Some time ago, we expanded the grass area in the back yard to end at the same place as the concrete. The only problem was, the new area didn't get a lot of water with the existing sprinklers, so it was time for a change.
On the left is the old sprinkler location, with the new plug installed. On the right is the new location. It took a little investigating to figure out which of the six pipes I needed to tap.
Here's what the new installation looks like below ground level.
And here's the finished product. Hopefully this will help keep the whole lawn green.
