Yes, but it is also common for said people to get distracted. This results in a very messy flood in your rv.

I got distracted like this once with different results: (1) The result wasn't messy because the tank had been flushed well first, and (2) It wasn't a flood because the overflow ran out the roof vent. It taught me to not let myself get distracted during this operation.

(Some rigs have a sink or shower plumbed into the black tank, and they would have had a flood).
