Professional Inspectors

Whether your backflow preventer needs cleaning, or is not functioning properly, the plumber acting as a backflow inspector may not have the experience or knowledge to fix the problem, if they even catch it at all! This is not, and never will be the case with Chicago Backflow. Each and every time you schedule your backflow test and certification with CBI, guaranteed your inspection will be completed by a fully licensed backflow inspector that ONLY tests, certifies, and repairs/installs backflow preventers. Backflow testing is CBI’s specialty.

A photo from the early days of CBI

Backflow Industry Trailblazers

When the Safe Drinking Water Act was federally mandated (1974), the need for testing backflow preventers became more prevalent. Mandated annual testing became a vital part of the initiative. Mike Eisenhauer, current owner of CBI, was one of the first to adapt and dedicate his business to this expanding field. He was committed to applying his plumbing knowledge to train the best backflow team available, so they could provide the top tier field work and customer service. The initial committee for safe water and backflow prevention was formed in 1985 and comprised a team of five people. Being a part of that committee helped build the foundation for the small family-owned plumbing business that was Eisenhauer Plumbing to evolve into what Chicago Backflow is today.
