Abstract: A connection adapter for incorporating in a riser stack of an underground tank includes a first portion, a flange portion, and a pipe stub. The first portion has a bottom end and a top end opposite the bottom end. The bottom end has an outer diameter sized to fit within an accessway of the underground tank. The flange portion is connected to the top end of the first portion. The pipe stub is in fluid communication with the first portion and externally protrudes from the first portion. The pipe stub is integrally formed with the first portion and has an integrally formed distal end wall caps the pipe stub.

Abstract: A solids interceptor and methods of using the same. The solids interceptor includes a tank including an open end, a wastewater inlet, and one or more wastewater outlets. A basket assembly is removably attachable to the tank via the open end between an operable position and a removed position. The basket assembly may seal the open end when in the operable position and expose the open end of the tank to a surrounding environment when in the removed position. A first and second outlet may extend away from an interior of the tank in a first and direction, respectively, with the second direction being oriented at an angle with respect to the first direction. The basket assembly may include a seal that is compressed about a circumferentially extending corner provided on the tank to thereby seal the open end of the tank and the plumbing system.

Abstract: An improved solids interceptor and methods of using the same. The solids interceptor includes a tank having an inlet and at least one outlet, and an access opening on an upper end of the tank. A perforated basket is removably received within the tank via the access opening. When the basket is installed within the tank, wastewater entering the tank via the inlet flows into the basket, with the solid waste being collected in the basket and the liquid waste flowing out of the basket via the perforated screen. The basket and tank include an interlocking flange assembly that automatically axially aligns a basket inlet with an inlet pipe simply by inserting the basket into the tank. The basket is removable from the tank to easily clean out and discard solid waste accumulated in the basket.
