The professional team at Mountain Home Services offers complete water heater services in Northern Utah, including water heater expansion tank installation.

Expansion tanks, also known as thermal expansion tanks, are required for homes with closed water heater systems. Our expert team will ensure your expansion tank is installed correctly for optimal operation for years to come.

What Is a Thermal Expansion Tank & Why Do I Need One?

When water is heated, it expands. In a closed water heater system, where water is prevented from flowing back through the supply line, there must be a place for water to go when thermal expansion takes place. That’s the purpose of the thermal expansion tank.

If your water heater system doesn’t have an expansion tank, you risk leaks and corrosion within the system due to the high pressure caused by thermal expansion.

Protect your home’s water heater with an efficient expansion tank installation.

Thermal Expansion Tank Installation

We install thermal expansion tanks onto existing water heaters throughout Northern Utah, and surrounding areas. We’ll assess your water heater system to determine which size expansion tank you need based on your system’s capacity and water pressure.

With proper installation, you can expect your expansion tank to last five to 10 years.

Can I Install an Expansion Tank Myself?

It can be tempting to try to install an expansion tank yourself, but it’s best to let professionals like those at Mountain Home Services handle the installation. Otherwise, you risk injury as well as damage to your water heater system and home.

Our licensed plumbers are experienced in handling the installation, and we can quickly troubleshoot any unexpected problems that arise.
