After becoming jealous of seeing all the other Intex users on this forum with thru the wall skimmers, hard plumbing, and fountains, I finally gathered up enough courage to do it myself (most of that courage came in liquid form.) I'm not sure if this was the "right" way to do it, but it's what I had envisioned and I went through with it. I decided to use the original side wall drain along with the skimmer by plumbing them both to a 3 way Jandy valve. I also added another return and a fountain. I realize the extra return was probably unnecessary. But hey, this whole project was overkill, which is the whole point now isn't it? The fountain is actually a modified one that I got from Walmart. It's supposed to attach to a return on the inside of the pool, but I plumbed it to the outside with its own shutoff valve because I didn't like the idea of having it inside where someone could easily bump into it. I've never worked with PVC before and I guess I didn't have the fountain plumbing aligned just right when I glued it, so it looks a little off. But it still works. I don't want to jinx myself, so I'll say with reservations that I'm cautiously un-pessimistic that I might not have done a bad job
