What Should I Do If There Is Water In My Oil Tank?
Water can form in any heating oil tank. It occurs as a result of the tank warming up during the day and then cooling at night. In single skin oil tanks, it will collect in the base of the tank; in bunded oil tanks it may additionally collect between the inner and outer tanks.
Oil tanks should be inspected annually for the presence of water found to be present either inside the oil tank or in the case of bunded oil tanks, between the inner and outer tank. Failure to remove any condensation may result in fuel contamination and can cause irreparable damage.
