Nolte and Sons handles Backflow Preventer Testing. Iowa State law requires that all backflow devices be inspected annually. Contact us to inquire about testing. Most residential tests can be done without any appointments if the valve is located outside.

  • Testing and certification of existing backflow devices
  • Cleaning the valve is a normal part of the test
  • Sending all necessary reports directly to your municipality for you
  • Reminding our customers annually of their next annual test date
  • Guaranteed compliance with state, local, and EPA laws.
  • Skilled, certified and professional backflow testers
