Small hole in gutter. not easy to get to. Looks like Butynol. there is a spouting pipe that is joined to the gutter and disappears through a beam and then joins the pipes going to the water tank. the hole is right where the spouting joins the gutters. I have tried Silicone and Ados "Stop Leak". It's not leaking at present, but require a permanent solution in the long run.
