Heating oil leak problems due to pressurized oil storage tank fill procedures
In the mind of the installer, "What the hey, after all, the tank is just going to be at atmospheric pressure and filled by gravity from above, right?"
Wrong. Oil companies recognize that the time needed to complete an oil delivery is part of their profit or loss picture. Modern oil delivery trucks are designed to pump heating oil into the tank under pressure in order to speed the delivery process.
In fact most modern oil tank filler caps have a special fitting, often different from one oil company to the next, that permits the installer to "lock" the filler hose to the filler pipe during the fill-up procedure.
Usually an oil storage tank is filled right to its top during an oil delivery. This is because the way that the delivery driver knows that the tank is full is that s/he is (supposed to be) listening at the filler pipe. Tank fill or vent valves are (supposed to be) equipped with a whistling noisemaking device that indicates when the tank is full as the heating oil reaches the sounding device.
So if the pumper is not listening, say s/he went aside to smoke a cigarette or make a cell call, or if the tank top fittings are not absolutely tight, it is common to see some leakage around the tank top after a fill-up. We discuss details of oil tank pressures created during the oil tank filling operation at Oil Tank Pressures.
When and what should you do something about a leak at the top fittings of an oil tank?
