I recently installed a new VS Intelliflo. The old pump did not have any bubbles in the basket area, but the new intelliflo has A LOT of bubbles, even at the highest speed. Its not just a lot of little bubles, but a lot of large swirling bubbles. From what I can see, it looks like they come in from the intake and swirl downwards.
The only difference at the moment on the intake side is where I cut the old PVC and installed a new stretch with a union. The old pump was straght from an elbow/valve to the pump (12" or so). Now from the same elbow/valve there is 4", union, and then another 4" into the pump.
When the manual recommends a straight 10-12" pipe on teh intake, does that incldue unions? Could this new union be causing this swirl of bubbles because its so close to the intake?
