Purchased a new home with Weathermatic system installed by builder less than 2 years ago. One of the T3 rotors (with arc adjust) closest to the house appears not to be able to adjust the arc. It spins completely around, no matter what the setting is on the arc adjust - which would be no problem in one of the open areas of the yard, but it's right next to the house and sprays the brick foundation. Is there a way to open it to see the gear assembly to troubleshoot/fix, or is my best bet to simply buy a new sprinkler head?
Thanks in advance for your help
