I know not every PS is a fan of butterfly gaskets - I have one as well as just two generic individual gaskets. We have finished our rust cleanup primer repair around the skimmer opening and are ready to put the skimmer back on. I know that I need one gasket (or one side of the butterfly gasket) on the outside of the pool. Easy.
Question: Where should the inside portion of the gasket go - between the metal skeleton and the liner or between the liner and the skimmer face plate? Should I use the butterfly gasket between the metal skeleton and the liner with a second gasket between the liner and the skimmer face plate?
The reason I ask this is that the previous gasket (taken off by us) was a butterfly gasket whose inside portion of the gasket went between the metal skeleton side and the liner. I was expecting it to cover both the metal skeleton and the liner itself to ensure no water could ever possibly get down the side of the pool wall. Not sure if there is a right answer or one answer better than the next.... thanks in advance - Jeff.
