Irrigation Backflow Preventer Assembly

At Rainbow Irrigation & Backflow Prevention, Inc. we don’t mind if our clients still think of us as a service company.

When we opened our doors in 1995 we took a lot of pride in offering service strictly for irrigation systems. The irrigation side of the business was the cornerstone of our company until our 2003 expansion into the Backflow Prevention business.

Rainbow Irrigation & Backflow Prevention, Inc. does NOT perform the actual installation of irrigation systems. However, our services include turn-on, repair and winterization of all irrigation systems. We also install, repair, and certify Backflow Prevention RPZ devices for irrigation systems according to local and state regulations.


Clients who are planning to add an underground sprinkler system should always plan for what added expense?

The need to install a Backflow Preventer Assembly Reduced Pressure Zone (RPZ) onto your underground sprinkler system. Illinois plumbing code 890,1130 b: “Approval of Devices and Maintenance…” also requires that Backflow Prevention Devices be maintained and tested annually by a licensed cross-connection control device inspector (CCCDI).

Keeping our water supply safe is a serious business and at Rainbow Irrigation and Backflow Prevention, Inc. we consider our work to be a sacred trust. That’s why we make ourselves available 24 hours a day for any Backflow Prevention emergencies that you may encounter.
