We were dry camping in AZ and had to use "blue boys" to empty the tanks. I emptied the black tank and put in about 6 gallons to rinse it out. But nothing came out. If it came out at the first time how come it would come out the second? Then before we started home I emptied the tank at the dump station and filled it a few times with the sani-flush and it would flow real good but at the end it slowed to a trickle about the size of a garden hose and took at least 10 minutes for the rest to come out. Why at the end does it come out so slow? It makes no sense to me at all.
