Abstract:
A rain draining apparatus for a sliding window assembly of a building mounted within a window opening and having a track and windows slidably retained within the track includes a drain conduit having a linking segment extending from and in fluid communication with a window track inside a building, and having an upright segment extending from and in fluid communication with the linking segment and extending below the window track and opening outside the building, the upright segment being in fluid communication with a check valve; and a pressure equalizing vent structure for equalizing air pressure throughout the drain conduit extending from and opening within the building into the drain conduit upright segment; so that water in the track flows into the upright segment and accumulates as a column above the check valve and then drains through the check valve when the column reaches a sufficient weight to overcome the opposing force of outside air pressure.
