Chris - thanks for this , but does plumbing them together like this mean
that you get low pressure ? Is it better to fill butt1 and overflow to butt2
etc ?

It makes no difference to the pressure, which is dependent on the
depth of water in the butt, regardless of how you link them or how
many.

You will have to cut additional holes in order to link them as I
showed. But you would have to do that anyway however you link them and
it's no problem if you have the appropriate drill.
