Hi everybody, I am brand new to pools (first year) and things had been going great until we decided we needed a vacuum. This is going to sound dumb, but I am really struggling to figure out where and how to plug the hose for the vacuum in. We have a Bestway Power Steel 16' pool with a 1500 gph filter pump. It has two inlets and one outlet. My 1.5" hose for the Mainstays vacuum doesn't have the same type of connection that the filter pump has. Anybody have any ideas for me?
