As a homeowner in Marshfield, MA, or the surrounding South Shore towns, you rely on heating oil to keep your home warm and comfortable during our harsh winters.
While you can depend on Williams Energy for reliable heating oil delivery, it’s just as important to ensure your oil is stored safely and correctly. A well-maintained heating oil tank is crucial for protecting your home, your investment, and the environment. And we’re here for you with this as well.
This guide will walk you through the essentials of how heating oil tanks work, how to spot signs of trouble, and what you can do to prevent costly leaks and tank failure.
Heating oil tanks are built to last, providing years of dependable service. However, they don’t last forever. The most common reason for tank failure is corrosion, which quietly damages your tank from the inside out.
Corrosion typically begins with condensation. When the air inside your tank cools, moisture forms on the interior walls. This water is denser than heating oil, so it drips down and settles at the bottom of the tank. Over time, this water can corrode the steel, leading to tiny pinhole leaks.
These leaks can go unnoticed, allowing oil to seep out and potentially cause significant environmental damage and expensive clean-ups.
The best way to prevent a leak is to stay proactive. Regularly inspecting your tank is a simple yet effective step you can take. Our Williams Energy technicians also check your tank’s condition during routine maintenance visits, but knowing the warning signs yourself is your first line of defense.
Here are the key signs of potential heating oil tank failure to look for:
