I am trying to remove the stem below to fix a dripping faucet. I use a wrench to loosen around the hex with the arrow. With some force the stem begins to loosen (the threaded-looking part below loosens as well). At some point however, I cannot loosen any further, nor can I pull the stem out vertically.
I am not sure of the brand of the faucet, but it's also pictured. Any ideas? Is this stem supposed to NOT come out? Thanks.
