If this is the wrong place I apologize. I have a 16x48 intex with the small inlet/outlet fittings. I also have had given to me the larger through wall fittings. How hard would it be to change them and what is the best way to do it. I currently have the adapters with plunger valves. My pump is a Hayward super pump with a 3/4 hp motor, and a 200 lb sand filter and a through wall skimmer. Any pics or advice would be helpful.
