Common Questions
Backflow Testing in NJ — What Property Owners Ask Most
Is annual backflow testing required in New Jersey?
Yes — New Jersey Administrative Code N.J.A.C. 7:14B requires every registered backflow preventer on a public water supply to be tested annually by a certified tester. Test reports must be filed with the applicable water authority. Failure to comply can result in fines and water service interruption.
What happens if I received a compliance letter from NJ American Water?
A compliance letter means a registered device at your address hasn’t been tested within the required 12-month window. South Jersey Backflow resolves compliance letters rapidly — we schedule, test, and file within 3-5 business days in most cases.
Does my irrigation system need a backflow preventer?
Yes. Any in-ground irrigation system connected to a public water supply in New Jersey requires a backflow preventer and annual testing. Properties with chemical injection irrigation require an RPZ assembly under NJ high-hazard cross-connection rules.
Do fire sprinkler systems require backflow preventers in NJ?
Yes. Every commercial and multi-family building with a fire suppression system in New Jersey is required to have a DCDA backflow preventer protecting the potable water supply. These must be tested annually and reported to the water authority.
