Backflow prevention devices protect the public water supply from contamination, and in Ivanhoe, IL, annual RPZ testing and certification is required for properties with irrigation systems, boiler fill connections, and other cross-connection risks. Failing to test on schedule can result in a compliance notice from the municipality or water provider — and in some cases, water service interruption until certification is on file. H.T. Strenger has served Northern Illinois since 1911 and provides licensed RPZ backflow testing, certification, and repair for residential and commercial properties throughout the 60060 zip code.
Ivanhoe’s large-lot properties create more backflow risk than typical suburban developments. Large irrigation systems covering estate-scale landscaping, private well connections, farm and stable plumbing, boiler systems in large homes, and commercial-adjacent plumbing all require properly installed and maintained backflow prevention assemblies. A device that fails its annual test is a compliance violation — but more importantly, it is a real risk to drinking water quality. H.T. Strenger completes the certified test, provides the documentation your municipality or water supplier requires, and handles any repair or rebuild needed to bring a failing device into compliance.
Call H.T. Strenger at 847-234-9440 for RPZ backflow testing and certification in Ivanhoe, IL (60060).
What Backflow Prevention Protects in Ivanhoe
Backflow occurs when pressure differential causes water to flow in the wrong direction — pulling irrigation water, boiler water, or other non-potable sources back into the drinking water supply. An RPZ (Reduced Pressure Zone) assembly prevents this with two check valves and a relief valve that activates if either check fails. It is the highest level of backflow protection and is required on most commercial irrigation systems and many residential irrigation systems throughout unincorporated Lake County.

– Properties with in-ground irrigation systems tied to the water main
– Homes and facilities with boiler systems using make-up water connections
– Commercial properties, farms, and stable facilities with multiple water uses

How H.T. Strenger Handles RPZ Testing and Service in Ivanhoe
Annual Certified Testing
Our licensed testers use calibrated gauge equipment to measure check valve seating and relief valve activation in accordance with ASSE standards. We complete the test report and submit certification documentation to your water supplier or municipality.
Repair and Rebuild
If the device fails testing, we can perform on-the-spot repair in most cases — replacing internal seals, springs, and check valve components. Full device replacement is recommended when the assembly is too corroded or worn for reliable repair.
