Does an expansion tank cure water hammer? the ultimate guide to unlocking the truth.

Water hammer is a common plumbing issue that occurs when a faucet or valve is quickly closed, causing a sudden surge of pressure in the pipes. This can lead to a variety of problems, including:

• Leaky faucets
• Burst pipes
• Damage to appliances

An expansion tank is a device that can help to mitigate water hammer by providing a cushion of air that absorbs the pressure surge. But does an expansion tank always help with water hammer?

How Does an Expansion Tank Work?

An expansion tank is a closed vessel that is connected to the plumbing system. It contains a diaphragm or bladder that separates the water from the air. When the water pressure in the system increases, the diaphragm expands, compressing the air in the tank. This creates a cushion of air that helps to absorb the pressure surge.

Does an Expansion Tank Always Help with Water Hammer?

An expansion tank can be a very effective way to reduce water hammer. However, it is important to note that an expansion tank will not always completely eliminate water hammer. This is because there are other factors that can contribute to water hammer, such as:

• The length of the pipes
• The size of the pipes
• The number of fixtures in the system

If you have a severe water hammer problem, you may need to take additional steps to reduce the pressure surge. These steps may include:

• Installing a water hammer arrestor
• Replacing the pipes with larger ones
• Reducing the number of fixtures in the system

Benefits of an Expansion Tank

In addition to reducing water hammer, an expansion tank can also provide a number of other benefits, including:

• Protecting your plumbing system: An expansion tank can help to protect your plumbing system from damage caused by water hammer.
• Extending the life of your appliances: Water hammer can damage appliances such as dishwashers and washing machines. An expansion tank can help to extend the life of these appliances by reducing the amount of stress they are exposed to.
• Reducing noise: Water hammer can cause a loud banging noise when it occurs. An expansion tank can help to reduce this noise by absorbing the pressure surge.

How to Choose an Expansion Tank

If you are considering installing an expansion tank, it is important to choose the right size tank for your system. The size of the tank will depend on the following factors:

• The size of your plumbing system
• The number of fixtures in the system
• The severity of the water hammer problem

It is important to consult with a qualified plumber to help you choose the right size tank for your system.

How to Install an Expansion Tank

Installing an expansion tank is a relatively simple process. However, it is important to follow the manufacturer’s instructions carefully. The following steps provide a general overview of the installation process:

1. Shut off the water supply to the plumbing system.
2. Drain the water from the plumbing system.
3. Install the expansion tank according to the manufacturer’s instructions.
4. Turn on the water supply to the plumbing system.
5. Check for leaks.
