A temp fix, if it's in the middle of a straight piece. They make a rubber and metal sleeve. They come in different lengths and diameter. It has a rubber inside with hose clamps on the outside. Put it over the pipe. Pick the pipe up and slide it to the middle of the broken pipe. Tighten down the clamps. There is a name for it, but I cant remember what it is. Plumbers use them when connecting two pipes together, if they can't get a collar in.the line under the camper around the area of the sewer and septic lines this camper has both. its all black pvc it looks like where the pipe is supposed to be connected its not. i poured water into the sink and it came out the open area.
