Quick question about a basement bathroom that was roughed in with a 2" trap below the concrete and a 2" stub sticking above the concrete. I cannot see how the trap is vented but the nearest vent is from the rough in for the sink which is 2" with a clean out. Then has a reducing sani tee down to 1 1/2" vent where the sink drain ties in. I have created a dap out but got to thinking about the venting and whether it was proper. Any help is appreciated.
Here is a simple pic of the layout.
