Tub drain pipe broke in half! Need help!

[Jamie_Andrews]

I just recently purchased a 2003 3023 and the previous owners said they never used the tub. Well I found out on our first camping trip that the water runs out from under the camper! Upon closer inspection I found the pipe broken in half under the rear of the tub close to where it goes into the tank. See photos where the red line is where the break is located and a photo of my break.

Does anyone have any suggestion? I am thinking about using glue and prayer! I know from others on here that the pipe is cemented to the top of the gray water tank and this location is not easy to get to.
