Hi

If heavier, non-dissolving T.P. has been used aboard by the previous
owner, I would of course have no way of knowing.

Assuming that the previous owner used it, what should be done to get the
crud out of the tank. FLush liberally with Fresh water a few times
perhaps? Is there some sort of additive that should be used to ensure
that the paper products dissolve sufficiently to come out during a pump out?

Thanks

M
