Renewal window opens July 1, 2023.  You will not be able to renew before that date.

  • An Iowa HHS approved 5 hour BPAT recertification training course is required to renew.  This course can be taken any time during your 2 year renewal period. Your training provider will upload your certification in our database. If the course has not been uploaded, please contact your training provider.
  • You can also renew if you have a current third party certification from either American Backflow Prevention Association (ABPA) or American Society of Sanitary Engineers (ASSE). You must provide a copy of your card or certification.
  • Late fees start on October 1st to allow program staff time to process renewals before the October 31st expiration date.  The late fee is $10 per month.
  • A backflow registration can be inactive for 2 years and can still be reinstated.  If it has been more than two years, you will need to retake the Iowa HHS approved 32 hour BPAT training course.
