A flooded basement can cause you a substantial loss. A standard protection against this hazard is a sump system, designed to collect whatever water infiltrates your foundation and pump it away from your house (typically out to a discharge point somewhere in your yard). At the heart of the system is an electric sump pump located in a small pit at the lowest point in the basement.

Sump pumps wear out over time, and they need to be replaced every dozen years or so (ideally before a flooded basement tells you that your system isn’t working). Home centers and hardware stores stock a variety of models, and some basic information will help you understand their different features: Be sure not to confuse the distinction between a primary pump and a secondary (or backup) system. Standard sump pump systems assume that your water problem is independent of any power outage, even though heavy rainstorms may also knock out the electricity to your house—disabling your sump pump when you might need it the most. Accordingly, you can buy sump pumps that are powered by either special batteries (think “extra heavy duty car battery”) or even the water pressure in your home’s
standard water lines. However, these systems are light duty and are intended only for brief emergency use when your regular sump pump fails to operate. Still, if you want greater protection against the risk of flood damage, they are worth considering as a supplement to the primary sump pump that you are replacing.
