A yoke vent, basically an offset relief vent, may be installed on every 5th floor from the top floor downwards. A pipe connecting upward from a soil or waste stack to a vent stack for the purpose of preventing pressure changes in the stacks. A yoke vent is any pipe that connects upwards from a soil stack or vertical waste stack to a higher location in order to prevent pressure changes in the stack pipe.

Those pressure changes could prevent proper drain venting. In a typical arrangement, a yoke relief vent or yoke vent is constructed by using a 45 degree wye on a soil pipe or waste stack.

The wye points upwards and connects using a second degee connecting wye to a separate vertical vent stack pipe at a point higher in the building and usually above any other branch vents that connect to the same vent stack. The yoke vent pipe diameter is typically the same as per code below or one pipe size smaller per local authority than the drain and vent stacks to which it connects. The upper section of the offset shall be provided with a yoke vent.

The diameter of the vents shall be not less than the diameter of the main vent, or of the soil and waste stack, whichever is the smaller. Loop vents may be used at island sinks or "free-standing sinks" where there is no direct route from above the sink's flood rim to a vertical vent stack. To keep the loop vent dry, that is so that the vent can work without flooding, the loop vent has to connect at the top of the fixture's vertical drain line, and the horizontal portion of the revent pipe must be at least 6-inches above the flood rim of the sink or other plumbing fixture being vented.

The flood-rim is the highest possible point that water can rise in the fixture, or the actual horizontal rim of the sink if there is no sink overflow feature. That is, dry vent piping carrying only air, sewer gas, or moisture to above the roof line is unrestricted. However the piping does need to be protected from nails - use nail plates to protect vent and drain piping both where where piping passes through studs, joists, or rafters.

Special routing and connections are required for proper venting of plumbing fixtures such as kitchen island or peninsula sinks or dishwashers - plumbing fixtures that are located where a direct vertical vent stack connection is not possible.

But I think that your inspector says that plumbing vent tee connections like those I show in our illustration are installed upside down so that water down a wet vent won't fully drain into the vertical drain line and vent stack. Follow the vent piping in your building, locate all joints, connections, tees, photograph them, and post photos here or ask the inspector to be more specific if some but not all connections were improper.

Our illustration shows the proper as well as an "upside down" position of a plumbing vent tee. Note that if the tee, seen at the vertical plumbing vent riser, were upside down, water would be trapped in the horizontal piping, ultimately inviting clogs.
