RPZ backflow testing and annual certification is a compliance requirement for the majority of Lincolnshire properties. Lincolnshire’s combination of corporate office parks, hotel and hospitality facilities, large residential lots with irrigation systems, and properties with boiler and HVAC make-up water connections means that backflow prevention devices are widespread throughout the community — and every one of them requires annual testing to remain compliant with Lake County Health Department requirements and Lincolnshire’s water authority.

H.T. Strenger provides licensed RPZ backflow testing, certification filing, repair, and full device replacement for commercial and residential properties throughout the Lincolnshire 60069 area. Our licensed testers understand the compliance requirements specific to Lake County and Lincolnshire and complete the full process — test, report, and filing — in a single service visit whenever possible.

Why RPZ Backflow Compliance Is Especially Important in Lincolnshire, IL

Lincolnshire’s corporate corridor along Route 22 and Milwaukee Avenue includes office campuses, the Marriott facilities, restaurants, and mixed-use commercial properties — all of which have plumbing systems connected to irrigation, cooling, fire suppression, or mechanical make-up water that require backflow prevention and annual testing. A failed or untested RPZ device at a commercial property creates both a public health risk and a compliance liability that can result in fines or water service interruption.

On the residential side, in-ground irrigation systems are standard in Lincolnshire’s upscale neighborhoods. The RPZ backflow preventers on those systems are required by Lake County’s water authority, and the requirement to test annually applies regardless of whether the irrigation system was used heavily or lightly during the season. Lake County’s hard water also accelerates internal wear on RPZ assemblies — the mineral deposits and debris that affect internal check valves and relief valve seats can cause a device to fail testing even when it appeared to be working normally.

Properties in Lincolnshire That Require Annual RPZ Testing

  • Residential properties with in-ground irrigation or lawn sprinkler systems
  • Corporate campus buildings with boiler make-up water or HVAC connections
  • Restaurants and food service facilities on the Lincolnshire commercial corridor
  • Hotel and hospitality properties with commercial plumbing systems
  • Multi-tenant commercial buildings with shared mechanical systems
  • Properties with fire suppression systems connected to the domestic water supply

How H.T. Strenger Handles RPZ Backflow Testing in Lincolnshire

1. Scheduled Annual Inspection and Testing

We use calibrated test gauges to measure differential pressure across the RPZ assembly’s check valves and the relief valve opening pressure. Testing follows Lake County Health Department standards and Lincolnshire water authority requirements. We document all results and issue the certification report on the day of testing.

2. Compliance Filing with the Appropriate Authority

H.T. Strenger submits completed test reports to the Lake County Health Department and any local water authority required for the specific property. Commercial property owners and facility managers do not need to manage the filing themselves — we handle it as part of the service.

3. Same-Visit Repair When an Assembly Fails Testing

When an RPZ assembly fails the pressure differential test — which is not uncommon in Lincolnshire properties with Lake County’s mineral-laden water — H.T. Strenger can rebuild or repair the assembly during the same service visit in most cases. We carry repair kits for the RPZ models most commonly installed in the 60069 area, minimizing the time a property remains out of compliance.

4. Full Device Replacement for End-of-Life Assemblies

When an RPZ assembly is corroded internally, has failed repeatedly, or has been in service beyond its reliable service life, H.T. Strenger installs a new properly sized, code-compliant assembly and completes the post-installation certification testing required before the device is returned to service.
