My 1963 house has Iron pipes. The Clean-out for one of the drains had a PVC plug in it that I removed today. The threads in the Iron pipe are rusted beyond use.
Right now I have an OKAY products rubber expender plug in it. What is the best way to solve this besides tearing a hole in my wall and wallet? |
You could remove the cast iron clean out from the hub of whatever fitting it is in (assuming it is installed in that manner). It's sealed in there with what is most likely a couple layers of lead and oakum. You can generally pry/dig it out a layer at a time with a screwdriver and hammer. Just be careful no to ham fist it.  Once you do that and remove the clean out fitting you can install a new PVC clean out.
To install the new one you'll need a PVC cast iron hub adapter and a PVC clean out. You'll also need something to fill/seal the joint. I generally use a product called Oatey "Pipe Seal" for that purpose, part number 30614. ETA: The solution you are currently using is most likely fine, even for a "permanent" fix. The only thing I would caution you about is the potential for the expanding plug to come out in the event of a sewer back up.

An iron cap would do. They are an iron center with a ring of lead around it . The din is threaded but made of lead so it's easily deformed. Put on pipe, twist to get the threads started, mash with hammer to seal. A great percentage of sewer lines I work with are done this way.
However, the dollar plug (the rubber expanding plug) is perfectly fine and you should have no issues using it. I'm pretty sure it's legal everywhere. |

Quoted: I'm thinking of jb welding in a cut down 1 1/2" pvc female thread so that I can use a 1 1/2" plug It'll seal fine and these are used for permanent solutions all the time. |
