Sprinkler head won't rotate automatically
Hi,
I just have had one of my sprinkler heads stop rotating back and forth in the 180 degree arc that it used to. When the sprinkler comes on, all the other heads do their sweeps according to their angle settings. This one pops up and sprays fine but does not sweep back and forth. When the sprinkler shuts off, it retracts ok. I can turn the top part by hand when it is popped up and point it in any direction as it sprays. The sprinkler head brand is K Rain. Any suggestions?
