The problem with basements is that they are a natural catchall. Gravity seems to pull all sorts of unused and obsolete objects into basements. When this clutter is mixed with a few inches of water brought in after a heavy rain, two things happen:
- All the clutter is ruined.
- The clutter becomes much more precious than it ever was.
So, for the sake of all that clutters, and what it might fetch on eBay, consider installing a sump pump.
- This is basically a pump in in a pit in the lowest part of your basement that, if the basement starts filling with water, will turn on automatically and pump the water outside.
