What can be a long-term effect of not addressing water contamination in heating oil?

Water contamination in heating oil can lead to the corrosion of tank components, which is a significant long-term effect. When water mixes with heating oil, it creates an environment conducive to the growth of bacteria and microbial colonies. These microorganisms produce acids as by-products of their metabolism, and these acids can corrode metal surfaces and cause pitting. Additionally, water itself can lead to rusting of steel components, further compromising the integrity of the tank and other system components. Over time, this deterioration can lead to leaks, requiring costly repairs or even complete replacement of the tank.

Addressing water contamination early is crucial to prevent these corrosive effects, ensuring the longevity and stability of the heating oil system.
