In theory I have everything worked out plumbing-wise, while working on putting together my first AGP. No plumbing is installed yet, but I have all the perfect hayward matching unions recommended by hayward. It's just that I don't know how to connect 1.5" PVC to my skimmer and return, which appear to be set up for flexible pipe. The 1.5" PVC is just a little too small to fit on the fat end of the skimmer. Do I need extra parts? How do I make this work? Thanks.
