I need to move a modern push-button air operated cistern which is situated on the opposite side of the wall to the pan from low level to high level in order to fit a washing machine in it's place. I would really like to know if it would be possible to get hold of a much longer air pipe for the flusher so it could reach it at high level without the wall-mounted button having to be moved from where it is, and would it work this way??
