Hello, I have a polaris 380, it has been in my pool for 15 years and the right side shell piece if coming off. (It is the 1997 model with
a two piece top shell.) I have replaced the shell screw recently and the shell piece that was loose as well, but the piece is still very loose. when I attempt to pull it out of the water the shell comes right off. I am sure the bottom base is causing the problem. it could be that the screw hole in the bottom base had warped or the hole was reamed. What should I do.
