Re: Sewer Vent Cap
Kinda looks like a mushroom on the roof, right over the bath. It vents gases from the black tank, admits oxygen for aerobic sewage breakdown and maintenance of the trap water seals (P traps on your sinks) which prevent gases from entering the camper. It also provides equilization of the air pressure in the system so liquids (waste) flow where they're supposed to go.
Everyone has them on your roof at home too, but they don't usually have the mushroom style cap, just an open pipe. Sometimes called a "stink pipe"
