Leak in Cast Iron? Pipe under toilet...
I noticed that whenever the toilet's flushed, a pretty bad leak develops into the basement. I dried off the pipe, installed a new wax seal on the bowl and flushed - still bad. Dried it off again, stood under the pipe, son flushed it, and the leak comes from what appears to be a 2-3 inch "crack" in the piping. If it was coming from a bad seal, it would originate from where the bowl meets the floor---right? I see the crack leak - so I am pretty sure this is what it is - a crack!
It's a fairly large pipe that I believe it cast iron - certainly not PVC, copper.
I have heard JB weld may be perfect for this type of repair. I imagine that calling in a pro would cost a ton and I am looking for the best long term DIY solution.
