Repairing Cast Iron Sewage Line Joints

The original poster noticed weeping joints with deteriorated packing in their cast iron sewage line and sought advice on resealing them.

Suggestions included cleaning out the old packing and using caulking or epoxy putty.

Replacement Options

Several users recommended replacing the entire run with Ferncos and PVC or ABS, suggesting it's a more permanent solution.

Cutting out the old leaking piping with a Sawzall and replacing it with ABS coupled with "no hub" rubber couplings was mentioned as a standard practice.

Professional Consultation

One user advised consulting with a local plumber to determine the condition of the cast iron and whether re-caulking is sufficient.

It was also noted that if the joints are failing, the rest of the cast iron might be in poor shape, suggesting a full replacement is needed.

Alternative Solutions

Repacking the joints with OAKUM and resealing them was mentioned as a practical option.

Update and Resolution

The original poster updated that the leak was at the top by the flange and resolved the issue by replacing the wax ring and installing new toilet flange bolts.

The floor was soft, requiring longer screws for secure installation.

The lead joint at the flange was still tight, but the flange was slightly crooked.

After the repair, there were no more leaks.
