10 Clear Signs You May Have an Underground Oil Tank on Your Property
Why
Knowing the Signs of an Underground Oil Tank Matters
Underground
oil tanks can cause serious issues if left undetected:
–
Environmental contamination
– Property value
loss
– Failed
home inspections
–
Compromised soil quality
– High
removal or remediation expenses
Being aware
of the warning signs can help you avoid costly surprises—especially during a
home sale or property renovation.
1. Old or
Disconnected Oil Lines — Primary Sign of an Underground Oil Tank
If you find
copper pipes or steel oil lines running along your basement wall or foundation
and they look unused, they may be connected to a buried tank. These lines often
lead outdoors where the tank was once used for heating oil storage.
2. A
Metal Fill Pipe Outside Your Home
A fill pipe
is one of the most obvious signs of a buried oil tank. These pipes usually
stick out of the ground a few inches and were used by oil delivery trucks.
Common
locations include:
– Side of
the house
– Near
bushes
– Close to
driveways or walkways
– Along
exterior walls
If the pipe
looks capped or unused, it may be connected to an underground tank.
3. Vent
Pipes Near the Foundation — Secondary Underground Oil Tank Indicator
Older oil
tanks required venting to release pressure. A small vertical pipe with holes or
a mushroom-shaped cap is a common clue. These pipes typically appear:
– Along the
foundation
– Behind
shrubs
– Near old
fill pipes
If you find
a vent pipe with no known purpose, it may indicate a hidden tank underground.
