Of course, whilst the OP was sitting on the toilet, he could have read
the packet of the wipes, which clearly (at least on the packet I have,
it does) that you should not flush down the toilet, but dispose of in
the bin.

OP specifies Andrex. My packet of Andrex Moistened states they are
'flushable'.
