Dirt in Sprinkler Heads After Head Replacement: Flush the Line

Clearing Dirt from Lines After Sprinkler Head Changes

Changed inefficient heads, dirt got in line, now clogging previously working heads. Best flush method?

Pro Flush Procedure

1. Clean all affected heads (remove, rinse screen/nozzle).
2. Go to last head on the zone.
3. Remove it. Attach hose with fitting to the riser.
4. Run zone 30 seconds—water flushes out hose.

6. Test and readjust all heads.

Standard practice—even pros do this.
