rairbird/ hunter sprinkler heads not going down...

Ok well the other day i ran over a sprinkler head.....this hasnt happened in over 15years!!!! After hitting the head we stopped and looked for more heads that were up. Stepped/ popped down over 7 heads.

We ran the system and soe of the the sprinklers go down manually instead of auto.
I guess she just had the sprinkler guys out!
So i dont have to fix it. But im just curious why this is.... I pulled some of the grass back and they still dont go down..... Why is this??

A lot of times it's grit in the stems that's preventing them from going down. This happens often if the head is installed too low.

Other times it's Aged heads and are in need of replacement.
A cheapo person could take it apart, clean it, lube it up, stretch the spring some and probably would make it last a few extra years.

If the heads don't go down, even when you step on them, there's probably rocks in the bottom.

Low-drain checks take their time if it's a big zone.

Typically I would use some type of electronic valve locator.
You can also turn the valve on and off at the controller and have someone listen for the clicking of the valve solenoid (Make sure the water is off if you do this).

In addition you can poke around with a shovel/screwdriver in the area you think the valve is located. Sometimes there is a depression in the ground due to the soil settling where the excavation for the valve was done.
Also there may be a difference in the appearance of the grass over the valve box.

I've also seen some people successfully use a metal detector to find buried valves.
