So in the meanwhile.......put at least 10 gallons of water + some more black tank treatment in there. It'll make the job a lot easier.
Potty Rule #1.....when you put in your treatment, whatever type you use, add at least 5 gallons of water. Potty Rule #2.....be overly generous with water after each use. Potty Rule #3.....NEVER have the valve open until you're ready to drain and flush. Potty Rule #4.....NEVER, NEVER leave the black tank sitting dry. You might get away with leaving the valve open in the grey tank - but don't do it - just watch and learn how long you can use the grey before you need to dump, then dump and close. If it seems like the kitchen or bathroom sink drains are running really slowly, STOP and dump. Otherwise it'll back and and possibly overflow in the shower....not good. Good luck.
