I am about to get a replacement washing machine and noticed in one
manual that it states the old filling hose should never be reused when
the machine is installed. I can see that it /might/ be better to replace
it, (or at least replace the rubber washer where it screws onto the
washing machine inlet) but if it is not leaking why is it essential to
replace it?

I must say that looking through specs and reviews of washing machines is
quite possibly the most mind-numbing and madness-inducing activity I've
experienced recently. Too much information!
