Components of a Well Pump System
A well pump system consists of several key components that work together to extract water from a well and deliver it to your home. Understanding these components is essential for maintaining and troubleshooting your well pump system.
Pump
The pump itself is the heart of the well pump system. There are two main types of pumps used in well systems: submersible pumps and centrifugal pumps. Submersible pumps are installed deep inside the well and are designed to be submerged in water. Centrifugal pumps, on the other hand, are located outside the well and use suction to draw water up from the well.
Pressure Tank
The pressure tank is a crucial component of the well pump system as it helps maintain a steady flow of water to your home. It is responsible for storing the water pumped from the well and maintaining pressure in the system. When the pressure drops below a certain level, the pressure tank triggers the pump to start, ensuring a continuous supply of water.
