A backflow pressure test is typically required whenever there is a change in the plumbing system that could affect the performance of the backflow prevention device. This may include the installation of new plumbing fixtures, the replacement of an existing backflow prevention device, or the addition of a new water source. In some jurisdictions, backflow pressure tests are also required on a regular basis, such as annually or bi-annually.
