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.

We claim: 1. 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. 2. The adapter of claim 1 wherein the first end is circular, for fitting into a circular hole entry port of an article; and, wherein the first end fits within the second end of a like adapter. 3. The adapter of claim 2 wherein the means for limiting rotation is a protuberance on the exterior of the adapter. 4. The adapter of claim 1 wherein the means for limiting rotation is a non-circular shape exterior of the first end. 5. The adapter of claim 1 further comprising: second means, on the exterior of the body proximate the adapter first end, for limiting rotation of the body in direction opposite to the direction limited by a first means of said least one means. 6. The adapter of claim 1 further comprising: at least one protuberance on the exterior of the adapter first end, for engaging the periphery of a circular-hole shaped entry port of the article, and for inhibiting withdrawal of the adapter from the entry port. 7. The adapter of claim 3 further comprising at least one protuberance on the interior of the body near the second end, for limiting the extent to which a pipe is axially insertable into said second end. 8. 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. 9. The assembly of claim 8 wherein the first end is male shaped and inserted into a female hole port of the article. 10. The assembly of claim 9 wherein the second end is female, for receiving a pipe; and, wherein the adapter first end fits within the second end of a like adapter. 11. The assembly of claim 8 wherein the article further comprises a buttress having a ledge proximate the entry port; and, wherein said means for limiting rotation of the adapter is a protuberance on the adapter body proximate the first end, for engaging said ledge. 12. The adapter of claim 8 wherein the means for limiting rotation is a non-circular shape exterior of the first end, wherein the article has a mating non-circular shape hole entry port. 13. The assembly of claim 8, wherein said at least one means on the adapter limits rotation of the adapter in a first rotational direction, to a point at which said major axes are vertically aligned; further comprising: second means on the adapter, for contacting a portion of the article and for thereby limiting rotation of the adapter in a second opposing rotational direction to a point at which the second end axis is vertically offset from and higher in elevation than the first end axis. 14. The assembly of claim 13 wherein the article further comprises a buttress having spaced apart ledge portions on either side of the entry port; wherein both means for limiting rotation contact said ledge portions, to thereby limit rotation as aforesaid. 15. The assembly of claim 9 wherein the entry port of the article is a hole, further comprising: at least one protuberance on the exterior of the adapter first end, for engaging the periphery of said hole, to inhibit withdrawal of the inserted adapter from the hole. 16. The assembly of claim 9 further comprising at least one protuberance within the hollow interior of the body near the second end, for limiting the extent to which a pipe is axially insertable into the second end. 17. The method of connecting a water-carrying pipe to a subsurface leaching system article having a base and a hole-port for water entry at an elevation spaced apart above the base, which comprises: inserting the first end of an adapter of claim 1 into the hole-port; and then selecting and carrying out the step of (a) rotating the adapter so said major axes are vertically aligned, to obtain a first invert elevation which is the maximum invert elevation achievable; or (b) rotating the adapter so said major axes are vertically offset, to obtain a second invert elevation which is less than said first invert elevation maximum but more than the elevation of the hole.
