If you have had this rig for that long, have you ever pulled a second drain valve for the galley tank? On a lot of these rigs, there is a separate valve pull handle attached to the frame in front of or behind the axles that drains the galley tank. You have to reach it from below the J-wrap and may be hard to locate.
