V1, Rainbird makes the "SA" Series of gear drive sprinklers. Similar to what you see. HD has them. Comment,, I'm with you morpheous. That layout of heads needs help. He must get a lot of rain because the yard is still all green. Either that or he ends up watering the street and house trying to stretch his coverage. Peace

In the early models of the module controllers some of them developed problems like you describe. If you talk to a local irrigation supplier they can tell you if your model is one of them and if the front panel is still under warranty for the free replacement.

I work for Toro. There is a picture in the following PDF of the Toro 570 ADJ Adjustable Arc Nozzle. I am not aware of any other adjustable arc models... unless you have an older one. But yours does not look like this. Depends on the age I guess.. But I have not come across any that look like that. I will keep looking. http://lautnerirrigation.com/docs/heads/To570.pdf

Karen, you can combine the micro bubblers and drip emitter tubing in one zone. Add up the flow rates of all the bubblers and emitters. The total shouldn't exceed the amount recommended for a zone with 1/2 inch tubing. That amount will vary depending on the size of the 1/2 tubing you have (there are several sizes of 1/2 inch tubing) . Your bubblers are adjustable so use the max for design purposes. If you have 5 bubblers at 10 gph that would be 50 gph. Then add in the emitter tubing. If you have 10 runs of emitter tubing and each run does 10 gph that would be 100 gph. Your total gph would be 150. You should be good up to about 200 gph
