Chicago Backflow was very professional from the office staff to the onsite technician. The office staff provided a time-window and Genaro, the technician called early and showed up on-time.
As a plumbing novice, I do not have much experience with backflows or plumbing. I highly encourage to opt for their $150 test/repair package instead of the standard $99 for first-time customers. It is slightly extra but if the backflow test were to fail, you might be quoted the standard price that will be substantially more.

Can always count on CBI for all of our backflow needs and certifications. Vito is the best!!

Mr. Doug Eisenhauer President of BSI

Thank you Mr. Eisenhauer.  Your backflow tester, James Kucala, Jr,  came

today and checked the Back Flow System at my home.  I received the report

from the Village of Orland Park showing it passed the test on June 13, 2022.

I am forever grateful for your continued thoughtfulness and generosity.

deceased at 97 years of age on March 18, 2021, is displayed on the lamppost

just as you enter the roundabout going North on Ravinia near the Village of

Orland Park City Hall.

The guys who came out to service our Backflow is just Awesome. Great guy who is very Professional, he is why he keep coming back to Chicago Backflow.

We used CBI for our backflow inspections. They were extremely responsive and quick to give us pricing. The technician, Mark, was on time, professional, quick, efficient and able to answer many question I had about our specific devices. Couldn’t have asked for a better experience. CBI had much better pricing than other companies in the area who we’ve used in the past. 5/5.
