Understanding How Sump Pumps Work
Sump pumps are typically installed in a pit located at the lowest part of your basement or crawl space. When water enters this pit, the pump’s float switch activates, causing the pump to remove the water through a discharge pipe. This process helps keep your basement dry, preventing significant water damage during heavy rains or flooding events.
Key Features to Look For
When choosing the right sump pump, it’s essential to consider several features:
- Power and Capacity: The horsepower (HP) rating indicates the pump’s power, while the gallons per hour (GPH) rating tells you how much water it can remove in a given time.
- Construction Material: Pumps made of cast iron or high-grade thermoplastic are more durable and resistant to corrosion.
- Float Switch Design: Look for reliable float switches, such as magnetically operated designs, which minimize the risk of getting stuck.
- Noise Level: Submersible pumps tend to be quieter, making them ideal for residential areas.
- Warranty and Support: A solid warranty can save you from costly repairs down the line, so ensure the pump comes with a reliable warranty.
