Have you ever glanced at your oil tank and thought “I wonder when that thing needs replacing?”. You’re not alone - questions about heating oil tanks are common amongst homeowners. And because heating oil tanks typically deteriorate from the inside out, it’s important to be able to spot the signs and replace it before it becomes a problem.
Oil tanks typically last between 15-25 years, depending on maintenance and general upkeep. It’s important to hire a professional if you believe your tank needs replacing or is of retirement age. But, there are still a few things you can look out for to make sure everything’s a-ok.
What to look out for
Tank Location - If you’re tank is located outside and exposed to the elements, ice and snow can make their way into lines and cause damage.
Dents - Dents are indication of a faulty operating tank and should be inspected.
Rust and Wet Spots - Corrosion and wet spots and indications of a tank exposed to moisture, which might be a leading indicator of internal problems.
Uneven Legs - If the tank was installed incorrectly and is not level, it could shorten the lifespan of your tank.
Broken Fuel Gauge - A broken fuel gauge or oil surrounding the fuel gauge are signs of potential internal damage
Oil on the ground - Most oil tank failures start as pinholes. If you notice oil on ground, call a professional immediately.
As mentioned, most oil tank issues start on the inside and work their way out. Over years of use, heavy sediments and moisture can build up on the inside of the tank. If your tank level is low, these sediments can get into oil lines and clog things up. If your tank is older than 25 years old, you should consider replacing for preventative measures.
If your tank is located outside, you should give it extra attention in the winter months. After a snowfall, remove snow and ice from the tank. If you’re feeling energized, clear a pathway to the tank so your oil delivery driver can reach your tank safely.
