ABSTRACT:
A multi-use adapter ring for converting the compatibility of an access opening of an underground on-site waste or drainage facility tank surface or component so as to receive a lower end of a riser component, in a tongue-and-groove type connection, to help achieve and maintain a vacuum tight, water-tight seal. The multi-use adapter ring has a first vertical cylindrical wall, a second vertical cylindrical wall having a height less than the first vertical cylindrical wall and spaced radially outwardly from the first vertical cylindrical wall, and a plurality of radially-extending ribs arranged between the first and second vertical cylindrical walls. An inner ledge is provided inwardly of the first vertical cylindrical wall. The first vertical cylindrical wall defines a male connection end to engage, in a substantially vacuum-tight manner, a female connection end of a riser component, such as a riser, a riser pan, or a riser cover.
