Who must test
- Non-residential customers must have an approved, working backflow assembly installed and tested as required, including on bypass lines and fire and lawn sprinkler systems. Source.
- Non-residential physical connections protected by a double check or reduced pressure assembly must be enrolled in the NJDEP Physical Connection Permit Program, which requires testing every quarter. Source.
Program
- New Jersey American Water runs a cross connection control program, required by NJDEP, to keep backflow from contaminating its distribution system. Source.
From notice to filed report, the steps are the same everywhere: how a backflow test goes.
