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.

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.

QUESTION THAT CAME FROM GEORGIA I only have one question. What type of backflow device need to be installed on a beauty salon that use hair chemicals??????????????????????? BACKFLOW COMMITTEE REPLY: Along with the backflow protection at the point-of-use as required by Plumbing Code, the site is considered a high hazard and an RP should be installed at the meter to protect your distribution system
QUESTION: We have a plumber that is a certified backflow device tester, working for a customer with a water operated sump pump. Currently there is a RPZ on the sump pump feed line. The plumber wants to install a double check device in place of the RPZ, he claims the rule has changed and this is a low risk installation. We don't agree. Can we require the RPZ? Has there been a change in the program making this a low risk installation??????????????? BACKFLOW COMMITTEE REPLY: The State of Illinois Plumbing Code does not specifically address water powered sump pumps. An Illinois-based battery backup sump pump manufacturer advertises heavily that an RPZ is required, as they want the customer to buy their product verses a water powered pump. The Backflow Committee has also discussed this topic on numerous occasions. The stance of the IDPH is that ground water is not a high hazard and a vented dual check valve is acceptable backflow protection for a water powered sump pump. Note however that being the water purveyor, you can still require an RP at the pump or at the water meter. State standards are a minimum and you have a right to enforce stricter regulations as long as you have it written in an ordinance, policy manual, or similar.

Backflow preventer tests are due either on the annual anniversay date of original installation or on the date assigned to them by the water purveyor. There is no written rule as to how many days before the due date a backflow preventer can be tested. As an un-written rule it is 30 days but should not be any more than 45 before the due date. Most water purveyors and/or their representatives will work with you if you are trying to make all of your annual tests become due at the same time or if you need to move test dates.

I installed a testable RP valve recently and now they tell me that the brass has turned white. It's in a chemical plant. Do you know why?
Yes - It happens especially quick when around chemicals. Brass is effected by the surrounding air and often turns white. Similar to how copper turns green. The environment around the backflow preventer is what's causing your issue. Sometimes it takes years, sometimes it happens quickly, sometimes it doesn't happen at all. This issue should not effect the operation of your assembly.
