I leave my WSM outside on a patio that is not covered, and I have had a problem with water getting in it when it rains. Sometimes there will be as much as an inch of water in the bottom section after a heavy rain. (Yes, I do have the cover on the WSM!) I?m not sure if the cover is leaking or if water is somehow splashing up from below ? I do have all of the vents closed. Has anyone else had this problem? I am thinking of buying a larger cover so that the cover will protect the unit all the way to the ground. Any suggestions?
