Dump valve came off in my hand. Need Fix. Video

Same as my 2008 981. Drop the bottom panel(s from the outside. Self explanatory when you look at it. Try reattaching the cable, but you might need a new knife valve. Its not hard. At least its not your black tank. This is a repair I would give to my RV shop, its doable for me, but I'de pass on doing it personally ,most likely. Less than 159 including the part to have it done.
