 | Most people keep their green pasture watered with manual sprinklers. No one has come up with a pop-up that can take a horse or tractor on top of them. I researched, designed, and tested my pop-up sprinkler for four years and two months. |
| My other problem was low water pressure, so I had to have separate stations for each set of three sprinklers. |  |
 | Basically, I used a 4" PVC pipe end cap. |
| The pipe has a tall notch for the supply line. It sits on a brick. If this is pushed into the ground, it will not break the supply line. |  |
 | The pop-up is held in place. |
| For years people have unsuccessfully tried to irrigate their green pasture automatically. I succeeded. |  |
