Toilet Vent Scamp 1987 19'

[Tcjmiami]

I have replace the Toilet in my scamp.
I have a vent through the wall behind the Toilet that looks like a round House Soffit Vent made from stamped Al.

There is no pipe or flange inside at all and I want to hook it to the outlet on my Toilet.

What do you recommend.

Thank you.

I installed a vent pipe through an added vent on the top of my Scamp (added front bath).

Thank you but I want to use the existing hole that is less than a foot away.

Then plumb it up, but the sewer gas is better farther away and in the breeze.

What did you replace the toilet with? The same setup that scamp uses? A different toilete? How can anyone suggest how to plumb the vent without knowing the details?

My tank is different, but they included a vent that glued to the top of the tank to attach the vent pipe to and from there is is a matter of plumbing the PVC DVW pipe to wherever you want it to go.
Do you have a 1 1/2" or 2" vent outlet on your tank? If not you have to install one.
The first thing to install one would be to determine what the tank is made of so that a compatible vent can be installed on the top.
Once you have the vent (if you do not already have one) then is is a matter of running the vent where you want it to go.
Here is one for ABS (many or most are ABS):

Not an exact answer but I just completed a house remodel and did not want to run additional plumbing vents through the roof. So instead I installed a "studor vent". Its essentially a check valve that allows air to enter when draining. No outside vent is required.

Leaving an open wall vent like you have connected to the toilet means you will "enjoy" that special odor at human level, instead of away from people up out the roof of the camper. Me, I'd try a studor vent instead if your objective is to eliminate the roof penetration. The official term is "air admittance valve". Studor is just a brand.

There are two issues
1. Venting the tank so that it will drain quickly
2. Keeping odors outside and away from the trailer.

I routed the vent from the black tank behind the wall (new) and to the top of the trailer so that there would be a draft to help the fumes be drawn up and out instead of through the valve and into the interior when flushing. The idea is that when the flush valve is opened there is a slight flow out of the trailer and up the vent. Having the Fantastic fan on helps to "pressurize" the cabin slightly to boost the flow.

Of course the side vent will do the same thing to some extent, but the gasses are then next to the trailer.

I think that Norm made a swiveling vent cover for his Scamp so that he could flush the black tank from outside while draining the tank and that would be one "feature" of the side vent.

I don't know what the standard Sea Land toilet tank is made from, but you may have to add the tap for the vent to accomplish your goal of venting however you want it to go.
