How do repair collapsed main sewer clay pipe?

You must find where the pipe is collapsed usually by snake in till you hit the

break or uncovering the pipe till you find the break. Cut both ends of the break

with a saw or chain cutter so you have a nice smooth end. Install a rubber

coupling on both ends slid onto your clay pipe. Measure and cut a replacement

piece of pipe to fit between, slide rubber boots over the seams and tighten.

Be careful not to over tighten and rebreak the pipe. Sewer lines have little

to no pressure so a snug tightening will do. Run water down line and look

for a leak. Cover and silt in dirt and you are ready to go.
