New member here-got a question. I just replaced my Cornelius 18x44 pool with an Intex Ultra Frame 16x32. I'm planning on using my existing equipment instead of what Intex supplied. I also have a main drain in the bottom and an existing thru the wall skimmer. My pump/filter is a Pentair Whisper flow with a 36sf DE filter. I've seen where the thru the wall skimmer is cut in, so I really have no problem with that. But I haven't seen where anyone have installed a main bottom drain/suction on their Intex pool. I don't really see a problem, except for the fact that I'm cutting a hole in the bottom of my pool. Any help would be greatly appreciated.
