So far it's always been dry when I've received a new delivery of heating oil, but what if it's raining? Do people routinely hold an umbrella over the filler pipe?
My last but one service verified that the oil tank has absolutely no water in it (the engineer tested with some special gunk on a stick that would turn pink), so given the amount of rain we're getting and the fact that my oil level is getting near the re-order stage, should I buy that umbrella and keep the inside of the tank water-free?
