Water Flow & Backflow Prevention

Water Flow Information


Water flow data can be obtained from the Wheeling Fire Department Fire Prevention Bureau during regular business hours. In the event that a new water flow test is required, please allow 3 working days to process your request. Water flow tests may only be done when the outside temperature is above 32 degrees Fahrenheit and rising.

Back Flow Prevention Device Requirements


The Illinois Plumbing Code and the Village of Wheeling Plumbing Code both require the installation of a certified reduced pressure backflow device with metered bypass on all fire sprinkler systems. All backflow prevention devices must be UL listed, FM approved, and/or ASSE listed for use with Fire Sprinkler Systems. For specific requirements, contact the Village of Wheeling Plumbing Inspector at 847-459-2620 (Community Development Department).
