How's this venting look?
 
Here's a rough diagram of how my plumbing is, typical cast-iron, 1950's stuff.

A buddy of mine is convinced that it's improperly vented, and will clear the S-trap out, yadda yadda yadda.

"code" or not, just looking at it, the venting seems adequate and no siphon-effect will occur. He claims the toilet should have been on top of the other Y's???

I want to redo it in PVC, I planned on just pretty much replicating that, or would you do it differently?

I've never had running water in this house yet, but I'm sure it must have been fine for the previous owners if they used it for 50 years...

Does the sink have a vent?

1. Hopefully they are sanitary Ts not Ys.
2. Hopefully you have P traps and not S traps which will suck dry.
3. The arrangement shown is great provided they are sanitary Ts and the length between the p trap and the main stack is within your local code requirements for the diameter pipe. For example our local code requires the distance between the toilet flange and the vent to be no more than 6 feet for 3" pipe. That main stack does go up through the roof right?
4. Why are you ripping out cast iron?

A little better pic. 2nd sink is the kitchen, 20ft or so away
One quick q... if these sanitary t's are all right angeled, how do you achieve the sloping pipe? Wouldn't it all be horizontal or is the T slightly angled?

Will it be ok as above? Do I need to vent the TUB somehow? It's 5-feet away, within code, but still...?

Yeah, I forgot what the local code was but it was a few feet. The toilet is 1-foot off the stack. Sink is maybe 2-foot. Yeah the stack goes through the roof.

I didn't like the looks of the joints, plus I had the walls torn out and I figure PVC will outlast me so I'll never have to mess with it again.

I appreciate your help.
