At least one of the first or second ends comprises a non-circular sectional shape having a low flow enhancement channel disposed at a bottom. The low flow enhancement channel is configured to comprise a first depth of a fluid that is greater than a second depth of the same fluid in a substantially circular section pipe where the non-circular sectional shape and the circular section pipe comprise substantially the same overall cross sectional area. A stand may be associated with the pipe fitting, the stand configured to accept the pipe fitting body in an orientation where the low flow enhancement channel is disposed at the bottom of the non-circular shape. ## Claims ### Claim 1 A pipe fitting, comprising: a pipe fitting body comprising a first end in fluidic communication with a second end, where the first and second ends are each configured to receive a pipe; wherein at least one of the first or second ends comprise a non-circular sectional shape; and wherein the non-circular sectional shape comprises a low flow enhancement channel disposed at a bottom of the non-circular sectional shape. ### Claim 2 (depends on 1) The fitting of claim 1, wherein the low flow enhancement channel comprises a first radius smaller than an upper or a middle radius of the non-circular sectional shape. ### Claim 3 (depends on 1) The fitting of claim 1, wherein a first area defined as comprising a lower half of the non-circular sectional shape is less than a second area defined as comprising an upper half of the non-circular sectional shape. ### Claim 4 (depends on 1) The fitting of claim 1, wherein a first area defined as comprising a lower third of the non-circular sectional shape is less than a second area defined as comprising a middle third of the non-circular sectional shape. ### Claim 5 (depends on 1) The fitting of claim 1, wherein a first area defined as comprising a lower third of the non-circular sectional shape is less than a third area defined as comprising an upper third of the non-circular sectional shape. ### Claim 6 (depends on 1) The fitting of claim 1, wherein the low flow enhancement channel is configured to comprise a first depth of a fluid that is greater than a second depth of the same fluid in a substantially circular section pipe where the non-circular sectional shape and the circular section pipe comprise substantially the same overall cross sectional area. ### Claim 7 (depends on 1) The fitting of claim 1, wherein the non-circular sectional shape comprises an oval or an ellipse. ### Claim 8 (depends on 7) The fitting of claim 7, wherein a major axis of the oval or ellipse is oriented vertically. ### Claim 9 (depends on 1) The fitting of claim 1, wherein the non-circular sectional shape comprises a triangle. ### Claim 10 (depends on 9) The fitting of claim 9, wherein an angle of the triangle is oriented at the bottom and a side of the triangle is oriented at a top such that the side is oriented substantially horizontal. ### Claim 11 (depends on 1) The fitting of claim 1, wherein both the first and second ends comprise the non-circular sectional shape. ### Claim 12 (depends on 1) The fitting of claim 1, including an outside orientation feature attached to the pipe fitting body. ### Claim 13 (depends on 12) The fitting of claim 12, wherein the outside orientation feature comprises a fastener aperture vertically disposed in relation to the non-circular sectional shape. ### Claim 14 (depends on 12) The fitting of claim 12, wherein the outside orientation feature comprises a spike vertically disposed in relation to the non-circular sectional shape. ### Claim 15 (depends on 12) The fitting of claim 12, wherein the outside orientation feature comprises a stand horizontally disposed in relation to the non-circular sectional shape. ### Claim 16 (depends on 12) The fitting of claim 12, wherein the outside orientation feature comprises an auxiliary tool receiver, such that an auxiliary tool may be removable attached to the auxiliary tool receiver. ### Claim 17 (depends on 1) The fitting of claim 1, including a stand associated with the pipe fitting, the stand configured to accept the pipe fitting body in an orientation where the low flow enhancement channel is disposed at the bottom of the non-circular sectional shape. ### Claim 18 (depends on 1) The fitting of claim 1, wherein the non-circular sectional shape comprises an inside of the pipe fitting body and an outside of the pipe fitting body comprises a circular sectional shape. ### Claim 19 (depends on 18) The fitting of claim 18, wherein the pipe fitting body comprises a resiliently flexible and compressible material. ### Claim 20 (depends on 1) The fitting of claim 1, wherein the pipe fitting body comprises a bend. ### Claim 21 (depends on 20) The fitting of claim 20, wherein the bend is substantially horizontal or vertical. ### Claim 22 (depends on 1) The fitting of claim 1, including a third end in fluidic communication with the first and second ends, the third end also configured to receive the pipe. ### Claim 23 1 A pipe fitting, comprising: a pipe fitting body comprising a first end in fluidic communication with a second end, where the first and second ends are configured to receive a pipe; wherein at least one of the first or second ends comprise a non-circular sectional shape; and wherein the non-circular sectional shape comprises a low flow enhancement channel disposed at a bottom of the non-circular sectional shape, wherein the low flow enhancement channel is configured to comprise a first depth of a fluid that is greater than a second depth of the same fluid in a substantially circular section pipe where the non-circular sectional shape and the circular section pipe comprise substantially the same overall cross sectional area. ### Claim 24 A pipe fitting, comprising: a pipe fitting body comprising a first end in fluidic communication with a second end, where the first and second ends are configured to receive a pipe; wherein at least one of the first or second ends comprise a non-circular sectional shape; wherein the non-circular sectional shape comprises a low flow enhancement channel disposed at a bottom of the non-circular sectional shape, wherein the low flow enhancement channel is configured to comprise a first depth of a fluid that is greater than a second depth of the same fluid in a substantially circular section pipe where the non-circular sectional shape and the circular section pipe comprise substantially the same overall cross sectional area; and a stand associated with the pipe fitting, the stand configured to accept the pipe fitting body in an orientation where the low flow enhancement channel is disposed at the bottom of the non-circular shape. ### Claim 25 A non-circular pipe, comprising: a pipe body comprising a first end in fluidic communication with a second end; the pipe body comprising a singular cross sectional shape between the first end and second end; wherein the singular cross sectional shape comprises a non-circular sectional shape; wherein the non-circular sectional shape comprises a low flow enhancement channel disposed at a bottom of the non-circular sectional shape, wherein the low flow enhancement channel is configured to comprise a first depth of a fluid that is greater than a second depth of the same fluid in a substantially circular section pipe where the non-circular sectional shape and the circular section pipe comprise substantially the same overall cross sectional area, such that a waste blockage is prevented or reduced from accumulating along the bottom of the non-circular sectional shape as compared to the circular section pipe. ### Claim 26 (depends on 25) The pipe of claim 25, including a stand associated with the pipe, the stand configured to accept the pipe body in an orientation where the low flow enhancement channel is disposed at the bottom of the non-circular sectional shape.
