Abstract
An adapter is used with a leaching chamber or like article to change the invert elevation for a pipe which carries water to the article. The first end of the adapter fits a hole or other port on the article. The body of the adapter rotates about that first end, changing the elevation of the second end relative to the base. Stops on the adapter body limit rotation: in one direction so the first and second ends are vertically aligned; and in the opposing direction so that the lengthwise axes of the first and second ends lie in an inclined plane. Thus, three positive invert elevations can be set for an inlet pipe for a particular article: a first and second at each limit of rotation of the adapter, and a third and lowermost elevation, wherein the adapter is not used.
Claims17
An adapter, for use with an article having a base and a water-entry port at an elevation which is spaced apart above the base, and for changing the invert elevation of a pipe which carries water to the article, wherein the article and adapter are suited for use with a subsurface leaching system which comprises:
- a first end, for connection to the elevated water-entry port of said article;
- an opposing second end, for connection to a water carrying pipe;
- a body having a hollow interior, for carrying water between the first end and the second end;
- the first and second ends having spaced apart and parallel major axes;
- wherein, when the first end is connected to said water-entry port, the first end is capable of being positioned in at least two different positions which are rotationally spaced apart about the first end major axis from each other, each different position having an associated different elevation of the second end major axis relative to the first end major axis;
- and,
- at least one means on the adapter proximate the first end, for limiting rotation of the adapter about said major axis in at least a first direction, when the first end is connected to a port of an article.
An assembly for use in a subsurface leaching system, which comprises:
- a subsurface leaching system article having a base and a water-entry port at an elevation spaced apart from the base;
- and,
- an adapter, having a first end connected to the water-entry port of the article, an opposing second end for connection to a water carrying pipe, and a body having a hollow interior, for carrying water between the first end and the second end;
- the first and second ends of the adapter having spaced apart and parallel major axes;
- wherein, when the first end is connected to said water-entry port, the first end is capable of being positioned in at least two different positions which are rotationally spaced apart about the first end major axis from each other, to thereby change the elevation of the second end major axis with respect to the base;
- and,
- at least one means, on the adapter proximate the first end, for limiting rotation of the adapter, at least in a first direction, when the first end is connected to a port of a an article.
