According to the PA Safe Drinking Water Act, Title 25, Chapter 109.709, it is the building owners responsibility to provide functioning backflow prevention devices to prevent contamination of the public potable water system. If you do not have a backflow preventer, or you do not get your preventer tested annually, your water company will discontinue your service.
