Lawn Irrigation Requirements

The Minnesota State Plumbing Code requires that a backflow preventer be installed on each lawn irrigation system. This is to prevent lawn fertilizers, weed killers and other contaminants from being drawn back into the drinking water system. A licensed plumber or the property owner must install the backflow preventer. A plumbing permit is required prior to installation.
