pump will only prime when basket it out

Can we just run the pump with the bubble? It's not a huge bubble, as you can kinda see from the photo.

I run mine (a Hayward) with small bubble like that. It appeared a 2-3 years ago, and I figured as long as it was not cavitating it was okay.

Out of curiosity, have you changed any plumbing lately? Just wondering if there is a place in the plumbing that can trap the air that forms the bubble.
