Sump Pumps/Battery Back-Up Pumps

The most common water pump. Sump pumps are automatic pumps used to remove ground water from sump pits and transfer basement drainage to prevent residential flooding.

Battery Back-Up Sump Pumps are added in addition to your primary sump, and are powered off a 12 Volt battery. This completes your sump pump system and provides additional protection to remove ground water during a power outage, primary pump failure or heavy rain.
