Would an air pocket cause a problem with the pump? I was vacuuming the pool and the hose popped open. A bunch of air sucked into the pipes before I could shut it off. I have a leaf catcher attached to my vacuum so I don't think the pipes are clogged with leaves. Could I force out an air pocket with a plunger? Or should I push a hose down the intake pipe and force water in there? Any suggestions?
