Venting DWV

I am in the early stages of planning my 2nd ground up remodel / build and was wondering about venting the plumbing.

Do you vent as you would residential plumbing for good flow into the tanks ? Or is there some specific way to vent RV plumbing ?

Both holding tanks will need to have a vent. They can have a common outlet in the roof, or be separate. If you have a center bath unit, a single roof vent would be enough for everything. If you have a rear bath unit, you should consider a vent for the galley sink drain, as well. That vent should be separate, only because it would be tough to run a vent pipe throughout the trailer just to make a single roof vent.

The plumbing principles are the same as they relate to vents in houses and RVs. Manufactures are guided (and regulated) by different building codes than residential contractors to be sure, but the principles of plumbing and electricity remain the same.

The plumbing schematics are widely available for every Airstream, and the same general principle applies in them all.

The drain lines to each holding tank are vented to ensure good flow from the sink,shower, or toilet to the tank by eliminating any vacuum in the lines.
