second post sorry i was thinking of cistern
some times caused by evaporation
sometimes it can be drawn by other toilets being used on a shared soil pipe
some times a blockage stops the water settling in the trap
or sometimes its because its a new toilet and customers are so use to seeing a larger amount of water because of the older cisterns having 9lt flushes rather than a 6lt modern flush
