skimmer butterfly gaskets

I’m replacing my 24ft above ground pool liner and the old style skimmer. Now the old skimmer had a gasket on the outside wall and then on the inside was the liner then another gasket then the face plate. On the new skimmer their using a one piece butterfly gasket if I'm looking at it right shows the gasket putting in the metal wall opening and the gasket sits on the outside next to skimmer and on the inside wall and the liner stays on the outside then the face plate over the liner so trying to say faceplate, liner, gasket, gasket on outside wall then skimmer hope I didn’t confuse you. Thank's

Yes Frank, that is correct. I install the butterfly gasket directly over the wall. This type of gasket was designed to protect the wall from rust around the skimmer area. I have seen instructions that call for you to carefully cut the liner first and then fit the inside of the gasket over the liner. I have never tried that because it looked nearly impossible. I saw another instruction book say to cut the liner from corner to corner twice. This would leave four triangle pieces of vinyl that could be wrapped around the wall and taped in place on the outside. The gasket could then be installed over the liner in that way. I have never tried that method either.

As long as the gasket is properly set you should not have a problem with leaks.
