OK I am struggling on finding where air is entering my system. A little background is I had to replace the the shaft seal on my Pentair Intelliflo VS. I followed it to the T, but now I am getting air in the system with no signs of water leaking. With no signs of water leaking makes me think it must be on the suction side. I have checked the filter basket as you will see there is no air in that, so it has to come in past that part is what I am guessing. I have looked every where changed the Ozinator value to make sure is was not the problem and still have bubble excessive amounts.
