Currently replacing the overflow gasket in jacuzzi tub but I’m running into an issue. I’ve never seen an overflow system like the one I have in the tub which is a turn style overflow system. First of all, the overflow tube extends from the hole and into the tub approximately 3/4 of an inch. Secondly, the old overflow gasket is located in the overflow tube but behind the tub which makes it impossible to remove and replace. Not sure how to replace the overflow gasket without tearing up the tile that surrounds the tub or installing an access panel in the tile. Can anyone please help me out with ideas? Thank you...
