Black water rank

[chapmana.0216]

The last time we went camping was late August. Circumstances caused us not to be able to flush the tank after short trip. Black and gray tanks been sitting there since mid August and just remembered we didn’t get it flushed out. What should we do?

Flush them, just be ready for some foul smells. I've had to dump tanks from trade-ins that were full of "stuff" and sat on the lot for months.

We fill dump at least twice at the end of the season but the dump station is less than a block away. I can pump out in the driveway but the dump station makes it go faster. Second time just fresh water to the top of both tanks then let her rip.

When I've really foul tank problems in the past I find filling it completely with a bunch of chemicals and water, and letting it sit for a week or two works well. If you can flush/clean it right after emptying it it's also very effective since everything is super loose after being submerged for a week.
