Remove Old Valve and Compression Sleeve

What happens here

With the supply lines disconnected, use the angle stop wrench to remove the large back nut that secures the old angle stop valve to the copper water pipe. Once the nut is removed, the old valve can be pulled off. The old compression sleeve and ferrule will likely remain tightly pressed onto the copper pipe. To remove these, use a compression sleeve puller tool. Extend the puller completely, slide it over the copper pipe, and thread the nut of the puller onto the existing pipe threads. Then, use a 1/2 inch ratchet wrench to turn the puller's nut, slowly pulling the compression sleeve off the pipe.

Goal: Completely remove the old, leaking valve and its components
