My AG setup is currently in the basement, and, well, there be spiders. Me no likey spiders, so I was thinking of moving the entire setup outside, where I can blast nooks and crannies with a pressure washer at the slightest sign of web. (Right now I'm forced to get somewhat close to them and use my benzene torch to kill them, but because there are a few on the ceiling every now and then, sometimes I get a present in my hair

)
...anyway. Has anyone tried putting their march pump into an all-weather housing before? I know I'd need to make sure to flush out any remaining liquid after brew day to make sure things don't freeze, but otherwise would it work?
