ABSTRACT:
A trap apparatus associated with a drain comprising a fluid inlet, a first chamber, second chamber, a fluid outlet and a structure for retaining fluid. The fluid inlet is capable of accepting in flowing fluid. The first chamber member is associated with the fluid inlet. The second chamber member is associated with the first chamber member and is joined thereto at a transition region. This transition region is configured to facilitate radial flow from the first chamber member through the transition region and into the second chamber member. The fluid outlet is associated with the second chamber member. The retaining structure retains fluid in the transition region so as to maintain the transition region submerged. The invention further includes a drainage trap.
