They will counter with a tank rental bill, of course.

Just to be clear, I have no intention of asking *them* for rental
and, I certainly hope they have just as little intention of asking
*me* for the back rent.

In my case, back rent would likely exceed the cost of the tank,
so, I would just tell them to take their tank back.

Then I'd put in a new tank, but, at least I'd have clear and
free title to that new tank.
