RPZ Backflow Test

Service Description

We test residential and commercial backflow (rpz) valves online to irrigation systems and domestic water supply. We do not test valves online to fire systems. The Illinois Plumbing Code requires that a backflow prevention device be installed on all (Commercial and Residential) irrigation systems to protect the potable water supply. The law not only requires the use of backflow prevention devices, but also that the devices be tested once per year.
