Hunter 4″ Pop‑Up with Integrated Nozzle – No Separate Nozzle Replacement

Expert Advice

These heads have the nozzle molded into the riser; once broken, the head is done. If the same model is still sold, you can swap the “guts” (cap and riser) without digging. Otherwise, replace with Rain Bird 1800 series spray heads with removable nozzles—future clogs or pattern changes only need nozzle swap.
