Why does a sprinkler head stay up after the zone shuts off?
Short answer: Because something is keeping the stem from sliding back down. Dirt and debris around the sprinkler stem can prevent it from retracting normally when water pressure disappears.
A pop-up head retracts with a spring once the water pressure drops. For that to work, the stem has to slide freely inside the body. When dirt, sand, or grit gets packed around the stem — common in sandy soil, after a repair, or where a head sits low and soil washes over it — the stem drags and sticks in the up position.
A stuck-up head is more than a cosmetic problem. It sits above the grass where mowers, edgers, and feet can hit it, and a head that gets clipped while it is stuck up usually breaks. It can also keep dribbling water if the seal is not seated right.
The fix is usually to clean around the stem, flush the head, and check the wiper seal and spring. If the head is old and the stem is scored or the spring is weak, replacing the head is the better call — a new head retracts cleanly and the problem does not come back next month.
What we check in Summerwood
We check whether the head is stuck from dirt, a damaged seal, or a worn spring, and whether the head is sitting low enough that soil keeps washing over it. We clean and test it first, and if the stem is damaged we replace the head rather than leaving a head that will stick again.

Frequently asked questions
Can I just push the head back down?
You can, but if dirt is the cause it will stick again the next time the zone runs. The dirt around the stem needs to be cleaned out for the fix to last.
Will a stuck-up head break my mower?
It can damage the head more than the mower. A mower blade catching a stuck-up head usually snaps the head off, and then the zone sprays a geyser until it is repaired.
