This house was built with a kitchen sink, bath sink, and toilet/tub on a 4" CI, with a 3" (might be 2... cant remember) CI roof vent.

About 40 years ago it was remodeled.

On the original drain line, they left the tub and kitchen sink, and added a washer.

On the new drain line they put 2 toilets, 2 bath sinks, and a tub.

I can find no evidence that that second drain system has a vent. It for sure isn't going through the roof, and I'm fairly sure it's not going through the walls to the original vent. I tested this by filling tub 2 up half way, and putting my ear near the old toilet connection on the original vent (they left the stub on the vent open when they moved it). I heard zero air gurgling in that vent when tub 2 is drained, and I 'DO' hear air gurgling when I drain tub 1 and the washer.

This leads me to believe that the 2nd drain system isn't vented. Good assumption?

If I could move the kitchen sink and washer to that 2nd drain system, it would help with another project. Is that possible?

"If" the 2nd drain system isn't vented, it would be great if I could move it over and have everything work like it has been working.

If venting issues show up, could I solve those issues by putting a tee on the washer/sink drain, and run a pipe over to the original CI vent?

Good Lord have you got a task ahead.
Firstly "successful" plumbing" looks organic, straight runs with smooth curves and downstream joins. Now - can you get to the drains to do this? Are you a willing to trace the drain lines and open the walls (and penetrate the roof decking) where necessary to get everything fixed?

Not sure if I'm following you, or perhaps my description/drawing wasn't clear.

The drawing is top down... it's just a 1 story house, and all the connections are in the crawlspace. Both drain pipes and the connections are in the same area... maybe 12 feet apart.

I was asking if I could move the kitchen sink/washer line from the original drain to the new one. If so, can I put a tee on that washer/sink line and tap into the original vent if necessary?

The only thing I would be installing is the line that says 'planned' (and a vent line if necessary). I probably should have used a different color on the existing fixtures... those aren't moving.

I think I made my initial post too complicated. Here is a simplified version of what I want to do.

Everything is vertical except for the two drain pipes, and the line I want to cut. Also, there is a vent at washer/sink 1 that I forgot about.

Any ideas on this? Here's a more concise diagram for what I want to do:

I'm just working with how the house was built. Function wise there haven't been any problems in 41 years for drain 2, and 50+ years for drain 1.


Is there anything more specific you can say?
