How can I effectively reroute my sprinkler lines to optimize the irrigation system in my garden?

To effectively reroute your sprinkler lines to optimize your garden's irrigation system, first, plan the new layout to ensure even water distribution. Then, dig trenches to lay the new lines, making sure they are sloped correctly for proper drainage. Connect the lines to the existing system and test for leaks before covering them back up. Adjust the sprinkler heads as needed to ensure complete coverage of your garden.
