Understanding Well Pumps
Well pumps are the heart of a water well system. They draw water from the ground and bring it up to the surface. There are two main types of well pumps: submersible and jet pumps.
Submersible Pumps
These pumps are designed to be submerged in the water. They are efficient for deep wells and can handle various flow rates. Submersible pumps are quiet and work well for residential and commercial applications.
Jet Pumps
Jet pumps are typically installed above ground and function by creating a vacuum to draw water up from the well. They are ideal for shallow wells and are often used in residential settings.
Pressure Tanks: Ensuring Steady Water Supply
Pressure tanks are essential components that store pressurized water. They help maintain consistent water pressure in the system and reduce the wear and tear on the pump.
Sizing Pressure Tanks
A common rule of thumb for sizing a pressure tank is one gallon of drawdown for each gallon per minute (GPM) of pump capacity. For instance, if your pump delivers 20 GPM, you should have a tank with at least 20 gallons of drawdown.
Well Casing: Protecting Your Water Source
Well casing is the tubing that lines the well, ensuring that the structure remains intact and preventing contaminants from entering the water supply.
Types of Well Casing
Well casing can be made from various materials, including:
– PVC: Lightweight and resistant to corrosion.
– Steel: Durable but susceptible to rust if not coated properly.
– Fiberglass: Non-corrosive and lightweight but can be more expensive.
Well Screens: Keeping Water Clean
Well screens are used to filter out sediment and debris from groundwater. They are typically installed at the bottom of the well casing.
Custom vs. Prepack Screens
Custom-made well screens can be designed for specific filtration needs, while prepack screens are standardized options that offer ease of installation.
Check Valves: Preventing Backflow
Check valves are critical for preventing backflow, ensuring that water does not return to the well once it has been pumped to the surface.
Types of Check Valves
- Swing Check Valves: Use a swinging disc to allow flow in one direction.
- Spring Check Valves: Use a spring-loaded mechanism to close off backflow.
Pressure Switches: Automating Pump Control
Pressure switches are devices that automate the operation of the well pump based on water pressure levels. They ensure that the pump turns on and off at predetermined pressure settings.
Importance of Pressure Switches
Using a pressure switch helps maintain consistent water pressure and protects the pump from running dry, which can lead to damage.
Selecting the Right Fittings and Connectors
Fittings and connectors are vital for connecting various components of the well system. Proper selection ensures a leak-free and efficient installation.
Types of Fittings
- PVC Fittings: Lightweight and easy to install.
- Brass Fittings: Durable and resistant to corrosion.

FAQ
What is the lifespan of a typical well pump?
The lifespan of a well pump can vary, but generally, submersible pumps last around 10-15 years with proper maintenance.
How do I know if my pressure tank is sized correctly?
A pressure tank should ideally provide one gallon of drawdown for each gallon per minute of pump capacity.
Can I install a well pump myself?
While it is possible for a DIY enthusiast to install a well pump, it is advisable to consult with professionals to ensure proper installation and compliance with local regulations.
What are the signs that my well system needs repair?
Signs include fluctuating water pressure, strange noises from the pump, or sediment in the water, indicating potential issues.
How often should I replace the well screen?
Well screens should be inspected regularly, and replacement can be necessary every 10-20 years, depending on sediment buildup.
What materials are best for well casing?
PVC, steel, and fiberglass are common materials, each with different advantages. PVC is lightweight, while steel is durable, and fiberglass is non-corrosive.
How can I prevent backflow in my well system?
Installing a check valve prevents backflow by allowing water to flow in one direction only.
What factors affect the flow rate of a well pump?
Factors include the pump type, well depth, aquifer characteristics, and the size of the piping system.
Is it necessary to have a pressure switch?
Yes, a pressure switch is essential for automating the pump’s operation and maintaining consistent water pressure.
Where can I find quality water well parts?
Quality water well parts can be sourced from suppliers like www.shop-esp.com, www.thewaterguy.ca, and www.pvcfittingsonline.com, among others.
