Backflow Testing & Certification


certified backflow testerThe Illinois EPA requires that a backflow preventer must be tested at least once per year. Depending on the type of backflow preventer, Indiana may require the device to be tested every six months. Chicago Backflow, Inc. (CBI) is a fully-licensed plumbing contractor. However, CBI does not perform the normal day-to-day functions of a typical plumbing company. Our specialty is plumbing in the interest of public health: we safe-guard your drinking water. We provide no other plumbing services than the installation and certification of all types of backflow prevention assemblies, ranging in size from 1/4 inch through 12 inch. Chicago Backflow is unique in that our Premium Backflow Service includes on-site testing and a complete backflow service and maintenance program for each backflow device certified for one full year! No call-back charges for cleaning or repair. We call it our "one call does it all" program. These EPA laws are in place to safeguard our drinking water, we are simply interested in making this process as hassle-free for you as possible.

Backflow Installation


A Story of Success

Water Tower Place, Chicago 
IllinoisWhen the Ritz Carlton / Water Tower Place fire protection sprinkler systems needed to be retrofitted with two 10" backflow assemblies, they called Chicago Backflow. With the Tower's 365-days-a-year occupancy, shutting down the building's water supply for any length of time was not acceptable. Therefore, there was only a two hour window to perform this monumental task. To make this task even more difficult, this would be the first time that the entire building's water supply would be shut off since its development. If not completed in time, a $1,000 per minute penalty would be assessed to the installing contractor. All other bidders refused to bid the project, stating it "just couldn't be done." Chicago Backflow performed this task with 17 minutes to spare. Chicago Backflow, Inc. (CBI) has been installing backflow devices for residents and business since 1993. If you have a backflow device, chances are that it was installed by Chicago Backflow. A CBI certification tag hanging from your backflow preventer is like a golden ticket -- all systems go.

Backflow Surveys / Inspections


Backflow Surveys

A system survey may be required by your city or state to collect the information on your existing backflow devices, such as the make, model, serial number, size, location, the system it is serving, and the test date. Once the survey is complete, Chicago Backflow will deliver the survey results to both you and your water district / municipality.

Backflow Inspections

Our staff possesses unparalleled experience in on-site inspections, backflow management and water quality control. Periodic on-site inspections of your facility are a vital part of your cross-connection control program, as they are essential in maintaining compliance with State and Local regulations, as well as OSHA regulations that mandate a safe, hazard-free working environment.
