As stated earlier don't leave black water open. I may run the gray open but a day or so before dumping the black tank I'll shut the gray then later dump the black first shut the black valve and dump the gray tank to flush with. When it is a one night stop over both are shut until we are ready to leave and I may not dump the black to stir up the solids.
