Check Your Oil Tank After Frost

After a spell of heavy frost, it is worth taking a proper look at your oil tank.

Cold weather can put extra stress on an outdoor tank, and older tanks are usually the first to show signs of trouble. In the video, Brian explains that strong frost can affect oil tanks badly, especially older ones, and that cracking often starts in specific weak points rather than across the whole tank at once.

Why frost is a problem for older oil tanks

An older plastic oil tank can become weaker with age. After hard frost, that weakness may begin to show. What looked fine before winter can start to give way once the plastic has been under pressure from low temperatures.
That does not mean every old tank will fail, but it does mean older tanks deserve extra attention after cold weather. The video puts particular emphasis on the fact that frost can be very hard on ageing tanks. after-winter-tank-1

Where cracks often begin

One of the most useful points in the video is that you should not just glance at the tank and assume all is well. Brian specifically says to check the corners and the top, as these are common places where cracking starts to appear. after-winter-tank-1
These areas matter because:
  • corners can hold stress over time
  • the upper section of the tank is often one of the first visible places where splitting shows
  • early cracking may be missed if you only look at the front from a distance

What to look for when checking the tank

After frost, take a careful walk around the tank and look closely at the upper edges and corners.
You are checking for:
  • fine cracks in the plastic
  • signs of stress around the top
  • marks that suggest the material is starting to split
  • changes that were not there before the cold spell
The key point from the video is simple: do not just assume the tank is fine because it is still standing. Look at the areas where cracking tends to begin. after-winter-tank-1

Do not ignore early signs

A small crack can turn into a much bigger issue if it is left too long. Once a tank starts to fail, the problem rarely improves on its own.
That is why a check after severe frost is a sensible precaution, especially if the tank is older and has already spent years exposed to Irish weather.

When to call a specialist

The advice in the video is straightforward. If you are not sure about the condition of the tank, get it looked at by someone who knows what to check. Brian says that if you are unsure, you can call and have the tank inspected properly. after-winter-tank-1
That makes sense where:
  • the tank is older
  • you can see any sign of cracking
  • the plastic looks worn or stressed
  • you want peace of mind after a hard winter

A simple post-frost check can save trouble later

Heavy frost can do more damage than people realise, especially to older oil tanks. A quick inspection of the top and corners may help spot problems early, before they turn into a leak or a full tank failure. That is the main message of the video, and it is a useful one for any homeowner with an outdoor oil tank. after-winter-tank-1
If you are unsure about the condition of your tank after winter, it is better to get it checked sooner rather than leave it and hope for the best.
