Interesting Jenny. With that set up, your right hand butt would get filled last then? I wonder though if the others have more pressure, so fill up quicker? All that water pushing down, could well mean more pressure, possibly? I had been wondering if I placed the butts a distance away from our main garden area, if there'd be enough pressure to be able to water plants with a long pipe?
@paulpuk2000, the one nearest the downpipe fills first, but the speed of filling up depends on how hard it's raining onto the roof that drains into that downpipe.
Pressure at the tap I think depends only on the height of water in that butt. The levels don't equalise as I use the water, once it's below the level of the connecting pipes.

Connecting near the top is the right idea. The butts will fill in turn, you can use each one without affecting the water level in the others and a leaky tap will only empty one butt.
Leaking tap is something to consider, for sure. But as far as pressure is concerned, if you have joined the butts at the bottom, whenever you open the tap, in effect, you have all 3 butts pushing down water, to that tap, so if pressure was a consideration for you, connecting at the bottom may be well worth considering.
Thanks to everyone who contributed here. I really feel like I've joined a family. :-)
Makes no difference to pressure, that is governed by the head of water I.e. height of water surface over tap height. You could connect a thousand butts together and the pressure will be just the same as one.
I have mine connected at the bottom so the 3 butts act as 1 big butt but it makes no difference to the pressure. As steephill says you can only increase the pressure by raising the butt

Thanks guys. I thought I might be stepping on stony ground.
So, 3 butts, linked as one (linked at the bottom) means you only use one tap. This could be useful for me, as I have a narrow gap between the garage and the wendy house, which could probably fit 3 butts in, and would be nearer to the main garden, and not be unsightly, so looks like the bottom linkage, might be the one for me. (I might need to revise my physics. :-) )
