Thank you for the replies. The friction loss chart was very interesting;
I'm not sure I totally understand it, but I get the general gist. To be
honest, this is exactly what I expected to hear but what I most dreaded.
There is no easy way to run a new pipe to the waterfall. Even the easiest
route means excavating about 20 feet of rockery that has been in place
about 25 years and a pathway that crosses the rockery.

What they said...

I'd add that anybody who told you that you should use a smaller pipe
to "create more force" needs to be reported to your local Better Business
Bureau. They shouldn't be in this business, as they clearly don't have a
clue.

Now, as to fixing the problem - might it be possible to run the pipe
_inside_ the pond and right up the face of the waterfall? The morons who
built my waterfall (and _also_ shouldn't have been in the business) should
have done that, instead of making two holes in the liner to go outside the
pond and then back in, and increasing the total length of pipe.
