I bought a 14ft round Intex pool. I figured from last year that the pump that comes with it doesn't really work. I bought a 4000 gph pump also made by Intex We tried lastnight to use the connectors and get it all to fit and only got frustraded. The pool is filling now but I think I figured it out. I pray that I did so we don't have water leaking everywhere. We will see when the pool is finished filling probably on Sat.
