when someone comes back to the site with a fix and to tell us what worked or did not work. I do thank you for that.
I am glad you did the fix job. This sometimes is the culprit, the water was getting between the stack bonnet and the actual pipe and leaking in the home. Good job
Now, my concern is that you did not block the pipes ventillation job I hope. It needs to un obstructively ooze gasses from the plumbing. Do not block its job.
