CAN I BECOME A CCCDI BACKFLOW TESTER WITH A CHICAGO PLUMBER'S LICENSE?

QUESTION: To be a CCCDI does a plumber need to have a plumber’s license issued by the State of Illinois or will a City of Chicago plumber’s license suffice??????????????????????????? BACKFLOW COMMITTEE REPLY: Illinois acknowledges and accepts both the City of Chicago Plumber License as well as the Illinois Department of Public Health (State of Illinois) Plumber License when requesting CCCDI Certification.

WHAT BACKFLOW TEST READINGS SHOULD I HAVE?

QUESTION: I have a test report showing test values of 3.6 PSID across the first check, 3.4 PSID across the second check and 2.0 PSID relief valve opening. When I entered these values into my backflow tracking program it showed this as a failed test but the tester marked it passed. Can you explain?????????????????? BACKFLOW COMMITTEE REPLY: Your software flagged this test as FAILED because the first check valve reading must be above the relief valve opening point and ≥ 5.0 psid.
