Hi Jessica,

I wanted to let you and your bosses know that your technician Alan is an amazing man. He serviced my backflow last year and he was out again this morning. He is so kind and considerate of my property. He explains things and he is just a pleasure to be around. Not to mention that he does an excellent job, he is honest and he cares. In today’s world that is such a rare thing to find. I will use the services of Chicago backflow for as long as you keep great employees like Alan.

Thank you so much for your great service.

Fran Schultz

Chicago Backflow is a great company. They are very professional and have excellent customer service. I have been very pleased with the routine maintenance and fast response to emergencies. I will continue to use Chicago Backflow for a long time.

Anthony Graziani, Steger School District 194

The Elk Grove Park District has been a customer of Chicago Backflow for more than 15 years and in all that time, we have enjoyed terrific service, thorough repairs, numerous new installations, and fair prices!  Other companies have tried to lure us away with the promise of cheaper inspection costs, but the true value of Chicago Backflow’s service is in the warranty work they perform for us, often same day, and at no cost to us.

I highly recommend Chicago Backflow to anyone who’s serious about their water safety program.

John Walters | Building Maintenance Crew Leader, Elk Grove Park District

The CBI team continue to amaze us. John Keating had left our home only an hour or so after inspecting our backflow valve when your final report arrived by E- mail. That’s real efficiency. We want to thank Mike Eisenhauer, John, Jessica, Katie, Barb and the entire CBI family for your generous gift of time and skills. We can never thank you enough. We wish you and CBI good health and good fortune in all the years ahead.
