Ok, call me crazy. I dewinterized the 32QB yesterday and I can't figure out how to open the low point hoses by the holding tank. I was able to empty the single hose directly underneath the holding tank but I can't seem to figure out how to open the two that are right under the camper by the holding tank. I can see the antifreeze but nothing seems to want to turn when I turn the hoses. What is the trick?
