About to re-do toilet % shower pipe

Trucon01

I hate bumping my posts, but I would love to have someone chime in on my issue.

Let me know if you need more information or more pictures!

Thanks,
Jeff

I gave you an illustration of an acceptable venting method for my code- the common vent is positioned to vent both fixtures. Your illustration would not pass my code standards because the vent is laying flat plus it is only venting the toilet. Would it work? I don't know.

Sorry, I did see your post, but was curious if a single vent would work, like in the drawing i added. Now I know it wont.

By your drawing, it looks like my materials would be:

QTY
1 4" PVC pipe
1 4" x 2" wye
1 4" x 4" x 2" x 2"
1 2" pipe (I can cut to length)
1 P trap assembly
1 90 degree long sweep
1 closet flange
1 4" furnco (connecting to cast iron)

Does this sound about right?

Also, does the Furnco need to be fully shielded or can it just have 2 straps if its going to be buried?

I've labeled the fittings for you-
When connecting plastic to cast iron inside the house, I like to use a shielded 4" cast iron x plastic coupling- code in my area. Others use a 4" fernco. Be sure the pipe has the outside scale removed or your seal won't be water tight

Thank you!!

Where the pipes have a 4 way intersection, what is that piece called? A 4x4x2x2 sanitary cross?

That's not really an intersection- the line going to the shower is higher in elevation then the lower line so it is just drawn over the top.
As I said earlier- the tee for the shower can be rotated 360* - wherever the shower sits
