And then it happened to us! Well the electric breaker or whatever that the sump pump was linked to decided to stop working on a rainy, snow-melty night and we had a wet basement as a result. It was an inch deep in the more sloped parts, but we were really lucky that the basement isn't finished and most of our stuff was on shelves anyway. It was just a pain to roll up and remove the carpet scraps we had down there. Wet carpet is heavy!
