When is my backflow inspection due?

Backflow inspections follow a yearly cycle, and are due the same month every year regardless of when they were last inspected. For example, if your backflow is due in January and you don’t have it inspected until March, it will still be due in January of the following year.Backflow inspections follow a yearly cycle, and are due the same month every year regardless of when they were last inspected.
