A drain assembly for a tank or containment vessel of the type having a flexible and removable interior liner. The drain assembly comprises a drain intake in fluid communication with a wall traversing portion. The drain intake is operatively deployable in proximity to the bottom of the tank and the wall traversing portion is operatively deployable through a wall of the tank. The wall traversing portion includes a conduit portion in fluid communication with the drain intake and with a location exterior to the tank. The conduit portion includes an interior stopper plate and a threaded portion. The drain assembly includes a hammer nut threadably receivable over the threaded portion when the conduit portion is received through the wall of the tank such that tightening the hammer nut upon the threaded portion causes the hammer nut to engage the exterior of the tank wall causing the stopper plate to compress the tank liner against the interior surface of the tank wall thereby securing the drain assembly to the tank wall and helping to prevent the unintentional leakage of the contents of the tank through the tank wall.

1. A drain assembly for a tank or containment vessel of the type having a flexible and removable interior liner, the drain assembly comprising: a drain intake in fluid communication with a wall traversing portion, said drain intake operatively deployable in proximity to the bottom of the tank and said wall traversing portion operatively deployable through a wall of the tank, said wall traversing portion including a conduit portion in fluid communication with said drain intake and with a location exterior to the tank, said conduit portion including an interior stopper plate and a threaded portion, said drain assembly including a hammer nut, said hammer nut threadably receivable over said threaded portion when said conduit portion is received through the wall of the tank wherein tightening said hammer nut upon said threaded portion causes said hammer nut to engage the exterior of the tank wall causing said stopper plate to compress the tank liner against the interior surface of the tank wall thereby securing said drain assembly to the tank wall and helping to prevent the unintentional leakage of the contents of the tank through the tank wall; andan interior plate, an exterior plate and a spacer, each of said interior and exterior plates and said spacer receivable about said conduit portion with said spacer positioned between said interior and exterior plates and said interior plate bearing against a first end of said spacer and said exterior plate bearing against a second end of said spacer, said interior and exterior plates positioned such that when said hammer nut is tightened upon said threaded portion said hammer nut engages said exterior plate, which engages said spacer, which engages said interior plate, causing said stopper plate to compress the tank liner between the stopper plate and the interior plate. 2. The drain assembly as claimed in claim 1 including a gasket positioned between said stopper plate and the tank liner, wherein tightening said hammer nut upon said threaded portion causes said stopper plate to compress said gasket against the tank liner. 3. The drain assembly as claimed in claim 1 wherein said stopper plate is continuous about the perimeter of said conduit portion and rigidly fixed thereto. 4. The drain assembly as claimed in claim 3 wherein said conduit portion includes a 90 degree elbow permitting said conduit portion to be received approximately perpendicularly through the tank wall and said drain intake to be positioned in close proximity, and with its opening approximately parallel, to the bottom of the tank. 5. The drain assembly as claimed in claim 4 wherein said threaded portion comprises a sleeve that is threadably received upon said conduit portion, said sleeve including exterior threads that permit the receipt of said hammer nut thereon. 6. The drain assembly as claimed in claim 1 wherein said drain intake includes a drain pan recessed within the bottom of the tank. 7. A drain assembly for a tank or containment vessel of the type having a flexible and removable interior liner, the drain assembly comprising: a drain intake in fluid communication with a wall traversing portion, said drain intake operatively deployable in proximity to the bottom of the tank and said wall traversing portion operatively deployable through a wall of the tank, said wall traversing portion including a conduit portion in fluid communication with said drain intake and with a location exterior to the tank, said conduit portion including a stopper plate and a threaded portion, said drain assembly including a hammer nut, said hammer nut threadably receivable over said threaded portion when said conduit portion is received through the wall of the tank wherein tightening said hammer nut upon said threaded portion causes said hammer nut to engage the exterior of the tank wall causing said stopper plate to compress the tank liner against the interior surface of the tank wall thereby securing said drain assembly to the tank wall and helping to prevent the unintentional leakage of the contents of the tank through the tank wall, wherein said stopper plate is continuous about the perimeter of said conduit portion and rigidly fixed thereto, and wherein said conduit portion includes a 90 degree elbow permitting said conduit portion to be received approximately perpendicularly through the tank wall and said drain intake to be positioned in close proximity, and with its opening approximately parallel, to the bottom of the tank, and wherein said threaded portion comprises a sleeve that is threadably received upon said conduit portion, said sleeve including exterior threads that permit the receipt of said hammer nut thereon; andan interior plate, an exterior plate and a spacer, each of said interior and exterior plates and said spacer receivable about said conduit portion with said spacer positioned between said interior and exterior plates and said interior plate bearing against a first end of said spacer and said exterior plate bearing against a second end of said spacer, said interior and exterior plates positioned such that when said hammer nut is tightened upon said threaded portion said hammer nut engages said exterior plate, which engages said spacer, which engages said interior plate, causing said stopper plate to compress the tank liner between the stopper plate and the interior plate. 8. The drain assembly as claimed in claim 7 including a gasket positioned between said stopper plate and the tank liner, wherein tightening said hammer nut upon said threaded portion causes said stopper plate to compress said gasket against the tank liner. 9. The drain assembly as claimed in claim 7 wherein said drain intake includes a drain pan recessed within the bottom of the tank.
