Hi,

I am going to start a project and I will be moving a toilet about 10' to the left.
Right now the toilet drian line is a 4" cast iron one. The questions I have are:

1. What do I use to connect the new line to the old cast iron one?
-I am hoping to use a ABS line for the new toilet drain.
2. I want to tie into the original drain so I am going to need to cut the cast
Iron. Will a saws-all work?
3. With the new distance (currant line about 2') (new line about 10') away
From the stack, I imagine I am going to have to cut the currant Y
Connection out... add a striaght piece and then put the new Y connetion
In to achieve the correct slope?

Thanks for any and all advice. As you can see by the terminology I have not done this before. :)

1. "What do I use to connect the new line to the old cast iron one?

I prefer PVC over ABS but your idea is sound.

2." I want to tie into the original drain so I am going to need to cut the cast
iron. Will a saws-all work?"
Since cast iron is very hard have lots of extra metal blades on hand and be prepared to spend some time. If you don't want the hassle rent a set of cast iron snap cutters if it's in a trench and easy to get to or a set of ratchet cutters if in a tight area.

3. "With the new distance (currant line about 2') (new line about 10') away
from the stack, I imagine I am going to have to cut the currant Y
connection out.... add a striaght peice and then put the new Y connetion
in to acheive the correct slope?"
With all that cutting renting a set of cast iron cutters makes good sense. Figure on 2 1/4" slope for a 10' run.
Use NO-Hub connecters, (see below) to convert from cast iron to plastic.
Good luck, Tom
