This spring I installed a cover with a mesh screen that replaces the snorkel. I bought it from Jenks, but they don't seem to list it on their site now.
Anyway, I never had a rain/water problem when I removed the snorkel, but I did have a problem with small rocks, dirt, and even leaves getting sucked in there. None of that could pass the filter, but it was a pain cleaning them out of the filter. The mesh screen cured that.
