I had a leak around where one of the pipes connect into my fresh water tank. The cement/glue they used to affix the pipe into the side of the tank had cracked. So I re-glued it, and put some silicone around it after that dried, just for good measure. I used lots of both (was a messy looking repair, but who cares right?)
So if that's what happened with you, you know what to do.
