Leak at grey tank outlet - advice wanted
There is a good dribble at the tank side of the outlet flange, it eventually fills up the corrugated plastic sheeting underneath the trailer with water. You can see some gasket material extruded out...

The black colored holding tanks are made of polyethylene. You can get solvent for that material in a can like PVC cement. Use fiberglass cloth and rebuild the area with the cloth and solvent by layering. It dries hard like the tank.
I just had to address a similar problem on my fresh water tank (although probably more serious than yours). I solicited advice on this forum and other sources. Here is what I learned:
1. My fitting was spin welded into the tank (Google it)
2. My black-colored fresh water tank is ABS, not poly. ABS cement is the appropriate product (readily available).
3. ABS cement will bond with metal window screen better than fiberglass and allow you to do some rebuilding/repair of the area.
I am not definitively judging your problem and/or materials to be the same as mine, but it sure looks similar. I just wanted to relay my experience. My fix has held for a couple weeks and a 400+ mile trip last weekend (including a pretty rough dirt road). If I can be of any assistance, feel free to ask. Good luck!
