Impact sprinklers not rotating properly
when i turned the sprinklers on mid may all of my impacts seemed to rotate fine and all worked properly. since then only a few on each stations actually work properly. I moved into this home a few months ago. on one station is 2 rainbird maxipaws and 2 orbit satellites impacts. After adjusting the spring on the maxipaws they work great now, but the orbit satellites will turn all the way to one side and not trip the pin. And on another station i have the same problem with 2 more orbit satelittes. They are older, probably at least 10 years old. Where should i go from here? replace with more impacts, like rainbirds? Or can they be fixed? Can they just be wearing out and not getting enough pressure as in the first of the season when everybody wasnt watering as much?
