Still learning the ropes here about RVing and this forum has been a life saver in answering my many questions. We are at site (for 5 days) and the black water tank registers ⅔ full in my ACE 27.2 on the 4th+ day but the full light blinks once and goes back to ⅔. With us leaving in less than 24 hrs I hate to have to unhook to dump it and then back to rehook everything. I use the camp facilities but the misses refuses. My question is when the tank goes from 2/3 and then to full is there a “grace period” of a gallon or two? It seems like when your tank says ⅔ ( around 30 gallons of my 40 gallon tank) and then the light comes on for full there has to be a a little leeway.
