Leaf Eater Ultra Downspout Filter with Dual Stage Leaf Shedding Design, Suits 3" & 4" Pipes

I bought this to use on my gutter just before my first flush diverter as a way to clean out leaves and debris from my roof, which has asphalt shingles. I have a 330 gallon IBC tote as my rain barrel and, after installing this and the first flush diverter system, I filled the tank after only about an inch of rain. I climbed up to inspect the screen and grating and noted that it had captured a small amount of sediment and leaves, which quickly washed away during the next rainfall, just as designed. I bought this model to use on my 3"x4" rectangular gutter system, and installed 4" PVC pipe downstream from this leaf guard. This thing is great and I couldn't recommend it more!

easy to install and works great
