If you have a water heater in your home, you may have heard of an expansion tank. But what exactly is an expansion tank, and what does it do? Simply put, an expansion tank is a safety device that helps regulate the pressure in your plumbing system by providing a space for the water to expand as it heats up. Without an expansion tank, the pressure in your plumbing system can increase and cause damage to your water heater, pipes, and other plumbing components.

At Wilson Plumbing, we understand the importance of having a properly functioning plumbing system in your home. That's why we offer a wide range of plumbing services, including water heater installation and repair. Our team of experienced plumbers can help you determine if your water heater needs an expansion tank and install one if necessary. By choosing Wilson Plumbing, you can rest assured that your plumbing system is in good hands.

If you're still unsure about whether or not your water heater needs an expansion tank, it's important to understand the potential risks of not having one. Without an expansion tank, the pressure in your plumbing system can increase to dangerous levels, which can cause your water heater to fail and even lead to leaks or floods in your home. Additionally, installing an expansion tank can help improve the energy efficiency of your water heater, which can save you money on your energy bills over time.

Understanding Expansion Tanks

Expansion tanks are an essential component of a water heater. They are designed to relieve pressure buildup caused by thermal expansion. In this section, we will discuss the purpose of an expansion tank, how expansion tanks work, and the different types of expansion tanks available.

Purpose of an Expansion Tank

The purpose of an expansion tank is to protect your plumbing system and water heater from damage caused by thermal expansion. When water is heated, it expands, and if there is no room for expansion, the pressure inside the system increases. In a closed system, this pressure can cause damage to your plumbing system, leading to leaks, burst pipes, and other plumbing problems. An expansion tank provides a space for the expanded water to go, reducing the pressure inside the system.

How Expansion Tanks Work

Expansion tanks work by using a diaphragm or bladder to separate the air and water inside the tank. As the water in the system expands, it enters the expansion tank, compressing the air or bladder inside. This compression allows the water to expand without increasing the pressure inside the system.

Types of Expansion Tanks

There are two main types of expansion tanks: diaphragm and bladder. Diaphragm expansion tanks have a rubber diaphragm that separates the water and air inside the tank. Bladder expansion tanks have a flexible bladder that separates the water and air. Both types of expansion tanks work in the same way and are equally effective at reducing pressure buildup caused by thermal expansion.

That's why we offer a wide range of plumbing services, including installation, repair, and maintenance of water heaters and expansion tanks.

Installation and Placement

Where to Install an Expansion Tank

When it comes to installing an expansion tank, there are a few things to consider. First, the expansion tank should be installed on the cold water supply line to the water heater. This is typically done by connecting the expansion tank to a tee fitting that is installed above the water heater's shut-off valve. The tee fitting should be installed at least 6 inches above the water heater to allow for sufficient clearance.

It is important to note that the installation of an expansion tank is not always required. According to local building codes, an expansion tank may only be required if the water pressure in your home exceeds a certain level. It is best to consult with a licensed plumber to determine if an expansion tank is necessary for your specific situation.

Installation Process

The installation process for an expansion tank is relatively straightforward. It typically involves turning off the water supply to the water heater, draining the water from the tank, and then installing the expansion tank on the cold water supply line. The tank should be installed with the air valve facing up and should be supported by a bracket to prevent it from sagging.

It is important to ensure that the expansion tank is properly pressurized before turning the water supply back on. This can be done by using a tire pressure gauge to check the air pressure in the tank. The pressure in the tank should be set to match the water pressure in your home.

When it comes to installation and placement of an expansion tank, it is important to follow local building codes and regulations. At Wilson Plumbing, we have licensed plumbers who are knowledgeable about local building codes and can ensure that your expansion tank is installed correctly.

Maintenance and Inspection

Regular Maintenance

To ensure your water heater expansion tank functions properly, it is important to perform regular maintenance. One of the most important things to do is to check the pressure of the tank regularly. You can do this by using a tire pressure gauge and checking the air pressure in the tank. The pressure should be set to the manufacturer's recommended range, which is typically around 40 psi.

It is also important to check for any leaks around the tank or in the pipes leading to and from it. If you notice any leaks, it is important to have them repaired as soon as possible to prevent any further damage to your plumbing system.

Identifying Issues

If you notice any issues with your water heater expansion tank, it is important to address them as soon as possible. Some common issues include leaks, low pressure, and a malfunctioning pressure relief valve. If you notice any of these issues, it is important to have them repaired or replaced by a professional plumber.

When to Replace

Water heater expansion tanks have a lifespan of around 5-10 years. If your tank is older than this, it may be time to consider replacing it. Additionally, if you notice any significant issues with the tank or if it is no longer functioning properly, it is important to have it replaced.

Troubleshooting Common Problems

As with any mechanical system, water heater expansion tanks can experience problems that require troubleshooting. Here are some of the most common issues you may encounter and how to fix them.

Pressure Buildup Issues

Excess pressure buildup in the expansion tank can cause leaks, pressure fluctuations, and even damage to the tank itself. If you notice any of these issues, the first thing to check is the relief valve. If it's not functioning properly, it may need to be replaced.

Another possible cause of pressure buildup is corrosion inside the tank. Over time, minerals and sediment can accumulate and cause blockages that prevent proper water flow. If this is the case, the tank may need to be flushed or replaced.

Water Leaks and Drips

Leaking or dripping water from the expansion tank can be caused by a number of factors, including a faulty relief valve, excess pressure, or a damaged tank. If you notice any leaks or drips, it's important to address the issue immediately to prevent further damage.

One way to troubleshoot leaks is to check the Schrader valve, which is located on top of most tanks. If you press it and water comes out, the tank may be overfilled and need to be drained. If nothing comes out, the tank may be underfilled and need to be recharged with air.

Air Pressure Adjustments

The air pressure inside the expansion tank is crucial for proper functioning. If the pressure is too high or too low, it can cause a variety of problems, including leaks, pressure fluctuations, and damage to the tank.

To adjust the air pressure, you'll need to turn off the water supply to the tank and drain any excess water. Then, use a tire pressure gauge to check the air pressure inside the tank. If it's too high, you can release some air through the Schrader valve. If it's too low, you can add air through the same valve.

If you're experiencing any of these issues with your water heater expansion tank, it's important to address them as soon as possible to prevent further damage.

Cost Considerations

When considering the cost of installing an expansion tank on your water heater, it's important to factor in both the initial cost and the long-term savings. The cost of an expansion tank can vary depending on factors such as size, type, and brand. According to Angi, the average cost of a water heater expansion tank installation is $325, with most people paying between $150 and $450 for the task.

While this may seem like a significant expense, it's important to remember that an expansion tank can help prolong the life of your water heater and prevent costly repairs. Additionally, having an expansion tank installed can help you save money on your energy bills by reducing the strain on your water heater and ensuring that it operates efficiently.

It's important to note that while some homeowners may attempt to install an expansion tank themselves, it's always best to hire a licensed plumber to ensure that the installation is done correctly. This can help prevent any potential damage to your water heater and ensure that the warranty remains valid.
