Hello everyone!!! I'm in the process of installing a new Hayward DE filter to my Intex 24' round pool, and also I would like to upgrade the plumbing to pvc 1 1/2 plumbing. My problems is that I need to eliminate the Intex plunger valve and replace them with regular ball valves. How do I do this? Thanks!!! There are some threads addresing this very same problem, but for some reason the pictures are not visible. Thanks!!!!
