Update After hearing the input on vents, and seeing that there does appears to be a vent, or at least a roof penetration that looks like one in the adjacent laundry room, I'm thinking that adding what I guess is called a re-vent would be doable. Updated drawing below. Existing drain in BLACK...

Allllllllright. This is crossing into a territory beyond plumbing. I'll talk to the plumber who will be doing a job in another room about a sewer gas check in the house, and get their professional opinion on whether it's necessary, and I appreciate your concern. Beyond that, I'm not interested...

I get where you are coming from and I appreciate the spirit of your advice, but the binary you are proposing - it either 'works' or 'doesn't work' - doesn't actually exist in reality. It certainly doesn't exist in mine. The system as it exists 'works fine.' It doesn't work perfectly, or even as...

Update: There does appear to be a vent penetration in the roof above the laundry (the upstream end of the drain).

That's a great question. I'm not sure. Unfortunately all the plumbing is hidden under the floor, but above the 'belly', (combo rodent/moisture barrier +insulation). So it's quite hard to see what's there except where I open the floor. But I will look for a roof penetration above the laundry. If...

Ah this is great context. It would also explain potentially why the laundry room is sometimes randomly a bit stinky lol (Don't get me wrong, I'm not a fan of the situation at all, but I'm also aware that with a mobile home I have to work with what I've got)

I will open up the floor in a second joist bay tonight and get a better sense of what else is connecting to the line upstream of the intended new location, in terms of vents and/or other fixtures, and add that info here.

Thank you for your reply. Would adding a mechanical vent to the toilet arm (branch?) improve it appreciably, or would I need to add/join a roof vent to get the benefit? There is an adjacent vanity that I am thinking could be an easy location for a vent for the wc arm.

Would a mechanical vent in an adjacent cabinet (vanity) work?

Yeah, it's a mobile home so it's not surprising that it's not to code as-is, even though it's original construction. I even noticed the flange for the wc I just pulled dumped into a straight tee on its back. I'm pretty sure the venting on most of the system is subpar, too, given the number of...

Yes, upstream there is a washing machine in the adjacent room to the right. I assume that's the right-have terminus (upstream end) of the main drain line. To the left is another lav+shower+sink, although it's a room away and might be on it's own drain, I'm not sure. Thanks for your reply

As a longtime DIYer who has also worked in the trades a bit - but done only a tiny bit of plumbing - I'm considering moving a toilet as part of remodeling a 3/4 bath in my house. I had been planning to just leave all the plumbing as is, frankly because I was intimidated by it. But the subfloor...

So sorry to hear this. A man who teaches others is a great man indeed.
