Not sure what you paid for this unit. You need to seriously think of all financial factors. What it would take to fix. The main problem is do you know where the original leaks is or was. Sounds like it still might be leaking somewhere. Hybrids are notorious for leaks. In addition now you have the side walls to be concerned about. I certainly would let the manufacturer know; not that they will do anything with a unit this old, but just to let them know. Perhaps you might want to throw in the towel, sell what you have removed for parts and begin again. Sorry for your troubles.
