Go to lowes or home depot and in the section where they have the water heaters and pipes for them. They have a piece that goes around the pipe. It looks like one of those oragne cones you see on the side of the road or on the wet floor in the store but its black and soft metal or the same material as roofing. You take the little cap off yur pipe and slide the whole cone down over then put some sealant where the cone meets the pipe and the cone channels the water away from the pipe.
