I want to move my laundry room into another room. I know I have a cast iron pipe running down from the upstairs bathroom. Can I tie into that pipe or do I need to do something different?

You may tie into the stack providing you vent the washer. This vent can,
1. Be run out the roof
2. Revented back in the attic to a existing roof vent.
3. Revent back to a existing dry vent. **OR**
4> If AAV's are allowed in your code you can install a Studor Vent. Good luck, Tom

Im not sure what studor vent is but Im moving the washing machine into a room next to the exsisting plumbing. Can I run the vent over about 4 ft. to the old vent or would it need to go straight up? It's a tri-level house so I would have to go out the roof. It may not be that big of a deal beause the cast iron pipe I want to hook to has a pan it runs through that sticks out of the wall a little.

A SAtudor Vent is a air admittance valve, (AAV).

Please explain. Are you saying the cast iron pipe is open at one end and drains into a pan? Sounds more like a drain then a vent. Check with your local Building Department to see if AAV's are allowed in your area, That might be your best bet, Regards, Tom

Im sorry Im not very good at explaining this and I don't know the proper names of things. The cast iron pipe is a 4in. Or 6in. Drain from the 2 upstair bathroom. I think there are vent pipes running from those upstair bathrooms in a trough in the wall. I know I should I know more but I didn't want to start cutting wholes in the walls. What I was thinking since you said I could hook up to the cast iron drain then maybe the I could run the vent through the trough which I beleave runs all the way to the roof.

You're doing just fine Bamalady. I can figure out what you meam.
I'm going to put up a image of a washer set up that you will have to build. You haven't told me yet exactly how you plan on connecting the washer to the cast iron. How do you plan on connecting to the cast iron?
You may run the vent in any one of the 4 options I have given you.
Back to you, Tom
