The Ultimate Guide to Well Pump Bladder Tanks
Readers,
Welcome to our comprehensive guide to well pump bladder tanks. In this article, we will delve into the world of these essential components that ensure a steady water supply in homes and properties relying on well water systems. We’ll discuss their functions, benefits, types, sizing, and maintenance to help you make informed decisions about your well pump system. So, whether you’re a homeowner, a plumber, or simply curious about well pump bladder tanks, read on to discover everything you need to know.
What is a Well Pump Bladder Tank?
A well pump bladder tank is a cylindrical tank installed in well water systems. It consists of two compartments: an inner bladder and an outer tank. The inner bladder is made of a flexible material, such as rubber or polyurethane, and it contains air or gas under pressure. The outer tank is typically made of steel or plastic and holds water.
How Does a Well Pump Bladder Tank Work?
When the well pump operates, it pressurizes the water. This pressurized water enters the outer tank and compresses the inner bladder. As the water pressure increases, the inner bladder expands and stores the pressurized water. When the water is released, the bladder collapses, pushing the water out of the tank and into the plumbing system.
Benefits of Using a Well Pump Bladder Tank
- Maintains a Steady Water Pressure: Bladder tanks prevent fluctuations in water pressure, ensuring a consistent flow from faucets, showers, and appliances.
- Reduces Pump Cycling: By storing pressurized water, bladder tanks reduce the number of times the well pump needs to cycle on and off, extending its lifespan and reducing electricity consumption.
- Protects the Pump from Water Hammer: Water hammer occurs when water flow is suddenly stopped, creating a pressure surge in the pipes. Bladder tanks absorb pressure spikes, protecting the well pump from damage.
- Provides Water Storage: In the event of a power outage, a bladder tank can provide a temporary supply of water for essential use.
- Reduces Noise: Bladder tanks dampen the sound of the well pump, making it less noticeable when it operates.
Types of Well Pump Bladder Tanks
Pre-Charged Bladder Tanks:
These tanks come pre-charged with air or gas at the factory. Pre-charging eliminates the need for manual inflation upon installation.
Non-Pre-Charged Bladder Tanks:
These tanks require manual inflation to the recommended pressure using an air compressor or a hand pump.
Vertical Bladder Tanks:
Vertical tanks are tall and narrow, designed to occupy less floor space.
Horizontal Bladder Tanks:
Horizontal tanks are wider than they are tall, providing more storage capacity for smaller spaces.
Sizing a Well Pump Bladder Tank
The proper size of a well pump bladder tank depends on:
- The capacity of the well pump: The tank should be able to accommodate the maximum flow rate of the pump.
- The demand for water: Consider the number of fixtures and appliances in the home and their water usage patterns.
- The desired water pressure: A larger tank will provide more stored water and higher pressure.
Maintaining Well Pump Bladder Tanks
- Check Water Pressure: Regularly monitor the water pressure in the tank using a pressure gauge. Maintain the recommended pressure as specified by the manufacturer.
- Inspect the Bladder: Periodically remove the tank from the system and inspect the bladder for leaks or damage. Replace if necessary.
- Recharge the Bladder: For non-pre-charged tanks, recharge the bladder to the recommended pressure using an air compressor or a hand pump.
Well Pump Bladder Tank Table Breakdown
| Feature | Vertical Bladder Tank | Horizontal Bladder Tank | Pre-Charged Tank | Non-Pre-Charged Tank |
|---|---|---|---|---|
| Shape | Tall and narrow | Wide and short | Cylindrical | Cylindrical |
| Space Requirement | Less floor space | More floor space | Pre-charged | Manually inflated |
| Installation | Easier to install | May require more space | Convenient | Requires manual inflation |
| Maintenance | Less maintenance | More maintenance | Maintains pressure without inflation | Requires periodic inflation |
Conclusion
Well pump bladder tanks are crucial components of well water systems, providing a steady water supply, reducing pump cycling, protecting from water hammer, and offering temporary water storage. By understanding their functions, types, sizing, and maintenance, you can ensure optimal performance and longevity of your well pump system.

FAQ about Well Pump Bladder Tank
What is a well pump bladder tank?
A well pump bladder tank is a pressure vessel that is installed on the discharge side of a well pump. It stores water under pressure and helps to maintain a consistent water pressure in the home.
Why do I need a well pump bladder tank?
A well pump bladder tank can help to:
- Maintain a consistent water pressure in the home
- Reduce water hammer
- Extend the life of the well pump
How do I size a well pump bladder tank?
The size of the well pump bladder tank is determined by the flow rate of the well pump and the desired pressure range. A general rule of thumb is to choose a tank that is about 1/2 to 3/4 of the pump’s flow rate.
Where should I install a well pump bladder tank?
The well pump bladder tank should be installed on the discharge side of the well pump, as close to the pump as possible. It should be installed in a vertical position and should be supported by a concrete pad or other solid surface.
How do I maintain a well pump bladder tank?
The well pump bladder tank should be checked periodically for leaks and for proper air pressure. The air pressure should be checked with a tire gauge and should be maintained at the manufacturer’s recommended level.
What is water hammer?
Water hammer is a sudden, sharp increase in water pressure that can occur when a faucet is quickly closed or a valve is suddenly opened. Water hammer can damage pipes and fixtures, and it can also be a nuisance.
How does a well pump bladder tank reduce water hammer?
A well pump bladder tank acts as a cushion that absorbs the shock of water hammer. When water hammer occurs, the water in the tank is compressed and the pressure in the tank increases. This helps to reduce the pressure surge that can damage pipes and fixtures.
How do I extend the life of my well pump?
A well pump bladder tank can help to extend the life of the well pump by reducing water hammer and providing a more consistent water pressure. This can help to reduce wear and tear on the pump and extend its life.
How much does a well pump bladder tank cost?
The cost of a well pump bladder tank varies depending on the size and type of tank. A typical tank will cost between $50 and $200.
How long does a well pump bladder tank last?
A well pump bladder tank typically lasts for 5 to 10 years.
