Water Ingress Prevention
In addition to preventing tank uplifting during
floods, the following steps should be taken in
flood zone 4 to resist water from entering the tank
through the top openings and piping
• Vent Openings - Extended the vent pipe at
least 24" above the tank top and secure a vent
cap to the vent pipe top.
Do not plug vent openings!
• Fill Openings – Install a leak proof fill pipe cap
(such as Beckett 13100G or Philfair 93-2), or extend
the fill pipe at least 24" above the tank top.
• Gauge and Other Openings - Ensure liquid
level gauges are leak proof, and seal all unused
tank top openings with threaded steel plugs.
• Sealing Compounds – Use water/oil resistant
pipe sealing compounds, on all threaded connections.
BEFORE FLOOD EVENTS
Recommended steps that should be taken to reduce
the risk of tank damage and spills before an expected
flood event include:
• Inspection of the tank, supports and flood
resistance method used to ensure they are not
corroded or otherwise damaged, and all connections
are tight.
• Inspection of the tank piping and other tank
openings to ensure they are leak-tight.
• Ensure the bottom outlet is fitted with a shut-off
valve before connecting to other component
• Shut off the oil supply valve(s) at the tank and
burner prior to leaving the property.
AFTER FLOOD EVENTS
Recommended steps that should be taken prior to
returning the tank to service after a flood event has
occurred include:
• Inspection of the tank, supports, foundation, piping,
lines and other tank components for damage,
and if found make appropriate repairs.
• Inspection of the tank for any entry of water,
with water finding paste, and if found, contact a
licensed contractor.
• If any fuel oil has spilled on your property from
your tank or another tank, contact the appropriate
authorities.
