Black tank and pipe

[cwthompson2000]

Newby question. The pipe coming from my black tank is a size that I can't find any connections for. I believe it's 4" as opposed to td he standard 3". Is 4" standard on the Glen Brooke or did the PO change to something unique? I've looked everywhere on the net for some kind of adaptor and haven"t found anything. Any suggestions appreciated!!!
TIA
Chuck
