Vent and/or drain Pockets by horizontal reducers (eccentric)

The location of the side parallel to the axis will be located upward or downward based on the opposite vertical piping running of the large size of the reducer:






If the vertical piping of the large size running upward the flat side shall be installed with continuous horizontal bottom in order to avoid drain pocket































If the vertical piping of the large size running downward the flat side shall be installed with continuous horizontal top in order to avoid vent pocket.



































Avoid install concentric reducers in horizontal piping
