Before you get full of poo try this. Completely empty the black tank and then dump a few bags of ice cubes down the toilet and then take the TT on a long ride preferly alond a windy road. The ice cubes should slide back and forth and help loosen up stuff. I would then fill the black tank with plenty of water and dump it several times.
