Mounting sky on top of a flag pole

I mounted my sky on top of my telescoping flag pole using 22mm id silicone hose. I left a 1 inch gap between the metal spacers that are inside the silicone hose. I am getting a false rain what seems to be between 1 and 2.25 inches. My problem is the house next to me on the south side is about 15 foot higher than my house so the flag pole would have been perfect. Any ideas?
