Forum Title: Photo - Is this a vent or sewer drain out ?
Hi, I am trying to figure out if this is a sewer drain out or a vent. I want to attach a rv dump to it if it is a sewer drain out. Thanks for any help

stick a hose in it and see if it drains or not,,

Honestly, I have no idea, but the cap tells me it probably is not a vent. If it was a vent, would it be capped?

Maybe it had a purpose and is longer used. That low heel outlet 90 is not normally used in that position. So someone not really knowing what they where doing probably installed it.
