I'm dealing with what I think is a strange problem. I have small bubbles swirling in my pump basket. I check the black poly barb fittings coming out of the ground by flooding the area with water. I also regreased the pumps seals and ran water over them to check for an air leak with no obvious findings. However, when I remove the weir (a Jacuzzi strange floating type weir) and the skimmer strainer basket the bubbles virtually disappear from the pump basket. The only other time I see this phenomenon is when the sand filter is dirty and pressure is higher, I see almost no air bubbles in the pump basket. Am I trying to draw more water/pressure than my system will take?....is there a slight blockage between the skimmer and the pump??(a family member did clean the pool out without the skimmer basket in place last year). The communities thoughts are always greatly appreciated.
