What happens here

After removing the retaining nut, the internal cartridge is pulled directly out of the valve body. The presenter notes a 'spring action' as it comes out. Upon inspection, the cartridge is heavily corroded, covered in rust-like deposits and mineral buildup, and appears to have internal components that are broken or severely degraded. The presence of 'junk' and 'fatty pieces' (debris) is clearly visible.

That Fix It GuyAir Force–trained plumber

Brian learned plumbing in the U.S. Air Force and has plumbed his way around the world. Now he films the fixes homeowners actually face: slow toilets, dripping faucets, clogged drains, failing water heaters and disposals. He shows what broke, why it broke, and how to fix it for a fraction of the cost of replacing it. He's particular about the right part, too: no snappy traps, no chemical drain cleaners. His rule: if he can do it, you can do it.
