I used a trick I saw here and added three bags of ice to the black tank and took the rv for a drive. Then when i emptied the tank when I got back, it emptied fully. Yay. My RV is under warranty and I am waiting for parts to replace the shutoffs for black and grey tanks. You probably have gotten yours fixed by now but I thought i would send you what worked for me at the time.
ALWAYS good to post "what worked" posts to help the multitude who may have the problem but not posting about it................adding to the forum knowledge base!!
