Liquid flow structure including a reverse flow diverter (10) is used to produce forward and reverse flow in the syphon and, on reverse flow, reduced pressure at the needle is produced by the head N of liquid, and during reverse flow some liquid enters a sampling bottle (24) through the needle (22). The needle extends into a T-piece and has a lower end at or below the mid line of the lateral leg of the T.
