Possible Black water tank leak

[sjaeger]

Has anyone experienced a leak with their black water tank? It looks like I have a tiny pin hole in mine causing a dripping leak underneath.... Ugh. I don't know where to start

If you have physically located the exact spot where it is leaking, and it is a black tank meaning is is made of ABS plastic, you can repair this with Plasti-Mend. I had a crack that developed in my grey tank, and I was able to make a permanent repair. I did add supports under both the tanks to prevent flexing so cracking would not happen again. http://plasti-mend.com/cart/index.php?route=product/category&path=59

Thank YOU!! I assume this can be done from the outside of the tank?

Repairs to ABS tanks are all done to the exterior surface.

The Plasti-mend kit is used on the outside of the tank (as stated by Chuckster). If the only leak is, as you say, "A tiny pin hole" and you have identified the pin hole and have access to it. You might find that using a soldering pencil or a wood burning tool and simply "smoothing over the pin hole (much like plastic welding) would be much simpler, cheaper and less "involved".

Just a thought, maybe your description of a "pin hole" is different than mine, but I wanted to at least make the suggestion.

My leaking tank turned into being a crack about 6 inches long. The repair is shown on my post at this link. http://www.keystoneforums.com/forums/showthread.php?t=29034&highlight=tank+leak+repair
