You have to have an air gap e.g. cistern with ball cock valve. Or
something called a type DC pipe interrupter, but I'm not really sure
about those when attached to a bidet.

Loadsamoney, but probably in the Reliance Water Controls catalogue.

Absolute twaddle, it really is!

Maybe not if you're the neighbour whose drinking water tap is on the same
supply as your bidet/khazi.
