Hunter Technical Support Document
Why is my sprinkler not popping up?
|Pop-up sprinklers require water pressure to “pop up", a broken irrigation pipe or a worn sprinkler wiper seal can cause a loss of water pressure.|
To determine whether or not your pressure needs to be assessed or replacement parts may be necessary follow these couple steps.
If the riser stems pull up relatively easy then it may be a pressure issue and the system's hydraulics would need to be assessed.
If the head struggles to pop up even with manual assistance than the riser seal and stem itself may need to be replaced.
