How Does a Submersible Sump Pump Work?


A submersible sump pump is an essential device used to prevent flooding in basements and other low-lying areas. Understanding how this equipment operates can help homeowners protect their properties from water damage. This article will delve into the workings of a submersible sump pump and its components, as well as considerations for use and maintenance.


Basic Function


The primary purpose of a submersible sump pump is to remove excess water from a sump pit, which is typically located in the basement of a home or a designated drainage area. When water accumulates in the pit, the pump activates and begins to pump out the water, preventing it from rising to levels that could lead to flooding.


Components of a Submersible Sump Pump


1. Pump Motor The pump is powered by an electric motor that is hermetically sealed to prevent water damage. The motor operates when water in the pit reaches a certain level.


2. Impeller This is the key component that moves the water. When the motor runs, it spins the impeller, creating a centrifugal force that pushes water upwards through the discharge pipe.


3. Discharge Pipe The water is expelled from the pump through this pipe, which directs the water away from the foundation of the house. Proper installation of the discharge pipe is crucial to ensure that the reclaimed water is channeled far enough away from the home to avoid re-entering the sump pit.

4. Float Switch Most submersible pumps are equipped with a float switch, which acts like a buoy. As the water level rises, the float rises with it, eventually triggering the pump to turn on once a predetermined level is reached. When the water level falls, the float switch returns to its original position, turning off the pump.


Operation Process


The operation of a submersible sump pump is relatively straightforward. When water fills the sump pit, the float switch detects the rise and activates the pump. The motor kicks in, and the impeller starts spinning, drawing water into the pump. The centrifugal force created by the impeller pushes the water through the discharge pipe, sending it away from the house. This process continues until the water level drops below the float switch’s preset level, at which point the pump automatically shuts off.


Benefits of Submersible Sump Pumps


One of the main advantages of submersible sump pumps is their efficiency. Being submerged in water, they can operate quietly and do not require priming to begin pumping. Additionally, these pumps are usually more robust against debris and sediment compared to other types of pumps, as they are designed to handle liquids mixed with solids.


Maintenance Tips


To ensure your submersible sump pump operates effectively, regular maintenance is essential. This includes cleaning the sump pit to remove debris that may clog the pump, testing the pump periodically to verify it functions correctly, and ensuring that the discharge pipe is clear and unobstructed.


In conclusion, understanding how a submersible sump pump works is vital for homeowners, particularly in flood-prone areas. By learning about the components and operation of these pumps, and by practicing regular maintenance, you can safeguard your home against the damaging effects of water intrusion.
