i installed a type 2 Octopus pump . I am getting a lot of chatter when I jog the pump. It goes away after a few seconds of running . Then the pump is fine. After a few minutes at rest the chatter is back. This does this most all the time. The first 1-2 seconds of running it chatters then clears up. It is not the pump or air. Both have been eliminated. I feel it is the sea star helm causing it. I did mount the pump right under the helm. Did I put it too close? Should there be more the 1’ of hose between the helm and pump? I can move it if needed.
