The following indicators are things you may see at your property if you have an oil tank present:
The purpose of this pipe was to fill your underground storage tanks (UST) with oil. They are usually approximately 2-¾ inches diameter and are typically 6 to 8 feet from the original structure.
For examples, please visit our gallery and check out many different types of filler pipes.
This pipe was used to vent excess fumes from the interior of the oil tank to help prevent the risk of explosion. Additionally, this pipe also allowed airflow into the oil tank aiding in the conveyance of fuel oil into the oil burner through the feeder lines.
The vent pipe is usually attached to the house vertically and slopes to the opposite end of the oil tank than the filler pipe. The vent pipe is usually 1-¾ inches in diameter and has a open cap on the top of it.
The partially open cap on top of the vent pipe blocks water and debris from entering the tank and allows air to flow freely without interruption.
For examples, please visit our gallery and check out different types of vent pipes.
Feeder lines ( Supply Lines)
These pipes fed the fuel oil into the oil burner from the oil tank.
Feeder lines are usually made of copper and are approximately ¼ to ½ inches in diameter.
Usually an Underground Storage Tank (UST) will have 2 feeder lines and Aboveground Storage Tanks (AST) will have 1 feeder line.
The feeder lines for Underground Storage Tanks are usually buried underground, so the spotting them can be difficult.
When looking for feeder lines, the most common areas you may find them are near the furnace or foundation wall.
Many times thes pipes were removed during renovations, or when the house was converted to natural gas.
The visible signs of feeder line removal that may be present are:
Crimped lines coming out of the floor near your furnace or foundation walls.
Another sign that your feeder lines may have been removed, would be an unexplained area of replaced concrete that leads from the furnace to the foundation wall. This could indicate that someone previously dug in that area to remove the lines and replaced the concrete in that area.
For examples, please visit our gallery and check out our pictures of feeder lines.
Emergency oil burner shut off
The purpose of this switch was to cut the fuel oil supply to your oil tank to help mitigate or prevent damages in the event of an emergency.
This outlet box usually says emergency oil shut off on its face and has a toggle switch. The most common places to find this switch is in your basement, and/or near your furnace room.
For examples, please visit our gallery and check out different styles of emergency oil burner shut off.
