It may be better to swap out to a 6” head instead of these extenders.

 

Thanks for the reply. So are you saying to change out for 6" sprinkler body so that it will reach higher but leave the top of the sprinkler below grade?

 

I was referring to the bottom-inlet bodies which should bring the top of your sprinkler about 2.5” higher, along with the Additional 2” pop-up height. I’m assuming these are spray bodies you’re referring to (?). I have a similar issue where my sprinkler heads tend to settle down into the soil and by this time of year it affects me since my tttf is Max-height. I have mine on a flex whip with a 1/2” 90-ell inlet, so it’s just a matter of screwing old ones off and putting these in place. Sounds like your situation is similar (?).

 

If you need to raise ~1in, you can use the cutoff raiser with only the last section. More than one section break too easy.

 

Are they not attached to funny pipe? I installed all of my heads on funny pipe and will never have a problem raising them in the future.

Less than a week after I put in my system one of the heads got rolled over by a truck with both the front and rear tires....didn't even damage it.

 

@herein2023 - using funny pipe helps take pressure off the main line when you run it over, etc - as well as allowing flexibility in final head placement regardless of the lateral run - but that head will sink and need to get raised back up every now & then. It's a bit of a pain to support them in their ideal position once the compacted soil underneath them has settled. I've tried to push sand underneath them to keep them raised, which does seem more promising than using rocks or dirt. Since I need the higher pop-up height I think swapping them out is the way to go though. 2 birds/1 stone?

 

That makes sense, I didn't know heads sinking into the ground was a thing. I thought taller heads were only needed when letting the grass grow higher. I guess I can't visualize what would make a spray head sink into the ground unless maybe thatch build up?

I was thinking with the funny pipe you could just raise the heads and pack sand in underneath them, no swap out needed. I've had to adjust the height of a few of mine during the install and the funny pipe let me move up and down as much as needed that's why I asked about it.

 

Our head are not sinking but our ground level increases some from the small about of thatch(we bag all our mowing) and the 2-3" of dirt from the air that is left behind after a rain storm. Its amazing how much dirt is left in the gutters after a rain storm, I built separation boxes at the base of the down spouts because of this.

 

So each year my sprinkler heads are getting farther down, Avg right now 3" after cutting the grass. Right now I got approx 30 that are due to be raised. I am guessing the best way is to just dig each one up and raise it but I saw a kit at Home Depot called "Kap it" that looks way easier and less intrusive to the yard. So are there other kits like this out there and are they a good idea or do they somehow cause problems with the sprinkler assemble long term? Any thoughts or advise welcomed. homedepot.com/p/Pop-up-riser-extension-from-the-top-of-the-sprinkler-1-1-2-in-raise-Pop-Up-Extender-Kap-black-contractor-10-pack-KAP-10/313655827

The Kap-It works and is a fast and easy way to raise the sprinklers. The risers are 1.5 inches and the Kap protects the riser. The inner working of the head stay the same. Our landscape crews raise about 2000 sprinklers each season with the Kap-Its. We have seen very few problems with them. Once in a while they may stick but they just need to be flushed when they are running with water. We would recommend trying them out. I can tell you our techs like them because they raise each sprinkler in about 2 minutes with very little digging. They allow us to move onto the next job fast.
