The other night I worked A/C 270 ( ex Ford 737 ) and noticed that on many of the ex airTran and other second hand 737's we operate, there is some sort of "bar" in the side walls of the bins. I haven't noticed this on any 737's that were delivered directly to WN. My question(s) is what is the function of this bar, and why doesn't SWA opt to have this on its 737's.

Its a cover for the fwd galley/lav grey water drain tube that ends at the fwd drain mast. Grey water drains through the tube whether its airborne or on the ground. On the aircraft without, the grey water drain tube is above the cargo compartment ceiling. Due to the lack of slope, the grey water doesn't drain through the fwd drain maston the ground. Instead there is a drain valve that opens when on the ground that diverts the grey water to the door sill drain and exits the plane just aft of the NLG wheel well.
I don't know the reasons behind one design or the other, though I personally like the idea of not having the drain/cover in the pit. Mainly due to always having to re-bend the cover retaining clips and sealing the cover with tape. At AS we have only one NG with the drain line in the ceiling, N549AS.
