I can't help but thank everyone who has written a review on the use of this product in sufficient measure. That's incredible. We tried repairing with two other new putties that didn't work. After reading these reviews we decided to try the recommended cannabis. We remade two joints with hemp on the top and bottom of this joint. It was nice to work. You can feel the difference in texture and gradient. You may feel a seal when tightening the key. We cannot recommend this product enough. Looking up through the hole in the ceiling and watching the water begin to flow again and stay dry as a bone was such a relief. I would never use anything else. Thanks again to everyone. You were 1000% right. This is the best and only plumber you will ever need.
