What happens here

With the handle removed, you will see the valve's packing nut. To unscrew it, grab two adjustable wrenches. Use one wrench to firmly hold the main body of the shut-off valve to prevent it from turning or twisting the plumbing pipe in the wall. With the other adjustable wrench, grip the packing nut and turn it counter-clockwise to loosen it. Once sufficiently loose, you should be able to continue unscrewing the packing nut and the entire valve stem assembly by hand. Carefully pull the entire internal stem assembly, which includes the packing nut and the stem, out from the valve body.

Goal: Extract the internal working components of the valve to expose the seals.

What they say

Hide

reason why these multi-turn valves fail. Grab a screwdriver, pop this handle off, twist the screw counterclockwise. Grab two wrenches, one for a backup, and this not counter clockwise. Unscrew this packing nut and look right there. This washer right here is the biggest failure. Like look at that. It's brittle, it's a black rubber and it breaks apart
