In all my years I've never had a sewer line explode so put your mind at ease there.

Let me walk you through the process. You will come off the sewer with either a wye or combination eighth bend and wye,(see images). You will prime and glue a 6" piece of ABS into each end of the fitting to be used. Now, with the pieces glued intothe fitting, measure end to end and add 3/8" an d that will be your cut. You will cut the cast iron with a hand grinder, a set of cast iron cutters or a Saws-All with a metal blade. Use Fernco Shielded Couplings,(see image)
do not use rubber couplings under ground. Slip the metal bands over each end of the cast iron and roll back the neoprene gasket on the cast iron ahead of the metal clamps.
Now place the fitting to be used in the opening and snap the neoprene gaskets over the bald ends of the fitting. Ypu may now slip the metal bands over the coupling and tighten the bolts. Be sure to give the branch of the fitting a little pitch before you tighten the couplings. More questions? I'm as close as a click. Good luck and thank you fer rating my answer. Tom
