Got a lost sprinkler head?

A sprinkler head that is not popping-up but is not leaking a lot of water can be tough to find. If you can't find it, you can't fix it! So what do you do?

Well, first of all, you need to get in the general vicinity of the sprinkler head. If you already know about where it is but you cannot find it, simply use a hard rake to find it (read more about using the rake below).

You can usually do this as long as the sprinkler head is spaced the same as all of the rest of the heads on that zone. So, first you need to figure out how far apart the heads are spaced (you may get a little wet).

Here is how you find the spacing:
  1. First, go to the timer and manually turn on the zone that the rogue sprinkler is in. After the heads are all popped-up and spraying, step off spacing between each working sprinkler and come up with an average number of steps between each.
  2. Now, step off this average number of steps from the surrounding sprinklers toward the rogue sprinkler, marking the area with a stick or rock or something.
  3. You should have a good idea of where the lost sprinkler is now. So grab a hard rake (not a regular rake, the kind with the short, hard metal ends) and drag the rake in rows across the area, while applying pressure to the rake head. Now, if you run over the sprinkler head with the rake, you will know it. Your rake will either come to a halt or you will feel it hit the sprinkler head.

I tried your method of tracking down a lost sprinkler head. Unfortunately, my efforts didn't pay off using a yard rack. However, I did have excellent success by turning on the sprinkler zone where I thought the lost sprinkler head was in. I went to each working sprinkler head in that zone and turned the water off. By adjusting each head in the zone I was able to create sufficient water pressure to pop up the missing sprinkler head. After finding the missing sprinkler head I went back to each sprinkler head in that zone and turned the water back on with an adjustment key (Hunter sprinkler system).
