Questions about backflow testing
How often does a backflow preventer need testing?
Annually in most North Carolina jurisdictions, and after any repair or relocation of the device.
What happens if my device fails?
Most failures are worn rubber components and are repairable on site with a kit. Only badly corroded or damaged bodies need replacing.
Do you file the report?
Yes. We submit the completed test report to the relevant North Carolina authority as part of the service.
Do homes need backflow testing?
Homes with irrigation systems, wells tied to city water, or certain fire systems usually do. Standard residential supply typically does not.
