I do what mlts22 does:With both black and grey closed, I first dump the black tank then, with it's valve open, I dump the grey which also flushes the black tank. I do not have a macerator. I usually run a gallon or so water from the shower head unit into the toilet which helps clear the black tank. If there is a better way I need to know about it. My only problem is the black indicator level on the panel often shows the black is one third full when it is empty. I replaced the black sensor but still is quirky.

unless you replace the in tank sensors with those that are external, they will always be "quirky".
