Cut the pipe so the water goes in the butt then pipe the overflow so
that goes where the water was going, probably end up costing much the
same as a diverter as you can only seem to get whole lengths of pipe,
but the fittings are not too expensive.

Hi Charlie,
Thanks. That's a good idea about using the overflow to channel excess water
to where it would have gone without the mods.

Can you calarify what you meant by "cutting the pipe so the water goes in
the butt"? Do you mean have the house's downpipe going straight into the
water butt?

I have various bits of downpupe and other fittings left over from when I
replaced all the guttering last summer.
