Single Sprinkler Head Not Getting Water

One head (last on zone) has water in the pipe but none discharges. No visible leaks. Rest of zone works. Happened at spring startup.

Clearing the Blockage

Backflush: Insert a hose into the head's threaded fitting and force water backward against normal flow.
Probe the Line: Push a wire or electrician's fish tape down the pipe to locate the obstruction. Measure depth to minimize digging.

If these fail, dig at the located spot to repair or replace the lateral section.
