Frequently Asked Questions
How often should I have my well serviced in Illinois?
Most state environmental agencies recommend annual well water testing and periodic system inspections. Given documented groundwater contamination issues in some areas, annual testing is especially important. Have the system mechanically inspected every 3-5 years.
What does routine well maintenance include?
A routine well maintenance visit includes visual inspection of the well cap and casing, checking the pressure tank and switch, testing water pressure and flow rate, inspecting electrical connections, and collecting a water sample for testing.
How do I find a reliable well service company in Illinois?
Look for companies holding an Illinois Department of Public Health (IDPH) Water Well Contractor license, or engineering firms licensed by the Illinois Department of Financial and Professional Regulation (IDFPR). Verify they carry liability insurance and have experience with your type of well and local geology. Your local board of health can provide a list of licensed well drillers in your area.
