Storing with blank tanks 1/4 full???

[512Climber]

So here's the story. We went camping this week at a place with no sewer hookups so I couldn't flush out blank tank before we left camp. We have another trip coming up in two weeks. I was wondering if we could wait until then to dump and flush the black tank. I searched around and couldn't find any definitive answers so I figured I would ask the internet at large.

How long can you leave waste in black tanks? What can go wrong if left for say a week? A month?

Tell me your horror stories if you have them or your triumph of dumping 3 month old poop without any issues.

Yes this is a serious post but thank you in advance for the laughs that I am sure will ensue.

I have gone over winter with the tank 1/4 full. just add a bit more water when you go to leave so it will swish around and dilute a bit more on the drive and then dump it when you can. I try not to do this, but it happens once and a while

If there isn’t a gas station or truck stop in your neighborhood to dump, I would suggest adding another dose of black tank chemicals in the next week.
