Why RPZ Backflow Testing and Certification Is Required in Skokie, IL
Backflow prevention is not optional — it is a regulatory requirement for properties with irrigation systems, boiler fill connections, commercial plumbing, or other cross-connections to the municipal water supply. Skokie’s commercial density, multi-unit residential buildings, and active irrigation systems require annual RPZ backflow device testing to meet Village of Skokie and IEPA requirements. Failing to certify can result in compliance notices from the water department.
An RPZ (Reduced Pressure Zone) valve prevents contaminated water from being drawn backward into the public water supply if water pressure drops. The valve must be tested annually to verify its check valves and relief valve are functioning properly. A failed test means the device must be repaired or replaced before the property can be certified as compliant.
Warning Signs to Watch For in Skokie
- An annual backflow testing notice received from the water department or municipality
- A relief valve that drips continuously, indicating a failed check seat
- An RPZ valve that has not been tested or documented within the past 12 months
- Reduced pressure downstream of the backflow preventer
- Visible corrosion, mineral buildup, or physical damage on the RPZ assembly
- An irrigation system, commercial kitchen connection, or boiler fill line with no backflow protection installed
- A compliance notice or water service warning related to cross-connection control
How H.T. Strenger Handles RPZ Backflow Testing in Skokie
1. Locate and Identify the Device
We locate the RPZ assembly on your Skokie property — typically near the irrigation system shutoff, mechanical room, or commercial water connection — and identify the make, model, and current condition of the device before testing begins.
2. Perform the Annual Backflow Test
H.T. Strenger is certified to perform RPZ backflow testing using calibrated differential pressure gauges. We test each check valve and the relief valve per state and local requirements and document the results on the official test report form required by the authority having jurisdiction.
3. Repair or Replace Failed Devices
If the RPZ device fails testing, we repair or replace the assembly as needed. Common repair needs include fouled check seats, worn relief valve discs, and failed seals. We carry common replacement components to complete many repairs in a single visit.
4. Submit Certification Documentation
After a successful test or repair, H.T. Strenger provides and submits the required certification documentation to the appropriate authority — the water department, municipality, or building management — so compliance is properly recorded.
