A liquid draining structure can pass a liquid from a first side of a barrier to a second side of the barrier. The liquid draining structure can include a liquid conductor, including an entry end located at the barrier first side and a discharge end located at the barrier second side. The liquid conductor can define a passageway that extends through the liquid conductor. The liquid draining structure also can include a securing member releasably attachable to the liquid conductor at any one of a plurality of positions. The securing member can engage the barrier, preventing the movement of the liquid conductor. The securing member can be attached to the second side of the barrier. The liquid draining structure can include a flange secured at the entry end of the liquid conductor and engaging the first side of the barrier, preventing the movement of the liquid conductor.
