Rotors will not rotate
Good evening sprinkler experts,
Did some searches through this forum but did not find any clear answers. If my question is frequently asked and I missed your answers in my search please excuse. Here is my question/problem. Now that it is sprinkling time again I noticied that I have a couple of my Hunter PGP sprinkler heads stop rotating back and forth. These couple of heads pop up and spray 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 as mentioned is Hunter PGP. Any suggestions for a DIY cleanout or repair? I want to try to fix first rather than replace.
Thanks,
Andre'
