Skimmer not sucking water

I have an ungrounds pool with one skimmer. The pump was replaced 6 months ago. My skimmer stopped sucking water. There is zero water rotation in the basket. I thought it was a clogged pipe so I used a drain King and some pine needle came out, but there is still zero circulation. I’m really don’t know what to do. Everything seems to be working.

Thank you for contacting Inyo. It’s possible that the valve controlling the skimmer line was closed. Have you tried rotating the valves that are in front of the pump?
