Trying to figure out why the pump basket isn't filling. The only time it does is when I pour some water in so it can prime. I've checked to make sure the impaler isn't clogged by sticking a screwdriver in to feel if it turns, which it does. The pool vacuum seems to be working. Seems to prime fine once I pour the water in but once I shut it down the water starts going down to maybe to where it's only a 1/3 fill.
