The Galley Tank Dilemma - 2006 3670RL

[EllsworthToohey]

Here is my latest maddening event. I have a slow drip leak from the Galley tank below the Kitchen Sink. Its not a major leak but I do not want water pooling up in the plastic under belly panels, so I decided to drop the tank for easier inspection and repair.

1st thing I did after watching several videos on tank removals, was to cut the straight down pipe into the tank above the floor to pull out to free the tank. I expected the pipe to be removable but it will not budge! This now gets critical, because:

The galley tank is held in place by frame cross members supporting it by the flange around the top. To remove the tank the rear cross member can be removed with 2 bolts at each end. Separate the exit plumbing at the gate valve. Disconnect the sensor wires and it will slide toward the rear of the trailer and then drop out after an inch or two move. Ooops! It cannot move because the drain pipe is glued into the top inlet!!!

The forward cross member is WELDED in place! Only the rear Xmember is removable. This is a monster dilemma. I cannot remove the tank because the drain pipe prevents sideways movement and the welded xmember prevents dropping vertically!!!

Has anyone ever run into this situation? Any recommendations short of just destroying the tank to get it out?

Tank has obviously been removed at some point in its life because there were a complete set of new sensors installed right next to the original ones. So this sounds like whomever reinstalled it, did not think about what they were doing when gluing the down pipe into the tank thru the kitchen floor.

Grrrrr. Help!
