How To: Change a Sprinkler Nozzle (Part 2)
 - Video Transcript, Demonstration by Peter Gallagher

The items that we will be using for today's project include an assortment of nozzles, and then the tool for the appropriate nozzle, and then finally there's a collar. You can find these tools at a local dealership that specializes in irrigation equipment or at someplace like Lowe's or Home Depot.

Alright. So, now we're in the field, and this head has already been installed. So, it's in the ground, and what I need to do is change the nozzle on it because I did have the wrong size nozzle initially. It's probably a number 2 nozzle, and that wouldn't be big enough for a 360 degree radius - which is what we are using. Instead I'm going to put in a number 6 nozzle, so I've selected a nozzle. It's a number 6 nozzle.

And, we are going to go ahead and use the little tool. This happens to be a K-Rain. So, I'm gonna use the tool for picking that up. We'll lift it out of the ground, and in order to make it easier to make that installation, I am going to go ahead and use this collar to hold this in the upright position. So, I'll set it down here, and it's going to drop down to the point where it hits the collar. So, it's going to be hard to see.

So, I'm going to unscrew the little set screw that's in there until it gets to the point where I can remove the nozzle. It feels like it's up high enough. I'll take a quick look at it. I think I'll lift this up. What we do is, we'll grab the nozzle, and then just kind of gently pull it out. So, there's the old nozzle, and we'll take the new one with the little wings up toward the top - the tabs. And, that screw of course has to go in where those tabs are. So, we want to make sure that we put it in so that it kind of lines up with the screw tabs. So, it's right about there, and then we push it in all the way. Such that when we turn the screw in it will hold that in place. I'll turn this around, and then we'll look at it to see that it's going to the right place. Push it in a little further. Okay. I'm going to keep going. Uh, looks like that's down far enough to hold it in place. Shouldn't be any problem. I'll take the collar off and let it pop down.

So, that's the way we adjust the irrigation heads. I'm Peter Gallagher with State-by-State Gardening.
