A common misconception is that retic should run for 10 minutes.
NOT SO!
You are allowed to apply 10mls of water on your watering day. This is where the confusion comes from.
10ml not 10min!
So different nozzles require different run times.
Normal Toro – 10-15 minutes
MP Rotators – 45-60 minutes
Gear drives – 20-40 minutes
(The difference is related to the spacing between the sprinklers.)
But don’t buy the 10 minutes thing!
