In reply to Adam Moroz:
Hi,
I have one of these, how much of it snapped off, just the jug? You could attached the large bit to the wall then just screw the other bit on to the wall as I'm sure there are screw holes in the back of the jug. some of the weight will be on the screw and some of the weight will get transfered through the board if you get the fit close enough!
either that or araldite it!
