I took apart the original filter system that came with the pool and replaced it with a sand filter system. The only part I didn’t have was the skimmer. I purchased that from INYO POOLS installed it and now I crystal clear water

I totally replaced the whole unit. Took the screws and gasket off the broken unit. I had to unscrew the bottom threaded pvc connector and screwed new one on top with pipe thread to make it water tight. Everything went back together very good

Make sure you watch the videos for the correct installation. If you aren't careful about the order you tighten the screws you will end up with leaks. It's difficult to correct the error but it can be done.
