Customer Questions & Answers

Will leaves block the grate from letting water drain?

I have an alley drain that has a different grate on it, but leaves coming from my neighbor's down spout constantly collect and block it during storms, forcing me to go out in the rain at night multiple times to clear the grate of leaves. What prevents leaves from collecting on this grate? Or do I just need to clean my neighbor's gutters regularly (they probably won't do it even if I ask them as it's a two story house in the city and not an easy task)?
Asked by: dave
The slotting in the grate is designed to allow water to pass through while preventing leaves and other debris from getting into the drain pipe. If there isn't anything between the downspout and the grate the leaves will continue to collect on the grate. If there a way to place a straw wattle between the downspout and the grate? The wattle will allow water to pass through, but will stop leaves.

4 in. Plastic Round Black Foam Polyolefin Grate is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Good Stuff Works great but not theft proof, I continuously have to replace mines because some crook in the neighborhood keeps stealing it. This time I will use 4" cast iron, concrete and seal it in. If I ever find the culprit.
