All gutter drains are fitted with large “V” shaped funnels that have an opening of two by six inches. The large v-shaped funnels are installed to replace the traditional (and ineffective) one inch “birdie” opening at the top of the down pipe.
The V-shaped funnel is an integral part of how gutter guards work so effectively, allowing for a very high water flow rate. This is a good thing as the faster the water drains, the more debris it carries down the pipe (which is then caught by the down pipe “catch basin” in step 3). V-shaped funnels do not clog and help keep you safe. You will have no need to climb your wobbly ladder anymore to try and clean clogged gutters.
