If you have an irrigation system, most Chicagoland municipalities require annual RPZ (Reduced Pressure Zone) backflow testing to protect the public water supply.
RPZ testing may also be referred to as RPZ certification, backflow certification, CCDI certification, or general backflow testing, depending on the municipality and local regulatory requirements.
Carefree Systems provides certified RPZ testing, documentation, and compliance services for residential and commercial properties.
An RPZ (Reduced Pressure Zone) device prevents contaminated water from flowing back into your, and the public's drinking water supply.
Annual testing ensures:
✔ The backflow device is functioning properly
✔ Your irrigation system meets municipal requirements
✔ Your property remains compliant
✔ The public water supply stays protected
Most cities require proof of certified testing each year.
You likely need annual RPZ testing if you have:
• A residential or commercial lawn irrigation system
• A large landscape irrigation setup (any system should have an RPZ)
• Certain plumbing cross-connections (pool or pond fill, fire suppression, etc.)
If your municipality has sent you a notice — testing is required.
We keep it simple and efficient:
1 A residential or commercial lawn irrigation system
2 Results are documented and returned to our office for submission
3 Carefree then submits test results to your municipality for compliance
