I am going to be replacing a small section of underground sewer pipe that
runs from the front of my house toward the street. The existing underground
sewer pipe is 4-inch cast iron. I will be using PVC to replace the line
from the front of my house and connecting to that sewer line about 5 feet
out.

Can I use a Fernco coupling to connect the new PVC to the old underground
cast iron sewer pipe?

If not, how is that type of connection usually made?
