I have been doing a lot of trenching and digging in my yard in service of a rock border project that has been going on for months now. One result of that project has been a lot of sprinkler repair. I have broken pipes underground while cutting up roots, and tried to dig straight through hidden sprinklers. That plus regular sprinkler maintenance has been a new chore for me. The last house didn’t have them and I am learning on the fly what I have and how to fix it.
Most of this is pretty routine plumbing, but repairing or replacing sprinkler heads is a bit different. They are buried, and often very overgrown with grass. Once you get to them, they tend to be tough to pull out of the ground. To help with all this I 3D printed some tools.
First up is a large hole saw looking device. A 1/4-20 bolt fits in the center and gets chucked up in a drill. It has a 3in ID which encompasses all my sprinkler heads. I had a sprinkler that needed to get an extension put on it, so I used it as an example. The bit breaks up the soil and grass around the sprinkler head making it easier to fully expose and extract.
Even with the grass broken up it is still hard to get a hold on those sprinklers without doing a lot of digging. To help with that I made a tool that grabs onto the ribs around the head and provides a good handle. It made extracting the unit very easy.
That one is designed for a Toro 570 series sprayer. I also have some Hunter PGP sprinklers that rotate on their own. Those are a lot bigger and require a different tool to extract. All the designs are bundled together on a single thingiverse post.
