RPZ (Reduced Pressure Zone) testing verifies that your reduced pressure backflow preventer is functioning correctly to protect your water supply from contamination. A certified tester uses specialized gauges to measure differential pressures across the assembly. RPZ devices are typically required for high-hazard connections.

Most jurisdictions in Illinois require backflow testers to hold a current certification from an approved training program, typically involving classroom instruction, a hands-on practical exam, and continuing education credits. Some municipalities maintain their own approved-tester lists. Always verify certification before hiring.

Residential tests typically involve a single PVB or DCVA device and are quicker to complete. Commercial properties in Glen Ellyn often have multiple assemblies, RPZ devices, and fire-line backflow preventers that require more time and specialized equipment. Pricing and scheduling may differ for each type.

Many certified backflow testers in Glen Ellyn will file test reports directly with your local water authority or municipality on your behalf. Confirm this with your provider before scheduling. Some jurisdictions require the property owner to submit reports, while others accept direct submissions from the tester.
