APT® AST Piping Transition Sump

Key Features

• Transition sumps help meet environmental regulations by isolating metal piping from the soil.
• Transition sumps can be installed either inside or outside containment dikes.
• H-20 load rating. Pipe entries installed in lids negate the load rating.
• 30" burial depth allows the transition sump to be used as the system low point leak detection.
• Flexible entry boot provides a fuel tight and watertight seal around the metal piping and flexible piping.
