How do I get a skimmer adapter plate unstuck from the skimmer after manually vacuuming the pool?

Question

After reading several items on the net, looks like i should have put the adapter on top of the skimmer basket, instead I took th basket out. Now it's really stuck. I even tried pliers to pull it out, but can't. Yes the pump is off.

Answer 1

maybe a poolman with a CO2 bottle can blow it out from the pump....you may have to plug the hole in vac plate somehow
