Abstract:
A kit of materials to make a support for one or more manhole rings during a concrete pour around a prefabricated grease interceptor includes a base, a plurality of vertical supports, and a peripheral grid to surround a top of the prefabricated grease interceptor at a position to support a manhole seating ring. The vertical supports are long enough that they extend from the base to the peripheral grid for most grease interceptor installations or can be cut to size to position the peripheral grid.
Abstract:
An apparatus for separating FOG from grey water in an effluent includes a housing having a first end having two plumbing fittings and a second end having one plumbing fitting. A baffle mounted inside the housing at the second end forms a barrier to flow of liquid toward the plumbing fitting on the second end above a certain height, and allows the flow of liquid past the barrier toward the plumbing fitting on the second end below the certain height. A conduit allows flow of liquid from past the baffle to one of the plumbing fittings on the first end. A plug closes one of the three plumbing fittings, and leaves the other two plumbing fittings available for connection to plumbing from a source of effluent and an outlet for grey water, respectively.
