Review on Pfister 910-9000 Ceramic Valve: A Reliable Solution for Smooth Faucet Operation by Todd Roybal

Like some other reviewers, mine came completely disassembled with no instructions. I spent a lot of time looking for a video showing how the parts of the cartridge fit together; They all only show the installation of an already assembled cartridge. After figuring it out, I took it apart again to take the step-by-step photos included in this review. A little puzzle, not higher mathematics. There was also a problem with my faucet because the old (non-ceramic) cartridge left part of itself when I removed it. So at first it seemed that the new cartridge would not work. After figuring this out and removing the remnants of the old cartridge, the new one stood up normally. That was about a month ago. Works well, nice and smooth.
