We have had no problem going as long as 4 weeks without dumping our black water tank. The most important thing is to have plenty of fluids in the tank to create a heavy enough flow to wash the solids out of the tank.

If you must dump before black tank is at least 1/2 full, then add water to at least 1/2 full, and then dump.
