If you’re not familiar with the latest water heater standards, you might wonder about the small tank attached to the top of many new water heaters. This is called an expansion tank, and it’s an important upgrade for safety and efficiency. So, what does it do, and do you need one in your Simpsonville home? Here’s what you should know.
How Do the Expansion Tanks Work?
Expansion tanks help absorb extra water pressure that builds up when your water heater heats and expands the water. Most city water systems have backflow prevention devices, which stop water from flowing back into the main supply. Because of this, the expanding water has nowhere to go, causing pressure to rise in your plumbing. The expansion tank gives this extra water a safe place, protecting your pipes, fixtures, and water heater from damage.
What is the Purpose of a Water Heater Expansion Tank?
The primary purpose of an expansion tank is to relieve pressure in your plumbing system. Without one, the increased pressure can cause leaks, damage to your water heater, or even bursts in your plumbing lines. The reduced pressure can also make your unit more efficient by reducing the constant strain of high pressure. By installing an expansion tank, you lengthen the lifespan of your water heater, improve system safety, and may even meet local code requirements.
Do Tankless Heaters Need an Expansion Tank or Just Traditional?
Expansion tanks are primarily recommended for traditional tank-style water heaters because these systems hold a large volume of water that expands as it’s heated. Tankless water heaters heat water on demand and do not store hot water, so they typically do not require expansion tanks. However, always check your local plumbing codes and manufacturer recommendations to be sure.
Can I add an Expansion Tank to My Existing System?
Yes, an expansion tank can usually be added to your existing water heater system. Installation is easy for a professional plumber and can help you skip costly repairs in the future. If you live in Simpsonville or the surrounding areas and wish to ensure your system is safe and up to code, the experts at Warmer Water & Plumbing can help you choose and install the right expansion tank for your setup or recommend a new tank if it makes more sense for you.
