Our 301BQ has a black tank flush system. When we are back from a trip I normally flush (fill full & dump) the black tank 3 times before storing. I also use a "clear" elbow that allows me to evaluate the water coming from the black tank. BTW my storage lot has a dump station which makes it easy for me to do this.
