I am obtaining all of the parts and equipment to DIY build an 18-foot above ground pool with 2-inch Schedule 40 PVC. The only thing I'm having trouble with are the intake/return fittings. I can find them all day long for 1-1/2 inch, but I'm having trouble finding 2-inch. Hayward makes SP1408S2 that "might" work. It's not made for above ground pools, but it looks in pictures like I could adapt it to work. If you have knowledge of converting an above ground pool to 2-inch PVC, I would love to get your advice. THANKS!
