In this video, our Roto-Rooter expert will explain how a sump pump works and why it's important to test your sump pump regularly. You'll learn about the benefits of having a battery backup system, or Venturi water-powered pump. When the groundwater level underneath your basement rises during periods of rain or thawing, it can pose a threat of flooding in low-lying areas. When the pit begins to fill, the float of the sump pump turns the pump on, keeping the water level underneath your house from rising too much. Your local Roto-Rooter plumber can help if you need a new system or simply want to learn more about a battery backup system for your current pump. Our Roto-Rooter plumbers can ensure your sump pump still works in the event of a power outage to increase flood prevention.
