Old Cast Iron Soil Pipe Weeping

The pipe must have a miniscule crack. The casting is very irregular which complicates the use of rubber sealing tape. In the past I have used JB Waterweld successfully but not this time. The water seeps out too fast for the epoxy to set. Perhaps the waterweld sets too slowly. Your ideas much appreciated. Thanks. Frank from MA

I'm not a plumbing pro, but it seems to me if water is the only thing screwing up the WaterWeld, why couldn't you just wait several hours until the soil pipe stops weeping before beginning the job? And obviously not put any more water down it during this time.

Can you use a rubber repair coupling? Something like this?


If it's cracked though, cast iron tends to just keep getting worse. You'll have to plan a replacement at some point.

How about no more Band-Aid repairs and replace the bad section of pipe. When cast iron starts to leak it has been corroded from within. The first leak is just the first of many to come.
