toilet fill tube 29 extends from the toilet fill valve outlet 27 with its other end fed into the flexible tubing inlet end 35 as shown the float 41 is applying an upwards pressure on the fill valve lever 19 keeping it in an off position so that water is neither entering the tank 13 or the toilet via fill tube 29 when flush handle 23 is pushed upwards the flexible tubing 7 is forced downwards via extension 25 pushing downwards on float 41 so the flexible tubing 7 is substantially submersed beneath the water surface 37 so the inside of the flexible tubing 7 is substantially under and filled with water the water begins to siphon and drain out of tank 13 through the outlet fixture 1 shown in fig1 and fig4 lowering the water level 37 as the water level 37 in tank 13 drops below the upper most portion of flexible tubing 7 the inside of flexible tubing 7 remains substantially filled with water because of the siphon created when the flexible tubing 7 is substantially submersed beneath the water surface 37 so the water continues to drain out of the tank 13 as previously described until the water surface 37 falls beneath.
