It is crucial to keep an eye on your oil tank, whether steel or plastic. Regularly inspecting your oil tank does not take long, but can save you from serious and costly issues further down the line.
Here are some easy checks you can make to spot potential problems:
• Check the tank is clear from plant growth that could hide the condition of the tank
• Check the tank base or support for any signs of cracking or subsidence
• Check the tank has a working contents gauge; if this has a valve, make sure it’s closed
• Check all visible pipework, valves and filters for damage and signs of leaks, such as dampness or staining, especially around joints
• Check vegetation around the tank for signs of die-back (which might suggest a leak)
• Check secondary containment (tank bunds) for liquid or rubbish
• For plastic tanks, also check for cracks or splits in the plastic, or bulging/deformation of the tank profile. A plastic oil tank cannot be repaired; if it’s starting to show signs that it’s deteriorating, you are likely to need a replacement tank.
Carrying out these simple checks on a regular basis will help you to avoid potentially expensive and environmentally damaging oil leaks. In addition, fuel delivery drivers have a duty of care to check your oil tank is safe before filling. Should the driver doubt the integrity of the tank, they can refuse to fill it. Your oil boiler service engineer should also check the tank and supply pipe when carrying out an annual boiler service.
