Hi,
Homeowner and DIYer here. The master bedroom and bath were added in the 1970s. The bathroom sink is on an outside wall. I noticed water on the concrete outside. I removed the siding. At first I thought that the leak might be in the ABS-to-cast iron joint that I installed when I remodeled the bathroom in 1998. However testing showed that the leak is at the bottom of the short cast iron pipe. I had to chip away some mortar to confirm that the cast iron is sitting in a rubber gasket wrapped in stainless steel at slab level. There has been other minor shifting of this wall so there could be an alignment issue, though I don't see an obvious displacement.
What are my options here? Is there some compound I can use to seal the rubber to the cast iron? Should I try to expose enough of the rubber to get a pipe clamp around it? Do I need to replace the cast iron section with ABS?
Thanks for your thoughts,
Mark
