Blowing bubbles ... I mean, bubbles blow.
Tony:
What pump are you using? The Little Giant that I had was a source of consternation for the previous owner - he believed that it was introducing air through the pump housing, and had silicone all around the seams of the thing.
I think a likelier culprit was the PVC union seal, but we'll see. Once I install a custom acrylic receptacle under the return pipe, the bubbles 'should' diminish.
Then we're down to 2 possible sources: pump or pipe.
