I just bought a 2011 Hotsprings Grandee. Not sure what I got myself in to as this will take some work to get this thing up and running. The tub itself looks immaculate but is gonna take a lot of work. Im hoping that through this forum page that I'll have a chance! First question....Is this pink string supposed to be there? The previous owner (who could not get the tub up and running) did not know anything about this string.
