Simple reverse flow wye connector

A fitting, comprising:

• a body comprising:
• at least two separate openings on a first side of the body, wherein the at least two separate openings on the first side couple to corresponding separate passages in the body that converge to a common passage in the body;
• an opening on a second side of the body opposite from the first side of the body, wherein the opening couples to the common passage;
• and
• a bore in a part of the body between the at least two separate passages, the bore being concentric with the common passage;
• a diverter, wherein at least a portion of the diverter is located in both the bore and the common passage during use, and wherein a first end portion of the diverter is coupled to a drive mechanism on the first side of the body, and a second end portion of the diverter, opposite to the first end portion, comprises a tubular portion with an end of the tubular portion being open and in fluid communication with the common passage, and wherein at least part of the diverter in the bore tightly fits in the bore;
• and
• one or more seals positioned circumferentially around the part of the diverter that tightly fits in the bore;
• wherein the wall of the tubular portion of the diverter comprises an opening, and wherein the diverter is selectively rotated with the drive mechanism during use to align the diverter wall opening with a selected separate passage such that an object moving from the common passage through the tubular portion of the diverter is directed into the selected separate passage during use;
• and
• wherein the tubular portion of the diverter comprises orifices that allow at least some fluid flow between the separate passages not aligned with the wall opening and the common passage to equalize pressure between the passages, and wherein the orifices inhibit object flow between the passages.
