How could water get into your oil tank?

Extremely wet or hot weather can cause water problems for your oil tank, since rain and condensation can both lead to water contamination in your oil. Some of the most common reasons for water contamination include damage to your tank such as little cracks or not being careful to fasten the cap on properly. This can allow water to get into your tank and add moisture into the air which then causes condensation.

Why is having water in your oil tank a problem?

Water can hurt your oil tank or boiler without you realizing it until it is severely damaged. Knowing your oil tank has been contaminated by water is difficult to recognize, as it sinks to the bottom of the oil. To make sure you don’t experience this unpleasant surprise, we at are going to share some tips on how to prevent water contamination from occurring in your oil tank.

Tips on how to prevent water contamination in your oil tank:

  2. Check your tank and pipes for evidence of age and use such as cracks, corrosion, oil stains, or any other damage.
  3. Check around your tank for any signs of leaks.
  4. Check your tank walls. If they are bulging, it may indicate that they’ve been weakened, which could mean a new tank is needed.
  5. If you have a bunded tank (a tank with a secondary wall), check to make sure that leaves and/or water are not clogging the wall.
  6. Check your tank’s lid to be sure that it is secure. It should be level and not loose.
  7. Make sure there are no overgrown plants near or over the top of your tank, since they may drip water into the tank after it has rained. Put some water removal sponges at the bottom of the tank to reduce condensation.
