ABSTRACT:
A secondary containment system is provided for use in preventing leakage to or from an underground storage tank at a joint where a riser line connects to the tank. The system includes a secondary riser tube for surrounding the riser line and a sealing ring for providing a seal between the outer wall of the storage tank and the secondary riser tube. The sealing ring has a sleeve for sealing against the outer wall of the secondary sealing tube and a flexible bell-shaped skirt for sealing against the outer wall of the storage tank. A support bracket clamps to the outer wall of the riser line and includes three arms extending radially outward. The three arms engage the secondary riser tube to hold it into engagement with the sealing ring and thereby hold the sealing ring in sealing engagement with the tank wall by maintaining a downward force on the secondary riser tube.
