A Plumbing permit and a Backflow permit are required for any new construction, alterations, additions, and/or other types of plumbing work performed in relation to a backflow device in the City of Harrisonburg. If a backflow device will be installed as part of a Fire Suppression permit, a Backflow permit will also be required. There is no additional charge for a Backflow permit associated with a Plumbing or Fire Protection permit. A permit is not needed for testing the device.
