A ducted flexible entry boot assembly provides a fluid-tight fitting between a wall of a fluid containment region and a conduit passing through the wall. The ducted flexible entry boot assembly comprises a seal member adapted to be disposed within the containment region, the seal member having a substantially planar seal portion and an integral hollow support sleeve concentric with the seal portion and adapted to extend axially into the containment region. The support sleeve has an outer surface and an inner, conduit receiving surface, and has a degree of flexibility relative to the seal portion sufficient to allow for the insertion of the conduit at angles equal to or other than an angle normal to the fluid containment wall while maintaining a fluid-tight environment. A mechanism is provided for rigidifying the seal portion of the seal member. The hollow support sleeve is releasably attached to the conduit. A flexible, corrosion resistant sealing ring member is adapted to be disposed outside the containment region. A flexibly rigid ducting boot is integrally formed with, and extends outwardly from the sealing ring member. A mechanism is provided for sealing the sealing ring member to the wall. The seal member is releasably attached to the wall of the containment region.

An outer seal member is disposed outside of the containment region, the outer seal member having a substantially planar seal portion and an integral second hollow support sleeve concentric with the seal portion and extending axially away from the containment region. A mechanism is provided for rigidifying the seal portion of the outer seal member. The first and second support sleeves have a degree of flexibility sufficient to allow for the insertion of the conduit at angles not necessarily normal to the fluid containment wall. A mechanism releasably attaches the second hollow support sleeve to the conduit. A mechanism, carried by the rigidified seal portion of the outer seal member and adapted to extend axially through the wall and the rigidified seal portion of the inner seal member, releasably attaches the inner seal member to the wall of the containment region. The inner seal member may be repaired or replaced without substantial outside fluid invading the containment region.

A second flexibly rigid, hollow support sleeve extends outwardly from the outer seal member and opposedly from the first hollow support sleeve, the first and second support sleeves having a degree of flexibility sufficient to allow for the insertion of the conduit at angles equal to or other than an angle normal to the fluid containment wall while maintaining a fluid-tight environment. A mechanism releasably attaches the second hollow support sleeve to the conduit. A mechanism, carried by the second securing plate, releasably attaches the inner seal member to the wall of the containment region. The inner seal member may be repaired or replaced without substantial outside fluid invading the containment region.

A tank sump has a one-piece body comprising a hollow base member for collecting fluids leaking from a piping system, the base member having an upper portion and a lower portion, and a hollow riser section having an upper portion and a lower portion, the riser lower portion extending upwardly from the base member upper portion, the riser section having sidewalls with alternately adjacent vertically extending wall portions and outwardly extending, U-shaped grip portions. An integrally formed cover is defined on top of the riser section upper portion. The cover may be cut off from the riser section of the body. A gasket may extend between the cover outer periphery and the outwardly extending grip portion of the riser section, and a mechanism removably secures the cover to the outwardly extending grip portion with the gasket therebetween, in a substantially water resistant sealing manner. The cover may alternately be cut away from the body and discarded. A substantially rigid lid is removably mounted on an outwardly extending grip portion of the riser section, and a mechanism mounts the lid to the outwardly extending grip portion in a substantially watertight manner.
