Connecting drip irrigation to an existing underground sprinkler system (or retrofit) is a simple way to supply water to your drip irrigation system. Retrofits are commonly used to conserve water by replacing inefficient shrub sprinklers and bubblers.

To see how these items can be used, visit the Orbit installation guide. Sections 5-6 have lots of useful information.
