It is a Delta faucet that from another post I am guessing is "of a newer type where the water flows through the spout and out the aerator via a plastic tube that runs inside of the metal "spout" (this allows manufacturers to avoid metallurgical complications related to the amount of toxic lead in the brass used for the spout). The reason I think it's this kind of faucet is because I can push the current aerator up and down (in and out of) the faucet spout. I was able to seemingly unscrew the aerator somewhat (which is why it's scratched ip) but it was really difficult and only made it wobblier so I'm not sure if I'm actually unscrewing the aerator or just twisting up the inside tube. I want to put a new "Rotating Faucet Extender/Swivel Robotic Arm Sink Aerator" I got off Amazon but I'm only renting here and really don't want to break the faucet just trying to change the aerator. Any help would be appreciated.
