In one of my main lines I have a small leak at a kbi turnoff valve. This is a large diameter device with a 8" turning lever on top. It can be used to manually turn off water to one section. It appears that this device is glued to the 2" pipe on both ends. But, it looks like you could unscrew each end and remove the center part. I am not interested in removing the center part put maybe I could tighten it up and stop the leak. I would need an 10" pipe wrench to grip the thing. Is anyone familiar with this device? Someday I will learn to put photo up sorry.
