The attachment is a flexible tube (10) with a closed lower end (11). The attachment is clamped (7) to a short threaded end (5) at the lowest part of the U-bend. The tube can be squeezed to agitate the contents of the U-bend. The squeezing action will dislodge small items, hair, fluff, etc. and enable them to be flushed away. Cable or foot pedal mechanisms can be added for remote operation.
