RPZ - Required Backflow Annual Inspections 2025

Notices were sent out early - Due by May 15, 2025
 
Residents and Businesses with Reduced Pressure Zone Devices (RPZ's)
 
RPZ's are required to be inspected annually to ensure the backflow prevention device is working properly with the RPZ tagged and a copy of that tag sent to the Village of Lakewood for Illinois Environmental Protection Agency review.
 
  • Residents with lawn sprinkler systems must install a backflow prevention device (RPZ valve) at their homes. Installation of such devices helps protect the public water supply from contaminants or pollutants that could back flow through service connections into the public water supply.
  • Fire Safety Systems. The installation of any fire safety system involving the potable water system shall be separated from the potable water system by a reduced pressure principle backflow preventer assembly (RPZ).
  • A swimming pool may have a direct connection with the water system for filling
 
RPZ valves must be installed by a licensed plumber and certified by a plumber with an IEPA Cross-Connection Control Device Inspection License (CCCDI) on an annual basis
 
 
Per State of Illinois Plumbing Code 77, Illinois Administrative Code 890 and Village of Lakewood Chapter 25 establishes requirements for the use, testing and documentation of Reduced Pressure Zones (RPZ’s) within water systems. 
 
Village ordinance and State regulations are designed to protect public health by preventing the back flow of contaminated water into the public water supply.  A sudden drop in water pressure could draw contaminants: chemicals, fertilizer, soapy water or even bacteria back into your pipes and the Village drinking water supply. 
 

Please schedule the annual inspection for your RPZ and forward a copy of the inspection report to info@village.lakewood.il.us, by May 15, 2025. 

 

If you believe you no longer utilize your RPZ(s), provide a letter from a State of Illinois licensed plumber that the RPZ has been removed and is no longer required by State of Illinois law, along with a signed RPZ Removal Affidavit.
