Use the "Interactive Selector" online to see if your sprinkler is part of the Voluntary Replacement Program. The Interactive Selector helps you understand the parts of each sprinkler model which you'll need to know in order to identify if your sprinkler is part of the Voluntary Replacement Program.
Choose "Download ID Brochure" if you would prefer to download a PDF which assists you in identifying whether your sprinklers are part of the program.
