I have a 90-something Hot Spring Highlife that is leaking. The leak presents itself through a hole in the pump compartment where some plumbing comes through (indicated with a red arrow). The local Hot Spring dealer gave me some epoxy to seal the lens but that didn't stop the leak. I have the tub on its side and have begun removing foam, but I have yet to find any plumbing. A diagram would be most helpful. Based on where the leak is showing, is there any plumbing in particular that I should be going after? Thanks.
