Awkward looking drain pipes ?

We're going to have to fix this because it keeps leaking. If I took the board out, the whole thing, metal flange, trap, and vertical pipe would drop and it would come completely apart. It's not attached, it just slides up and needs to be propped up.
If I run the water for more than a few minutes at full, or drain a sinkful, it will back up for a minute, and then it leaks. I guess over the flange. It also has a slow leak from the very top where the sink attaches.
What I'm wondering about is the extreme angle that the pipe goes back, more than 90 degrees, to go down the vertical. The second picture shows this. I took it parallel to the front pipe and trap, so you can see how much it turns. Is this too far? The vertical pipe can't move any further forward. It just looks odd to make it go around the trap AND around a curve. I'm wondering if it's getting slowed down.
This is an old house and we own it, so we're not planning on a major code redo, but I want it the most efficient as long as we're redoing it.

That silver/brass nut on there is a classic. That should be white plastic like the others.

Every part of the drain comes apart. B is the tailpiece from the sink. It could be rotted or cut too short. The tailpiece B slides into the tee fitting A which slides into C. You will have to loosen all three locknuts on the A fitting to see where the exact problem is.

Not even close to being right.
S traps have not been legal for years.
Two different materials for the drain.
Should have looked more like this.

I wonder if there is a vent?

I know the whole thing is freaked up. The only thing I wasn't sure about is the angle of the whole pipe on the way back horizontally. See "What I'm wondering about" on the sixth line.

We're going to take it all out and redo it anyway. I know the metal nut is old. I was just describing my troubles for the amusement of the forum.
Another crazy thing is that due to the settling of the house, the sink on the right has to drain uphill to the drainpipe on the left. You can actually see a bit of the wrong angle in the second photo. So we're starting from scratch anyway all the way up to the sink.

""This is an old house and we own it, so we're not planning on a major code redo, but I want it the most efficient as long as we're redoing it.""
We don't have a lot of money. I can't work. If we can install a vent I'll try. I already know that's a bad setup, but I was just describing it. I still need to know if the angle to the back of the cabinet is ridiculous but I don't see what else we can do with it. No one has answered my only question yet. Refer to the line halfway down------

""WHAT I'M WONDERING ABOUT is the extreme angle........""

There's no pipe up the back of the house by the sink. The house was built in 1905 so I have no idea how old that plumbing is or if it was done to code at the time. There are old iron pipes under the house but it's now all PVC.
Buy an AAV?

And redo it so you can install a p-trap instead of an s-trap.

Note: AAVs are not permitted by code in some areas.

I'm sorry your question appears to not be answered, but I am not following the "extreme angle" you are concerned with. As long as the vertical pipes all go straight into the connected pipe and any horizontal piped go straight into their connected pipes all should be fine.

I am not a huge fan of this type of drain. If it was me, I would do it all in schedule 40 PVC and weld it all together with AAV and P trap, but to each his own. I also would change the tail piece to metal and if your strainers are leaking, consider changing those out as well.

Does the sink have to drain toward the left?
Is there a limit to how LONG I can run pipes under the sink?
Can we make the right-hand sink the main one, tee the left one to it, then go back to the drain pipe with a P trap?
The pipes would take up more room, but it would keep us from having to tear up the damn floor inside the cabinet and extend the pipe in the crawl space. Before and after.

This is how it needs to be done as ray shows. That will eliminate the s trap...

Of course you will still use your side waste for the dual sinks...

This is the sharp angle I was referring to. At the bottom looking up. I saw other traps going in a loop under sinks on the internet, and they were the after pictures. So I guess it works. Might be a stupid question, but I wasn't sure if it would back up if I was running the water hard.

Do it as my pic shows with the vent. Use any sink you want as the main, but the left will be easier...

Cut that elbow off and glue a san tee to the correct height as shown..
May need a coupling and a piece of pipe..
Then another piece of pipe , then the vent..

Then pipe your sink normally...

That's why it won't fit with a P. The vertical pipe is too CLOSE to the left sink to add a P.

Is this the picture of the sink you are talking about?

Just add an a Tee and two 45 ells for the AVA so you clear the drain.

Street ells may be helpful in this situation.

This is the after picture. I thought you meant to put a P in the way it's put together in the before picture. Now I get it. Why not a center drainpipe? We're going to take it out and start fresh anyway because the pipes up to the sink are all messed up anyway. That would fit a P.

My husband made sure I was doing it right and gave me muscle once for taking the old stuff off but I did most of the labor.

Looks good but you forgot the vent that we stated numerous times..

You did not accomplish much then IMO...

Still an s trap that will have the trap siphoned,,,,

The old guy at Lowe's said I didn't need it, I was willing to buy it but my husband didn't care.

Never trust anything a Big-Box salesman says. We are correct. He is wrong.
