Thats odd! In order to serve you better, i would ask you to take a look at the head, and tell me the make and model...there is a new head this year made by Hit Proline (another company similar to Orbit, that copies other products) and there has been a huge call back because they made the wiperseal soo tight they wont pop-up or retracts down.....they are called the Rainpro heads.....if they are the rain pro heads i would take out the head, see the pop-up size, and replace it with a Toro 570, because they use the same nozzle
Let me know!
