• The Tank: The outer shell of the pressure tank, typically made from corrosion-resistant materials, is designed to withstand high pressure and protect the internal components.
• The Diaphragm or Bladder: This flexible membrane divides the tank into two chambers—one for water and the other for air. It helps maintain pressure by allowing the air to compress as water fills the tank.
• The Air Valve: Located at the top of the tank, the air valve is used to inflate or deflate the air chamber to maintain the correct pressure level.
• The Inlet and Outlet Ports: These ports connect the tank to the well and the distribution system, allowing water to flow in and out as needed.
• The Pressure Gauge: This instrument provides real-time information about the pressure within the tank, helping users monitor the system’s performance.

Role of a Pressure Switch in a Water Well System

The pressure switch is an integral part of the water well system, controlling the operation of the pump and maintaining the desired water pressure in the tank. It is essentially an automated device that monitors the pressure levels and activates or deactivates the pump accordingly. When the water level in the tank drops below a certain threshold, the pressure switch senses the decrease in pressure and signals the pump to turn on, allowing water to refill the tank.

Conversely, when the tank is filled to its capacity, the pressure switch detects the increased pressure and turns the pump off. This cyclical operation prevents the pump from running dry and ensures that water is available when needed.

The pressure switch is crucial for maintaining efficient pump operation and preventing unnecessary wear and tear on the system.

By efficiently managing the pressure levels, the pressure switch helps provide a steady supply of water, ensuring that the system operates smoothly and reliably.

How Water Well Pressure Tanks Function
