Do you have any idea as to whether the sump pump kept up with the drainage? I have two electric sump pumps in my house (one to kick in if/when the other fails or fails to keep up. It's in it's separate sump hole). I also plan on putting in a battery backup sump pump in case the power goes out. This thread just gave me some incentive to actually get it done. Glad you didn't have any speaker damage.

Don't die with a clean shop!
