I want to reduce our metered mains water usage. So I'm
considering using rain water collected from the roof via a
huge water butt outside for flushing the downstairs toilet.
I've heard of others that have done this. I just wondered
what issues I need to think about?

I don't know what French regs are but the Green Building Store sells
specially designed rainwater/mains water WCs which are very efficient and
switch automatically between the two water sources.

They are expensive though ...

I had a browse through their site but couldn't find the
auto switching toilets. It defeats the object if they are
expensive though. I don't want to spend vastly more than
could possibly be recouped through using less mains water.

The downstairs loo just struck me as a fairly obvious, easy
and cheap target for replacement with rain water, since the
butt would be outside very near for connection.
