention device tested once per calendar year by a certified tester. Certain high-hazard sites—such as medical labs, auto shops, and food-processing plants—may be required to test twice yearly if specified in their original permit. After a repair, replacement, or relocation of a device, a retest is required immediately to document that the assembly is functioning correctly before being put back into service.
What does your precision backflow testing process involve?
Our technicians arrive with calibrated differential pressure gauges and all manufacturer-approved test kits. We first review the device’s installation for code compliance, then shut off downstream water to minimize business disruption. Each check valve, relief valve, and air inlet is measured for opening pressure, tightness, and leakage in accordance with USC FCCC&HR test procedures. Results are recorded on Harrison’s official form in triplicate—one copy for you, one for the water authority, and one for our records. If your assembly passes, we tag the device with the inspection date and next due date. If it fails, we provide a detailed deficiency report and a quote for immediate repairs.
Are your technicians certified to perform backflow testing in New York State?
Yes. Every member of our backflow team holds a current New York State Department of Health Class B (Tester) certificate and has completed the mandatory 35-hour practical course and biennial recertification. We also maintain Westchester County plumbing licenses and $2 million in liability insurance. Copies of all credentials are available upon request and are attached to the test reports we submit to the Harrison Engineering Department for your peace of mind.
What should I do to prepare my facility for a backflow test?
Please ensure the device is accessible—clear shelving, stored materials, or landscaping around the vault. Verify that shut-off valves upstream and downstream are functional; seized valves can prevent testing. If your device is indoors, let staff know we will briefly interrupt water service (typically 10–15 minutes). Provide any previous test reports so we can compare historical performance. Finally, give us contact information for the building engineer or maintenance manager in case we need authorization for minor onsite adjustments.
What happens if my device fails the backflow test, and how quickly can you provide repairs?
If the assembly fails, we will explain the exact reason—such as a fouled check seat, worn O-ring, or spring fatigue—and give you a written estimate on the spot. Most common repairs can be completed the same day because we stock rebuild kits for leading brands (Wilkins, Watts, Febco, Apollo). After the repair, we perform a retest at no additional charge and file the passing report with the town. If a full replacement is required, we coordinate permits and installation within 24–48 hours to keep you in compliance and avoid fines or water shutoff.
