A siphon tube for maintaining a trickle flow of fluid through a toilet tank reservoir and a toilet bowl. A water supply line is in fluid communication with the tank by virtue of a ball cock valve, the tank reservoir fluidly interconnects with the bowl by an overflow tube. The siphon tube includes an elongated and interiorly hollowed body having first and second fluidly interconnecting and parallel extending lengths, the first length being shorter than the second length. An upper interconnecting end is established between the fluid lengths and further includes a plurality of winding coils. Upon prefilling the siphon tube with a volume of fluid, the second extending length is inserted into the overflow tube, causing a trickle flow of fluid to be drawn from the tank reservoir, by vacuum pressure, into the first length, across the winding coils, and out the second length into the bowl, the ball cock valve occasionally activating to draw fluid from the supply line into the tank reservoir.
