Thetford discontinues the recirculating toilet

[JohnMD]

Dave,

I think you are on to something here. I like this idea and don't see why it wouldn't work or meet the requirements. For clarification, are you suggesting a vent to run inside the walls or along the walls. Inside the walls would be a pretty narrow vent, right? Not sure if there is a regulation on the size/diameter of the venting.
