Pressure Tank Fundamentals
The pressure tank is vital to a water well system. It stores pressurized water and ensures a steady supply to your home. The tank absorbs excess pressure from the pump and distributes water as needed.
What is a Pressure Tank?
A pressure tank maintains water pressure in a well system. It’s made of durable materials like steel or fiberglass. Inside, an air chamber regulates water pressure, separated by a diaphragm or bladder.
How Does a Pressure Tank Work?
The well pump draws water from the aquifer and pressurizes it. The pressure tank stores this water, releasing it as needed. As water is used, pressure drops, triggering the pump to refill the tank.
This cycle maintains consistent water pressure in your home. It prevents the pump from constantly turning on and off. This helps extend the life of your water pump.
The pressure tank acts as a buffer in your water well system. It ensures steady water pressure and reliable water distribution throughout your home.
“The pressure tank is the heart of a water well system, ensuring a consistent and reliable water supply for your home.”
Types of Pressure Tanks
Pressure tanks are vital for water well systems. They maintain consistent water pressure and extend well pump life. Let’s explore three main types: diaphragm tanks, bladder tanks, and traditional galvanized.
Diaphragm Tanks
Diaphragm tanks use a flexible rubber or butyl barrier. This separates water and air chambers, maintaining steady pressure. However, these tanks may need occasional maintenance.
Issues can include diaphragm detachment and false pressure readings. Regular adjustments help keep them working properly.
Bladder Tanks
Bladder tanks use a balloon-like membrane to hold air. This creates a barrier between water and air chambers. These tanks offer several benefits.
Their bladders last longer than diaphragms. They maintain pressure regardless of water level. Also, they resist corrosion better.
Traditional Galvanized Tanks
Traditional galvanized tanks are the oldest type. They have a steel shell with a rubber diaphragm or air control system. These tanks are reliable but can develop issues.
Problems may include rapid pump cycling and pressure issues. Regular maintenance is crucial. Replacement might be needed as they age.
Choose a tank based on water usage, budget, and space. Each type has unique pros and cons. Consult a professional for the best choice.

Choosing the Right Pressure Tank
The right pressure tank is vital for your water well system. It ensures reliable water pressure and extends equipment life. Consider your water usage, pump capacity, and installation space when choosing.
Calculate your household’s typical water usage first. Pressure tanks hold only a third of water. The rest is air, compressed to create pressure.
A 20-gallon tank provides 6 gallons of drawdown. An 85-gallon tank offers 25 gallons of drawdown capacity.
Consider your well pump’s capacity and flow rate. Larger tanks have fewer pump cycles, potentially increasing lifespan. Minimum runtime for desired drawdown varies based on flow rate.
0-10 GPM flow rate needs 1.0 GPM run time. 10-20 GPM requires 1.5 GPM run time. 20+ GPM necessitates 2.0 GPM run time.
| Pressure Tank Size | Drawdown Capacity | Pressure Switch Settings |
|---|---|---|
| 20 gallons | 6 gallons | 20/40, 30/50, 40/60 |
| 30 gallons | 9 gallons | 20/40, 30/50, 40/60 |
| 50 gallons | 15 gallons | 20/40, 30/50, 40/60 |
| 85 gallons | 25 gallons | 20/40, 30/50, 40/60 |
| 120 gallons | 36 gallons | 20/40, 30/50, 40/60 |
Lastly, measure the space where you’ll install the tank. Larger tanks need more room. A well technician can help you choose the best tank size and type.
Selecting the right pressure tank improves your water well system’s performance. It ensures optimal function and longevity. Consider all factors for the best choice.
Benefits of Using Pressure Tanks
Quality pressure tanks offer numerous advantages for water well systems. They maintain consistent water pressure and reduce pump cycling. These tanks also protect against water hammer, extending your water pump’s lifespan.
Pressure tanks ensure steady water pressure throughout your home. They store pressurized water, smoothing out demand fluctuations. This ensures reliable supply, even during peak usage times.
These tanks also reduce pump cycling. They meet short-term water demands without constant pump activation. This extends the pump’s lifespan by reducing wear and tear on components.
- Protects against water hammer, a potentially damaging pressure surge that can occur when water flow is suddenly stopped or changes direction.
- Improves water quality by allowing sediment and other contaminants to settle in the tank, rather than being circulated throughout the plumbing system.
- Provides an emergency backup supply of pressurized water in the event of a power outage or pump failure, ensuring you still have access to water for essential household needs.
A well-sized pressure tank offers many benefits. It provides consistent water pressure and protects against water hammer. The tank also improves water quality and serves as an emergency backup.
Pressure Tank Sizing and Installation
Selecting the right pressure tank size is vital for your water system’s performance. Professional installation ensures optimal efficiency. The process involves calculating tank size based on flow rate and pressure switch settings.
Calculating the Right Tank Size
Consider your home’s water usage and well pump capacity when sizing a pressure tank. A 6-gallon per minute pump often suits single-family homes. However, larger families or homes with multiple bathrooms may need more.
Pressure switch settings affect tank size calculations. Most homes use a 30/50 psi pressure switch. This means the pump activates at 30 psi and stops at 50 psi.
| Tank Size | Drawdown Capacity |
|---|---|
| 20-gallon tank | 6 gallons |
| 30-gallon tank | 9 gallons |
| 50-gallon tank | 14 gallons |
| 85-gallon tank | 25 gallons |
| 120-gallon tank | 36 gallons |
Professional Installation Tips
Have a qualified professional install your pressure tank for best results. They’ll ensure proper integration with your well pump and plumbing system. The technician will install necessary accessories like pressure switches, gauges, and safety components.
During installation, the technician will set appropriate pressure switch settings. These typically range from 20/40 to 40/60 psi, based on your specific needs.
“Proper pressure tank sizing and professional installation are essential for the long-term performance and efficiency of your water system.”
Pressure Tank Maintenance and Troubleshooting
Regular checks and fixes keep your pressure tank working well. Inspect it often, adjust air pressure, and fix issues quickly. This helps your tank last longer and prevents costly water system problems.
Inspecting the Pressure Tank
Look at your tank for signs of wear, rust, or damage. Check for cracks, dents, or other issues that could harm the tank. Gently shake it to hear if water sloshes inside.

Water Pump and Switch Integration
Pressure tanks are crucial in water well systems. They work with pressure switches to monitor and regulate system pressure. Pressure switches control the well pump, ensuring consistent water supply and optimal performance.
How Pressure Switches Work
Pressure switches sense the pressure inside the tank. They activate the well pump when pressure drops below 40-60 PSI. The switch turns off the pump when the tank reaches 50-60 PSI.
This on-off cycle is called the pump’s runtime. Proper integration of switch and pump is vital. It maintains reliable water supply and prevents issues like short-cycling.
Drawdown and Runtime Calculations
Calculating drawdown and minimum pump runtime is essential. Drawdown is the usable water volume in the tank. It’s the difference between full capacity and water volume at minimum pressure.
These calculations help prevent low water pressure. They also stop the well pump from running too often. Understanding these factors helps select the right tank size.
“Proper integration of the pressure switch and well pump is crucial for maintaining a reliable water supply and preventing issues like short-cycling or waterlogging.”
