J-9 Sprinkler Extensions - No Digging Needed!
J-9 Products of Western Colorado, LLC is owned by Scott and Janine Mullin, who live in Grand Junction, CO.

J-9 Products is currently offering just this one product, J-9 Sprinkler Extensions, developed to be compatible with Rain Bird® pop-up sprinklers. Designed as a DIY pop up sprinkler repair kit, J-9 Sprinkler Extensions contain a coupling and a riser. They come in 3 sizes, which can be combined to raise your sprinkler to the exact height you want, and are patent pending.
