New Jersey Physical Connections Regulations
NJ Backflow Prevention Regulations are set by the New Jersey Department of Environmental Protection. NJ State Law regarding the testing and maintenance of commercial backflow preventers states, “Testing must be completed by a certified tester with a valid backflow prevention device tester certificate.
New Jersey regulations require a physical connection permit be obtained by the owner of a facility containing an unapproved water supply and a public community water supply (Permits are not required for private residences). The permit has to be renewed annually and requires each backflow prevention device covered by the permit to be tested quarterly.”
