Yes, that did occur to me. However, the existing hole is on the same side as
the connection to the rising main, and the shower installation instructions
say (several times) that the shower feed should be connected on the opposite
side to reduce the chance of air being drawn in. Is this really a problem?

I think that what they are saying here is that if there is a silencing
tube on the float valve it will have an air hole to prevent reverse
siphoning if the mains supply fails. If there is a fair flow of
water then you get air bubbles into the tank at the bottom of the
tube.

I would take a look with some taps running and see what it looks like.



Thanks for the holesaw advice - the last thing I need is to be making an
arse of drilling into my water cistern. I'm kind of used to diy jobs taking
4 times as long as I originally intend (since most of the stuff I do is the
first time I've tried it) but having to spend hours in the loft trying to
repair a bodge would really mess my day up...
