Meet our Team

Derek Biba Founder

My wife and I started a Backflow Testing company in 1994. We purchased test Gauge in 2000 in the hopes of simplifying the process of obtaining services related to Cross Connection in the Chicago market. 20 years later through a series of Franchise partners our team hopes to take that same message to other locations. 

When not immersed in Backflow Prevention I enjoy hanging out with family and friend son the weekends and vacations. Bumming around the house and office working on things.

Hobbies include but are not limited to: skiing, paddle boarding, riding my bike, and any live music I can find. No longer golf cart rides - way too dangerous

When I am not working, I am spending time with my husband and 2 kids (Sophia 9 and Emmett 6). We love spending our summer nights at the dirt race track. One of my biggest hobbies is BBQ. I love coming up with some fun new recipe on the grill, and of course snapping some good food photos for Instagram!
