I recently purchased a Polaris turtle 66 vacuum for my above ground 24/52 pool and the return we have is an eye type that doesn’t fit the return. We have not been able to find or make a coupling. It appears to be a 1 3/4 x 1 1/2 which seems odd. Has anyone had this issue. What did you do? I am thinking only option is to drain water down and put in different return. Any help is appreciated.
