So I recently had a dead cat get into my walls and we had to tear out the primary wet wall in the house between the kitchen and front bathroom (read more about it here)...

Anyways, in the midst of re-framing, it was a good time to look at the plumbing that was done by what I can only gather were some serious drug addicts in the 1970's. It turns out that the back bathroom (adjacent to the front bathroom) has no drain venting!! Since I will be doing some roof repairs at the same time, it's a good time to re-think the location of the vent pipes where they penetrate the roof (since they're too close to the valley for a good seal)...

Here's a look at the old vent pipes for the front bathroom.

So here's the question: Currently the bathroom, kitchen sink, and laundry room each have their own vent. I'd like to tie in both bathrooms (when I eventually GET to working on the back bathroom), and the kitchen fixtures into a single vent pipe that I'm showing below:

how the heck does a DEAD cat get ANYwhere?
i think you mean he was ALIVE when he went in, but commited suicide by ingesting lost hippie stash found in wall when he saw your venting problem, thereby allowing his rotting, stinking corpse to bring your attention to this problem. quite a helpful cat, i dare say.
i hope you buried him with honors.

LOL!! Yeah, I think he may have been alive when he crawled up a tiny hole on the outside of the house! We buried him in our back yard at around midnight. I still wonder what our neighbors were thinking!!

oh, and i see no reason why your idea won't float, although there could be variables i don't see.
the plumbers who actually get PAID to do these things will chime in if necessary, i'm sure.
i'm just a plumber because i have to build this home, and i have to be an electrician...and a carpenter...and a drywaller...and a painter...and a roofer, and cement guy, and chainsaw guy, and, and, and.... when i'm done, i'll be back to repairman/musician....

I am confused, what are you trying to do......and for the off topic......A cat>how did that happen?

I'm trying to add venting to an additional bathroom that was built in the 1970's without one --but I'd like to combine all the drain venting from both bathrooms and the kitchen to a single vent pipe that goes out the roof. I'm relocating the original roof pipe but I'd like to combine the vents to save work on having multiple roof penetrations...

About the cat, if you read the post in my signature, I explain it all there but the cliffs are that he found a small hole in the outside wall where plumbing was somewhat exposed & found a way in there!

I did some more work in the area and thought I'd take a new pic and add some lines to better show what I'm trying to pull off...
