If you can access the pipes, and can make the holes they run through bigger
that will help. If you can't make them bigger, then a lubricant appropriate
for the material will help.

Thanks to all, but to reiterate: it's not the knock that occurs when the
water is turned off. It's creaking that occurs when hot water heats up
the pipes.

Sounds like it's just something I'll have to accept.
