its in a place i cannot get to without knocking down a wall and ceiling - is there anything i can pour down the drain to stop the leak at the joint - its a very small drip
there,s nothing you can put in it to stop the leak. you might be able to shut the water off and run a new line.
Is this a joint inside the wall? If It is, is there any way you can measure down the wall and cut a small hole and see the joint? I have fixed pvc using a soldering iron even with pressure in the pipe. I wish I could see it.
Is there anything you can pour down the drain - no. And if there was I wouldn't recommend you use it - too likely to cause a blockage further along the line. You're going to have to open the wall and get in there and fix it.
