Holding tank vents are nothing more than a abs pipe thru the roof connected to a separate fitting in the top of the tank.
For a 2" grey water drain, needs a 1" or bigger vent pipe
For a 3" black drain, the vent pipe should be 1 1/2" or larger.
Then, like on RVs, the vent pipes could have a roof fitting mounted over them to keep leaves etc from falling in.
If the vents are not big enuff, no bigee,.....it will just suck all the sink traps dry, and you will wonder where the smell is coming from,....a problem on some RVs.
The FWT vents thru the filler fitting, or a separate fitting like this
