Basement bathroom plumbing

[brod99]

I am trying to add a basement 1/2 bath and move a floor drain. I am wanting to know if I can tie both lines into a line that goes from the main stack to a current floor drain and seal the old drain off. Also, I want to know if I need to add a vent or not.

If it is 3″ are bigger you can conect to it, but you need a vent. Check your local code, let me know.

The pipe I am tieing into is 4″ cast iron. I need to add two y’s into it going different directions. Do I have to use cast iron or can I use pvc y’s and what do I use to connect them to the pipe? Thanks.

You use nohub bands are fernco bans. Also you have to vent the plumbing. Let me know.

You can use PVC fittings, if your code alows it.
