Hi y'all, just some words of advice, I have just dismantled my diverter
on the downcoming rainwater pipe leading to the waterbutts as we are
moving house soon, and found a lot of debri that included cherry seeds
etc, this must have stopped 50% of my rainwater collection for a couple
of years, I doubt if I would have ever looked there for problem, but it
is well worth checking along with guttering etc.
Every little helps. Mike, Cambridgeshire Dustbowl.

I simply put my rainwater downpipe directly into the water butt. Then
put an overflow on the water butt so the excess goes to... another
water butt. And the overflow water from that goes to ... another water
butt. Any after that goes down the drain. So I don't waste a drop of
rain. I'm not convinced those diverters transfer 100% of the rainwater?

No they don't, but I think for most occasions it's enough.

Collecting straight into a butt will sooner or later lead to the butt
overflowing as the pipe to the next ones won't be able to cope with the
flow.

This may or may not matter depending on where the butt is situated.
