The valve for the "waterfall" on my Jacuzzi has stopped working. I've not been successful trying to take it apart from the top to see if I can expose the failing valve. Is this possible? The second choice would be to disable it entirely. I've seen a schematic showing where it's connected to the plumbing inside the wall, but when I remove the outside cover I'm faced with a wall of insulation. Anyone have tips on best way to expose the plumbing and then replace the insulation?
