Appl. No.:

09/662473

Inventors:

Kristen K. Hedstrom - Grove City OH
Terrance H. Gray - Bath ME
William V. Shaffer - Powell OH

Assignee:

PSA, Inc. - Topsham ME

International Classification:

E02B 1300

US Classification:

405 48, 405 43, 405 46, 405 49, 138105, 138155

Abstract:

An adjustable coupler interconnects leaching chambers to create a serpentine pathway for a leaching field. The coupler can comprise a mating feature, which can be used to mate the coupler between a first leaching chamber and a second leaching chamber, and an adjustment feature, which can adjust the angle between the first chamber and the second chamber between a range of angles. Either, or both, features can include a swivel connector mateable to an end of one of the chambers. The range of angles can be particularly chosen to be about 45Â. More particularly, the range of angles can be about 22. 5Â in either the clockwise or counter-clockwise direction.
